+ GNU GENERAL PUBLIC LICENSE
+ Version 1, February 1989
+
+ Copyright (C) 1989 Free Software Foundation, Inc.
+ 675 Mass Ave, Cambridge, MA 02139, USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The license agreements of most software companies try to keep users
+at the mercy of those companies. By contrast, our General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. The
+General Public License applies to the Free Software Foundation's
+software and to any other program whose authors commit to using it.
+You can use it for your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Specifically, the General Public License is designed to make
+sure that you have the freedom to give away or sell copies of free
+software, that you receive source code or can get it if you want it,
+that you can change the software or use pieces of it in new free
+programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of a such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must tell them their rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+\f
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License Agreement applies to any program or other work which
+contains a notice placed by the copyright holder saying it may be
+distributed under the terms of this General Public License. The
+"Program", below, refers to any such program or work, and a "work based
+on the Program" means either the Program or any work containing the
+Program or a portion of it, either verbatim or with modifications. Each
+licensee is addressed as "you".
+
+ 1. You may copy and distribute verbatim copies of the Program's source
+code as you receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this
+General Public License and to the absence of any warranty; and give any
+other recipients of the Program a copy of this General Public License
+along with the Program. You may charge a fee for the physical act of
+transferring a copy.
+
+ 2. You may modify your copy or copies of the Program or any portion of
+it, and copy and distribute such modifications under the terms of Paragraph
+1 above, provided that you also do the following:
+
+ a) cause the modified files to carry prominent notices stating that
+ you changed the files and the date of any change; and
+
+ b) cause the whole of any work that you distribute or publish, that
+ in whole or in part contains the Program or any part thereof, either
+ with or without modifications, to be licensed at no charge to all
+ third parties under the terms of this General Public License (except
+ that you may choose to grant warranty protection to some or all
+ third parties, at your option).
+
+ c) If the modified program normally reads commands interactively when
+ run, you must cause it, when started running for such interactive use
+ in the simplest and most usual way, to print or display an
+ announcement including an appropriate copyright notice and a notice
+ that there is no warranty (or else, saying that you provide a
+ warranty) and that users may redistribute the program under these
+ conditions, and telling the user how to view a copy of this General
+ Public License.
+
+ d) You may charge a fee for the physical act of transferring a
+ copy, and you may at your option offer warranty protection in
+ exchange for a fee.
+
+Mere aggregation of another independent work with the Program (or its
+derivative) on a volume of a storage or distribution medium does not bring
+the other work under the scope of these terms.
+\f
+ 3. You may copy and distribute the Program (or a portion or derivative of
+it, under Paragraph 2) in object code or executable form under the terms of
+Paragraphs 1 and 2 above provided that you also do one of the following:
+
+ a) accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ b) accompany it with a written offer, valid for at least three
+ years, to give any third party free (except for a nominal charge
+ for the cost of distribution) a complete machine-readable copy of the
+ corresponding source code, to be distributed under the terms of
+ Paragraphs 1 and 2 above; or,
+
+ c) accompany it with the information you received as to where the
+ corresponding source code may be obtained. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form alone.)
+
+Source code for a work means the preferred form of the work for making
+modifications to it. For an executable file, complete source code means
+all the source code for all modules it contains; but, as a special
+exception, it need not include source code for modules which are standard
+libraries that accompany the operating system on which the executable
+file runs, or for standard header files or definitions files that
+accompany that operating system.
+
+ 4. You may not copy, modify, sublicense, distribute or transfer the
+Program except as expressly provided under this General Public License.
+Any attempt otherwise to copy, modify, sublicense, distribute or transfer
+the Program is void, and will automatically terminate your rights to use
+the Program under this License. However, parties who have received
+copies, or rights to use copies, from you under this General Public
+License will not have their licenses terminated so long as such parties
+remain in full compliance.
+
+ 5. By copying, distributing or modifying the Program (or any work based
+on the Program) you indicate your acceptance of this license to do so,
+and all its terms and conditions.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the original
+licensor to copy, distribute or modify the Program subject to these
+terms and conditions. You may not impose any further restrictions on the
+recipients' exercise of the rights granted herein.
+\f
+ 7. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of the license which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+the license, you may choose any version ever published by the Free Software
+Foundation.
+
+ 8. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+\f
+ Appendix: How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to humanity, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these
+terms.
+
+ To do so, attach the following notices to the program. It is safest to
+attach them to the start of each source file to most effectively convey
+the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) 19yy <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 1, or (at your option)
+ any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program; if not, write to the Free Software
+ Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) 19xx name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the
+appropriate parts of the General Public License. Of course, the
+commands you use may be called something other than `show w' and `show
+c'; they could even be mouse-clicks or menu items--whatever suits your
+program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the
+ program `Gnomovision' (a program to direct compilers to make passes
+ at assemblers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+That's all there is to it!

+<h2>Overview</h2>
+<p>This page documents the free, open-source program <a href="http://www.cs.kent.ac.uk/~djb/pgn-extract">pgn-extract</a>, which is designed
+to support the processing, searching and extraction of chess games from files
+written in PGN format.
+There are several ways to specify the criteria on
+which to extract: textual move sequences, the position reached after a
+sequence of moves, information in the tag fields, and material balance
+in the ending.
+Full ANSI C source and a 32-bit Windows binary for the program are available
+under the terms of the <a href="#license">GNU General Public License</a>.
+The program includes a semantic analyser which will
+report errors in game scores and it is also able to detect duplicate
+games found in one or more of its input files.
+
+<p>The range of input move formats accepted is fairly wide and includes
+recognition of lower-case piece letters for English and upper-case
+piece letters for Dutch and German.
+The default output is in English Standard
+Algebraic Notation (SAN), although there is some support for output
+in different notations.
+
+<p>Extracted games may be written out either including or excluding
+comments, NAGs, and variations. Games may be given ECO classifications
+derived from the accompanying file eco.pgn, or a customised version
+provided by the user.
+
+<p>Plus, lots of other useful features that have gradually found their
+way into what was once a relatively simple program!

+<h2 id="flag-summary">Flag/Command-line Argument Summary</h2>
+<p>There follows a brief summary of the different flags taken by pgn-extract, such
+as is produced by the -h flag.
+However, you are strongly advised to read the remainder
+of this file before attempting to use pgn-extract in earnest.
+<ul>
+ <li>-7 - output only the seven tag roster for each game. Other tags (apart
+ from FEN and possibly ECO/Opening/Variation) are discarded
+ (See <a href="#-e">-e</a>).
+ <li>-aoutputfile - the file to which extracted games are to be appended.
+ See <a href="#output">-o</a> flag for overwriting an existing file.
+ <li>-Aargsfile - read the program's arguments from argsfile.
+ <li>-b[elu]num - restricted bounds on the number of moves in a game.
+ <ul>
+ <li>lnum set a lower bound of 'num' moves,
+ <li>unum set an upper bound of 'num' moves,
+ <li>otherwise num (or enum) means equal-to 'num' moves.
+ </ul>
+ <li>-cfile[.pgn] - Use file as a list of check files for duplicates.
+ <li>-C - don't include comments in the output. Ordinarily these are retained.
+ <li>-dduplicatefile - the file to which duplicate extracted games are
+ to be written.
+ <li>-D - don't output duplicate extracted game scores.
+ <li>-eECO_file - perform ECO classification of games. The optional
+ ECO_file should contain a PGN format list of ECO lines
+ Default is to use eco.pgn from the current directory.
+ <li>-E[123 etc.] - split output into separate files according to ECO.
+ <ul>
+ <li>E1 : Produce files from ECO letter, A.pgn, B.pgn, ...
+ <li>E2 : Produce files from ECO letter and first digit, A0.pgn, ...
+ <li>E3 : Produce files from full ECO code, A00.pgn, A01.pgn, ...
+ <li>Further digits may be used to produce non-standard further
+ refined division of games.
+ </ul>
+ All files are opened in append mode.
+ <li>-ffile_list - file_list contains the list of PGN files to be
+ searched - one per line (see <a href="#-f">-f</a>).
+ <li>-F - output a FEN string comment of the final game position.
+ <li>-h - print a list of command-line options.
+ <li>-? - same as --help.

+ <li>-M - Match only games which end in checkmate.
+ <li>-noutputfile - Write all valid games not otherwise output to outputfile.
+ <li>-N - don't include NAGs in the output. Ordinarily these are retained.
+ <li>-ooutputfile - the file to which extracted games are to be written.

+ <li>-P - don't match permutations of the textual variations (<a href="#-v">-v</a>).
+ <li>-r - report any errors but don't extract (<a href="#-r">-r</a>).
+ <li>-Rtagorder - Use the tag ordering specified in the file tagorder.
+ <li>-s - silent mode don't report each game as it is extracted.

+ option must precede the -t or -T options.
+ <li>-ttagfile - file of player, date, result, or FEN extraction criteria.
+ <li>-Tcriterion - player, date, eco code, hashcode, annotator or result, extraction criteria.
+ <li>-U - don't output games that only occur once. (Use with -d to
+ identify duplicates in multiple files.)

+
+<h2 id="usage">Usage and Flags/Command-line Arguments</h2>
+<p>pgn-extract takes an arbitrary number of game scores as input and outputs
+zero or more of these games, typically in English Standard Algebraic
+Notation (SAN). Which of the input games are output, and the style
+of the output, depend upon the particular set of command line flags
+passed to pgn-extract.
+The general form for calling pgn-extract is as follows:
+<pre>
+pgn-extract [flags] [input-game-files]
+</pre>
+
+<p>In its simplest form, calling pgn-extract with no arguments will cause
+it to read games from its standard input, check them and reproduce those
+without errors in SAN notation on its standard output.
+
+<h2 id="input">Game Input Format</h2>
+<p>This program's principle aim is to be able to read PGN files and output
+games of interest. It follows that the input should look reasonably like PGN to
+start with. This means that it doesn't cope well with files that
+contain news article or mail headers, for instance, although it does
+make an attempt to skip text that is obviously not game related between
+games. Having said that, it does not require the move text be in
+Standard Algebraic Notation (SAN). It will accept quite a few common
+formats including:
+<ul>
+ <li>Algebraic
+ <li>Long Algebraic
+ <li>various commonly-used intervening characters, such as : - x
+ <li>Dutch and German upper case piece letters.
+ (Support for Russian piece letters is in prototype.)
+ <li> lower-case English piece characters (except that it will always prefer
+ 'b' to mean a pawn move rather than a Bishop move).
+</ul>
+<p>It does not
+require that there be any move numbers or PGN headers preceding a game,
+as long as the move text is terminated by a valid result designation:
+*, 1-0, 0-1, 1/2-1/2 (1/2 is also accepted).
+This makes the program reasonably suitable for entering raw game text and
+having it reformatted in proper SAN with a full set of headers.
+
+<h2 id="-f">File of PGN files (-f)</h2>
+<p>Normally, the input files from which games are to be extracted are listed on the
+command line:
+<pre>
+pgn-extract file1.pgn [file2.pgn ...]
+</pre>
+
+<p>An alternative to listing the game files on the command line is to list
+their names, one per line, in a file which is then given after the -f flag:
+<pre>
+pgn-extract -ffile_list
+</pre>
+
+<p>In order to save the output in a file rather than standard output,
+use <a href="#output">-o, --output, -a, --append</a> to indicate the output
+file name, for instance:
+<pre>
+pgn-extract -oall.pgn file1.pgn file2.pgn file3.pgn
+pgn-extract --output all.pgn file1.pgn file2.pgn file3.pgn
+</pre>
+
+<p>While pgn-extract can be used simply to check and reformat all the input games,
+it is more usual to use it to select subsets of the input games.
+Several different criteria are available on
+which to extract: <a href="#variations">move variations</a>,
+<a href="#-t">information in the tag fields</a>, and
+<a href="#-z">material balance
+in the ending</a>, for instance.
+All of these criteria are described in detail below.
+
+<h2 id="output">Output Files (-o, --output, -a, --append)</h2>
+<p>In order to output all matched games to a single new file, the -o flag is used:
+<pre>
+pgn-extract -onew.pgn file1.pgn file2.pgn
+</pre>
+<p>This has the effect of creating new.pgn from the contents of file1.pgn
+and file2.pgn.
+The games
+in both source files are checked and rewritten, if necessary, into SAN.
+Any previous contents of new.pgn will be lost with the -o flag. In order to
+avoid this and append to an existing file, use the -a flag:
+<pre>
+pgn-extract -anew.pgn file1.pgn file2.pgn
+</pre>
+<p>Note that there must be no space between either -o or -a and the output file name.
+
+<p>The long-form --output and --append are provided as alternatives to -o and -a,
+respectively. In these cases, there must be a space between the
+flag and the output filename. For instance:
+<pre>
+pgn-extract --output new.pgn file1.pgn file2.pgn
+pgn-extract --append new.pgn file1.pgn file2.pgn
+</pre>
+
+<h2 id="-r">Check for Errors (-r)</h2>
+<p>Check the input files for errors but do not output any matched games.
+Useful for cleaning up files of games before proper processing.
+<pre>
+pgn-extract -r file.pgn
+</pre>
+<p>Useful with -s (silent mode) for checking a big file of games without
+having progress reported and just seeing the errors.
+
+<h2 id="keepbroken">Retaining games with errors</h2>
+<p>Normally, pgn-extract reports games with errors but does not output them.
+Games with errors may be output with the --keepbroken argument.
+The errors are still reported by the
+moves from the point where the error was detected onwards are placed in a comment rather
+than being retained as part of the game.
+
+<h2 id="-l">Log files (-l, -L)</h2>
+<p>Error messages and verbose reporting is done to the standard error
+output unless the -l or -L flag is used.
+Both are immediately followed by the name of a file to which a log
+should be written.
+The -l flag creates a new log file, while -L appends to an existing log file:
+<pre>
+pgn-extract -llog.txt file.pgn
+pgn-extract -Llog.txt file.pgn
+</pre>
+<p>This option is useful in combination with <a href="#-r">-r</a> (report)
+to generate diagnostic information without outputting games while game
+data is being checked and cleaned.
+<p>A log file will contain only error reports if the <a href="#-s"">-s</a>
+(silent) flag is used.
+
+<h2 id="variations">Variations (-v, -x and -P)</h2>
+<p>There are two distinct ways to specify variations of interest;
+positional variations (the <a href="#-x">the -x</a> flag) and
+textual variations (the <a href="#-v">-v</a> flag).
+The major difference between the two is that positional variations
+specify a complete move sequence whose end position is the primary
+point of interest, whereas textual variations allow incomplete and
+fuzzy move sequence matches on the text of a game to select games.
+Whilst it is possible to use both
+flags together, this would be unusual as a game must match with both to
+be extracted.
+
+<ul>
+<li id="-x"><p>Positional Variations (-x)<br />
+<p>The variations in which you are interested should be placed in a file
+whose name is supplied with the -x flag. For instance:
+<pre>
+pgn-extract -xvars
+</pre>
+<p>where each variation is
+listed on a single line in the file vars (the filename is immaterial).
+The following set of moves:
+<pre>
+e4 c5 Nf3 d6 d4 cxd4 Nxd4 Nf6 Nc3 a6
+</pre>
+<p>indicates that you wish to pick up all games reaching the Najdorf
+variation position of the Sicilian Defence.
+Games reaching the end position of this sequence are
+selected regardless of the route that was taken to reach it. This
+allows various transpositional sequences to be specified by quoting
+just one line to reach the required point. Therefore, games employing
+the following move order will be picked up by quoting the line above.
+<pre>
+e4 c5 Nc3 d6 Nge2 Nf6 d4 cxd4 Nxd4 a6
+</pre>
+<p>A position is considered to match a required variation if it generates
+the same board hash value. In the interests of reasonable efficiency,
+no attempt is made to actually examine the state
+of the board. There is, therefore, the potential for false hits but in
+my usage of pgn-extract I have not found this to be a problem.
+
+<p>With this option, games are only searched to a depth approximately equal
+to the length of the longest positional variation, in order to make
+processing of large data sets faster than with a search of the whole
+game.
+
+<p>A comment line may be placed in a variation file by using a '%' as the
+first character of the line. Move numbers are optional within the
+list of moves.
+
+<p>Positional matches are also available using a FEN description of the
+desired position.
+See the description of the <a href="#-t">-t flag</a>
+for how to specify a FEN position,
+and <a href="#-F">the -F flag</a>
+for a simple way to generate a FEN description from
+a game score.
+
+<li id="-v"><p>Textual Variations (-v) <br />
+<p>With this option, the matching is purely textual in nature,
+in contrast to the <a href="#-x">-x</a> flag. The -v flag works by
+string matching on the input text of moves,
+so there is no facility for picking up transpositions automatically.
+The variations in which you are interested should be placed in a file
+whose name is supplied with the -v flag. For instance:
+<pre>
+pgn-extract -vvars
+</pre>
+<p>Each variation should be listed on a single line
+in the file vars (the filename is immaterial).
+The move sequence:
+<pre>
+e4 c5 Nf3 d6 d4 cxd4 Nxd4 Nf6 Nc3 a6
+</pre>
+<p>indicates that you wish to pick up all games following the normal move
+order of the Najdorf variation of the Sicilian Defence, and
+<pre>
+d4 Nf6 c4 e6 Nc3 Bb4
+</pre>
+<p>that you are interested in Nimzo-Indian games.
+The order in which the moves are played by either White or Black
+is immaterial. All combinations are tried, so the ordering:
+<pre>
+c4 e6 Nc3 Bb4 d4 Nf6
+</pre>
+<p>will produce the same set of matches as the previous ordering of the
+Nimzo-Indian moves (see <a href="#-P">the -P flag</a> for how
+to prevent this).
+
+<p>A comment line may be placed in a variation file by using a '%' as the
+first character of the line. Move numbers are optional within the
+list of moves.
+
+<p>As transpositions are not picked up automatically with this flag,
+if you also wanted to
+recognise the following as a Najdorf, you would have to add this line
+to the variations file in addition to that given above:
+<pre>
+e4 c5 Nc3 d6 Nge2 Nf6 d4 cxd4 Nxd4 a6
+</pre>
+<p>However, because of the way in which the matching is done, it is
+possible to specify slight alternatives on the way in which individual
+moves are written. Notational alternatives for a single move are just
+written separated from each other with a non-move character. This
+variation specifies both the shorter and longer ways of writing the
+captures in a Najdorf:
+<pre>
+e4 c5 Nf3 d6 d4 cxd4|cd Nxd4|Nd4 Nf6 Nc3 a6
+</pre>
+<p>However, given the variety of possible ways of writing various moves in
+non-SAN format, e.g.
+<pre>
+cxd4|cd|c5d4|c5-d4
+</pre>
+<p>variation lists can get quite messy and I believe that this approach is
+best avoided by ensuring that the input is proper SAN and only using
+SAN notation in the variations file. In this way, the alternative-separator
+can then be used purely for indicating genuine alternative moves at
+that point, e.g.
+<pre>
+e4 c5 Nf3 d6 d4|d3
+</pre>
+<p>An important point when listing moves is that check and mate indicators
+should be included where appropriate, otherwise moves incorporating
+these characters in games to be searched will fail to match.
+
+<p>There is little point in using the -v flag in preference to
+the <a href="#-x">-x</a> flag
+if you are only interested in finding games that reach a particular
+position. The real use for -v is when you wish to pick up games
+in a more general way. For instance, the character '*' may be used in
+place of any move to indicate that you don't care what was played at
+that point. So the following:
+<pre>
+* b6
+</pre>
+<p>means that you are interested in all games in which Black replied
+1 ... b6 regardless of White's first move.
+The sequence:
+<pre>
+d4 * c4 * Nc3 *
+</pre>
+<p>will pick up Nimzo-Indian, Grunfeld, King's Indian, etc. defences.
+This notation is not possible with <a href="#-x">positional variations</a>.
+
+<p>In addition, the character '!' may be used in front of any move to
+indicate that you wish to disallow particular moves from matching at
+this point. For instance, if you want to find Sicilian games where
+White did not reply with Nf3 at move 2 you would specify:
+<pre>
+e4 c5 !Nf3
+</pre>
+<p>If you wished to disallow 2.Ne2 as well then
+<pre>
+e4 c5 !Nf3|Ne2
+</pre>
+<p>does the job. (Adding parentheses makes no difference as the '!' is
+applied to all of the following move string.)
+
+<p>Care should be taken combining '!', '*' and variation permutations (see <a
+href="#-P">the -P flag</a>).
+Disallowed moves take precedence over '*' moves. If a single
+disallowed move is found in a game within the length of the variation,
+that game is excluded. This was the most sensible interpretation that
+I could find to place on this usage.
+
+<li id="-P"><p>Textual Variation Permutations (-P)<br />
+<p>Normally, all permutations of a textual variation (see <a href=
+"#-v">the -v flag</a>) are tried against the
+moves of a game. This cuts down on the number of separate
+transpositional orderings that it is necessary to list, at the cost of
+slower matching of each game. If the following were used to look for
+Nimzo-Indian games:
+<pre>
+d4 Nf6 c4 e6 Nf6 Nc3 Bb4
+</pre>
+<p>a side-effect would be that it will also pick up games which start as:
+<pre>
+1. c4 Nf6 2. Nc3 e6 3. d4 Bb4
+</pre>
+<p>for instance.
+The -P flag requests that textual variations are matched against the
+moves of the game strictly in the order in which they are listed,
+without trying different orders. So, if you want to find only those
+games that follow a particular move order, use this flag to suppress
+permutations.
+</ul>
+
+<h2 id="duplicates" id="-d" id="-D">Duplicate Games (-d, --duplicates and -D or --noduplicates, plus -Z)</h2>
+<p>If either the -d, --duplicates or -D flag is used, pgn-extract
+attempts to recognise duplicate extracted games.
+Using the -d or --duplicates flag indicates that you wish copies of the
+duplicate
+games to be written to the indicated file:
+<pre>
+pgn-extract -ddupes.pgn -ounique.pgn file.pgn
+pgn-extract --duplicates dupes.pgn --output unique.pgn file.pgn
+</pre>
+<p>will both extract from file.pgn the unique set of games into unique.pgn and
+the duplicates (i.e., the second and subsequent copies of a game)
+to dupes.pgn.
+A comment identifying in which file a
+duplicate was found precedes the first duplicate found in that file and
+each duplicate game has a prefix comment indicating the file in which
+the first version was found.
+Note that there must be no space between <code>-d</code> and the filename
+but a space between if <code>--duplicates</code> is used.
+
+<p>With the -D flag duplicate games are suppressed
+from the output. These two flags are mutually exclusive, therefore.
+
+<p>Duplicates are identified by comparing a hash value for the board of
+the end positions of extracted games and an additional cumulative hash
+value generated from the move sequence.
+If these both values match then games are considered to be
+duplicates.
+This is not guaranteed to be exact but it gives a good approximation.
+If the position is important but the move sequence is not then use
+<a href="#fuzzydepth">--fuzzydepth</a>.
+
+<p>You should note that games are only considered to be duplicates on the
+basis of the moves played. It may be that a game considered to be a
+duplicate contains annotations and variations not present in the one
+found earlier, so it might be necessary to do some swapping around to
+obtain those you really wish to retain. You should, therefore, use the
+-D flag with caution if you are trying to reorganise your master
+collection rather than selecting out specific games for examination.
+(See also <a href="#-U">the -U flag</a>.)
+
+<p>Detecting duplicates requires memory for the storage of a hash table
+containing information on each game.
+Large databases can result in a MallocOrDie error.
+If this is the case, try using the -Z flag which
+forces pgn-extract to store its hash table externally, in a file called
+virtual.tmp. Each game requires 16 bytes of file space. Clearly, if a
+very large database is being processed, there is a risk of filling up
+the available file space if there is insufficient available.
+
+<h2 id="fuzzydepth">Positional Duplicates Match</h2>
+<p>This flag allows a match on the basis of board position at the
+indicated number of plies or the end of the game.
+The flag is followed by the ply depth at which matches are to be
+considered. The value 0 is used to request matching at the end of
+games. It should always be used in combination with at least
+one of: <a href="#duplicates">-d/--duplicates, -D/--noduplicates</a>, <a href="#-U">-U</a>.
+
+<p>In contrast to the <a href="#duplicates">--duplicates</a> matching,
+the match does not consider the move sequence used to reach the
+match position.
+
+<p>For example:
+<pre>
+pgn-extract --fuzzydepth 40 -D games.pgn
+</pre>
+<p>would suppress from the output multiple copies of games reaching
+identical positions after 40 ply.
+
+<p>The following example would suppress the unique games and
+store the games considered to be duplicate at their final
+position in dupes.pgn:
+<pre>
+pgn-extract --fuzzydepth 0 -U -ddupes.pgn games.pgn
+</pre>
+
+<h2 id="-U">Suppression of Unique Games (-U or --nounique)</h2>
+<p>The -U flag suppresses output of the first occurrence of a particular
+game. This is useful when combined with <a href="#duplicates">the -d flag</a>
+as a means of
+identifying just those games that are duplicated in a list of multiple
+files. As the duplicate games are commented with the file in which
+they were located, it then becomes possible to prune a set of files
+containing common games. For instance, suppose oldfile.pgn contains a
+set of games without duplicates, and you wish to know which games in
+newfile.pgn already occur in oldfile.pgn:
+<pre>
+pgn-extract -U -ddupes.pgn oldfile.pgn newfile.pgn
+</pre>
+<p>will write to dupes.pgn the duplicate games so that you can go through
+newfile.pgn and remove them. Of course, if you simply want to hold the
+combined set of unique games in a single file you would use something like:
+<pre>
+pgn-extract -D -onewset.pgn oldfile.pgn newfile.pgn
+</pre>
+<p>See <a href="#duplicates">Duplicate Games</a> for dealing
+with MallocOrDie errors.
+
+<h2 id="-c">Check Files for Duplicates (-c, --checkfile)</h2>
+<p>Check files contain games that are to be used in duplicate detection,
+but not to form part of the output. If the filename appended to the
+argument has a .pgn/.PGN suffix it is assumed to be a single file of
+games. If it does not have this suffix then it is assumed to be a file
+containing a list of the names of PGN game files, one per line, to be
+used as check files.
+
+<p>A typical use for this is to select new games of
+interest from a file that probably contains games that exist elsewhere.
+In the following example, we wish to select Nimzo-Indian games from
+newfile.pgn that don't already occur in the master file nimzo.pgn:
+<pre>
+pgn-extract -cnimzo.pgn -vnimzo.var -D -onewnimzo.pgn newfile.pgn
+</pre>
+<p>The games in nimzo.pgn act as the source for duplicate detection so
+duplicates of these will be suppressed (<a href="#duplicates">the -D flag</a>).
+Only those games from
+newfile.pgn that are not in nimzo.pgn will be output to newnimzo.pgn.
+Contrast this behaviour with the following, which would create a new
+master file of games from the combination of nimzo.pgn and
+newfile.pgn:
+<pre>
+pgn-extract -vnimzo.var -D -onewnimzo.pgn nimzo.pgn newfile.pgn
+</pre>
+
+<p>--checkfile is available as an alternative to -c and must be followed
+by a space before the filename, e.g.:
+<pre>
+pgn-extract --checkfile nimzo.pgn -vnimzo.var -D -onewnimzo.pgn newfile.pgn
+</pre>
+
+<h2 id="-t">Matching on Tag Criteria (-t)</h2>
+<p>There are two ways to specify that you wish to use information in the
+tag fields as extraction criteria: the -t flag and
+<a href="#-T">the -T flag</a>. The -t flag takes a file name
+argument and is the preferred method because of its ease of use and
+greater flexibility:
+<pre>
+pgn-extract -ttags games.pgn
+</pre>
+<p>where tags is an arbitrary file name.
+In the file are listed tag name and value pairs
+corresponding to the extraction criteria you wish to use.
+Each line of this file should be of the form:
+<pre>
+PGN-Tag-name Tag-string
+</pre>
+for instance:
+<pre>
+White "Tal"
+</pre>
+<p>(note the need to include double quotes around the tag value).
+This requests that only those games where Tal had the White pieces are
+to be considered for extraction.
+If you wish to limit the year in
+which those games were played you might list:
+<pre>
+White "Tal"
+Date "1962"
+</pre>
+<p>Multiple pairs with the same tag name are or-ed together so:
+<pre>
+% Find games in the period 1960-1962.
+Date "1960"
+Date "1961"
+Date "1962"
+</pre>
+<p>will select all games from the three listed years.
+Note that comments may be included in the tag file.
+
+<p>In general, tags names that differ are and-ed together, so:
+<pre>
+White "Tal"
+Black "Fischer"
+Date "1962"
+Result "1-0"
+</pre>
+<p>selects only those games that Tal won with the White pieces against
+Fischer in 1962.
+
+<p>It is important to note that:
+<pre>
+White "Tal"
+Black "Tal"
+</pre>
+<p>does not find all games played by Tal, but only those that he played
+against himself. In order to overcome this, I have introduced a
+non-PGN tag that should only be used in the extraction criteria file:
+<pre>
+Player "Tal"
+Date "1962"
+</pre>
+<p>finds all games from 1962 in which Tal had either the White pieces or
+the Black. In effect, the White and Black player lists are or-ed
+together rather than and-ed using this pseudo-tag.
+
+<p>Prefix matching on tag values is done so that a criterion should be a prefix
+of the complete Tag string. Thus,
+<pre>
+Player "Karpov"
+</pre>
+<p>would match:
+<pre>
+[White "Karpov"]
+[White "Karpov, A"]
+[White "Karpov, An"]
+[White "Karpov, Alexander"]
+</pre>
+<p>but not
+<pre>
+[White "Anatoli Karpov"]
+</pre>
+<p>See the <a href="#-S">-S</a> flag for a soundex facility with tag matching.
+
+<p>All tag criteria except ECO classification are checked before the moves
+of the game in the interests of efficiency (tag checking is relatively
+fast whereas positional checking of the game is not). Only once the
+game has been processed is it checked to see whether an ECO tag match
+has been requested. The consequence of this is that using <a href="#-e">the
+-e flag</a>
+in combination with ECO tag criteria you can search for games in
+particular ECO lines without an ECO tag having been present in the
+input form.
+
+<ul>
+<li id="fen-t"><p>FEN positional matches with -t<br />
+<p>Use of a FEN tag with the -t flag has
+a special meaning. Rather than using this to match FEN tags in
+the header of a game, a FEN description is used to indicate a search
+for a positional match (similar to use of <a href="#-x">the -x</a> flag).
+If a FEN description is provided with the -t flag, the indicated
+position is searched for in each game processed, and only those
+games that reach the indicated position are output.
+A FEN tag-pair for the starting position would be described by:
+<pre>
+FEN "rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - 0 1"
+</pre>
+<p>The position after the two moves e4 c5 would be:
+<pre>
+FEN "rnbqkbnr/pp1ppppp/8/2p5/4P3/8/PPPP1PPP/RNBQKBNR w KQkq c6 0 2"
+</pre>
+<p>See details of <a href="#-F">the -F flag</a> for a simple way to generate a FEN
+description from a game score.
+
+<p>There is a variation on use of a FEN with -t flag.
+The pseudo tag FENPattern takes a FEN-like description of a board
+containing meta characters that allow a fuzzy board match.
+In addition to the standard FEN characters having their usual
+meaning (1, 2, ... 8, R, N, B, etc.), the following
+meta characters are used:
+
+<ul>
+ <li>? - match any square. The square may be occupied or unoccupied.
+ <li>! - match any occupied square. The square may be occupied by a piece of any type and colour.
+ <li>A - match a single White piece.
+ <li>a - match a single Black piece.
+ <li>* - match zero or more squares, occupied or unoccupied.
+ <li>[<em>xyz</em>] - match any of <em>xyz</em>, where <em>xyz</em> represents
+ any of the English piece-letter names (KQRNBPkqrnbp) and is case-sensitive.
+ In addition, 'A' and 'a' (as defined above) are available.
+ For instance: [Qq] matches either a White or Black queen;
+ [BbNn] matches any White or Black bishop or knight;
+ [Ar] matches any White piece or a Black rook.
+ <li>[^<em>xyz</em>] If the first character inside the square brackets
+ is '^' then the match is inverted; i.e., match any piece that is <em>not</em>
+ listed. For instance, [^BbNn] matches any piece that is not
+ a White or Black bishop or knight.
+</ul>
+<p>Ranks within the pattern are separated with a '/' character, as usual,
+but there should be no characters other than the board position.
+<p>
+For instance:
+<pre>
+FENPattern "rnbqkbnr/*/*/*/*/*/*/RNBQKBNR"
+</pre>
+<p>would match any board in which at least every non-pawn piece is
+on its starting square.
+<pre>
+FENPattern "?????rk?/?????aaa/*/*/*/8/P[BP]P*/??KR????"
+</pre>
+<p>would match a board in which Black has a Kingside castled position behind three
+Black pieces (not necessarily pawns),
+White has a Queenside castled position with
+either a White pawn or bishop on b2 and the third rank is empty.
+</ul>
+
+<li id="date-t"><p>Date and Elo Matches with -t<br />
+<p>From a <a href="#-t">-t tag file</a>,
+more complex matching of dates and Elo values may be performed by
+placing an operator between the tag name and the tag string to be
+matched:
+<pre>
+Date < "1962"
+</pre>
+<p>would only match games played before 1962. Only the year value
+participates in the matching process, as this is done using integer
+values rather than strings.
+<pre>
+WhiteElo >= "2500"
+</pre>
+<p>only matches games where White is a strong player. Probably of more
+general use is another pseudo-tag that I have introduced purely for
+this purpose: Elo.
+<pre>
+Elo >= "2500"
+</pre>
+<p>matches games in which either player has an Elo tag matching that
+relationship.
+The operators allowed are >, >=, <, <=, =, and <> (not
+equal to).
+</ul>
+
+<h2 id="-T">Tag Criteria on the Command Line (-T)</h2>
+<p>An alternative to the <a href="#-t">-t flag</a> is the
+-T flag, for use where command line arguments are
+more convenient - perhaps where pgn-extract is being invoked from another
+program. The tag coverage is not as extensive as with a tag file, and
+the syntax is rather cumbersome. It is used as follows: after the -T
+comes a single letter from the limited set [abdeprw] to select string
+prefixes of the tag fields of a game. For instance:
+<ul>
+ <li>-TaAnnotator - Extract games Annotated by Annotator.
+ <li>-TbPlayer - Extract games where Player has the Black pieces.
+ <li>-TdDate - Extract games played on Date.
+ <li>-TeEco - Extract games with ECO designation Eco.
+ <li>-ThHashCode - Extract games with HashCode designation HashCode.
+ <li>-TpPlayer - Extract games where Player has either colour.
+ <li>-TrResult - Extract games with result Result.
+ <li>-TwPlayer - Extract games where Player has the White pieces.
+</ul>
+<p>For example,
+<pre>
+pgn-extract -TwTal -TbFischer file.pgn
+</pre>
+<p>would extract games from file.pgn in which Tal had the White pieces and
+Fischer the Black.
+
+<p>Criteria of the same tag type are or-ed together, so
+<pre>
+pgn-extract -Tr1-0 -Tr0-1 file.pgn
+</pre>
+<p>extracts only decisive games.
+
+<p>Criteria of different tag types are and-ed together so
+<pre>
+pgn-extract -TwTal -Td1962 -Tr1-0 file.pgn
+</pre>
+<p>would extract only those games in which Tal played with the White
+pieces in 1962 and won.
+
+<p>The ECO classification (see <a href="#-e">the -e flag</a>)
+is performed before attempting to match an ECO tag, so:
+<pre>
+pgn-extract -TeA01 -e file.pgn
+</pre>
+<p>will perform ECO classification on the input file and extract games
+with ECO classification A01 (Nimzo-Larsen attack), for instance.
+
+<ul>
+<li id="date-T"><p>Date Matches with -T<br />
+<p>A simple form of relational date matching is available.
+A date year may be prefixed with either 'b' or 'a' in order
+to match games played either before or after the specified date. This
+assumes that the date is stored in the game's date tag string in the
+normal form: YYYY.MM.DD
+
+<p>So,
+<pre>
+pgn-extract -Tdb1962 file.pgn
+</pre>
+<p>will look for games played before 1962. A much fuller capability
+is available in tag files with <a href="#-t">the -t flag</a>.
+</ul>
+
+<h2 id="-A">Argument Descriptions in a File (-A)</h2>
+<p>It can be inconvenient to repeatedly type long argument lists
+on the command line. The -A flag makes it possible to list
+arguments in a file, rather than on a command line. Each
+argument line within the file must be immediately preceded by
+a ':' (colon) character. Consider selecting games by Tal from
+a file caro.pgn and writing them to talgames.pgn. Using
+command line arguments, this would have the following form:
+<pre>
+pgn-extract -TpTal -otalgames.pgn caro.pgn
+</pre>
+<p>We can do the same job placing the argument list in the file args:
+<pre>
+% Select games by Tal.
+:-TpTal
+% Where to output the matched games.
+:-otalgames.pgn
+</pre>
+<p>and the same selection made with:
+<pre>
+pgn-extract -Aargs caro.pgn
+</pre>
+<p>Note that comments may be included using a '%' character.
+
+<p>Each argument should be listed on its own line, and all the
+arguments are available in this way.
+The PGN source files may also be listed in the argument file.
+They must be listed one per line, with a preceding colon
+character. So an alternative for the above would be:
+<pre>
+% Select games by Tal.
+:-TpTal
+% Where to output the matched games.
+:-otalgames.pgn
+% The game files to be read.
+:caro.pgn
+</pre>
+<p>and the command invoked as simply:
+<pre>
+pgn-extract -Aargs
+</pre>
+
+<p>The <a href="#-t">-t</a>, <a href="#-v">-v</a>, <a href="#-x">-x</a>,
+<a href="#-z">-z</a>, and <a href="#-R">-R</a>
+flags have slightly special treatment in an argument file.
+Where the tags, variations, positions, endings and/or roster ordering
+are to be read from
+files of those names, say, then the format of these arguments in the
+argument file might be as you would expect:
+<pre>
+:-ttags
+:-vvariations
+:-xpositions
+:-zendings
+:-Rroster
+</pre>
+<p>However, within an argument file, the file names are optional and,
+where omitted, the data that would have been stored in a file for
+these flags is listed on lines immediately following.
+For instance, an alternative to:
+<pre>
+:-TpTal
+</pre>
+<p>we could say:
+<pre>
+:-t
+Player "Tal"
+</pre>
+<p>Notice that no colon should be present on the lines following the
+flag line.
+In the following example, we select games won by Tal as White
+reaching a particular position in the Caro Kann:
+<pre>
+:-t
+White "Tal"
+Result "1-0"
+:-otalwins.pgn
+:-x
+e4 c6 d4 d5 exd5 cxd5
+% Which game files to process.
+:caro.pgn
+</pre>
+<p>The arguments file may, itself, also contain -A arguments. This should
+make it possible to build up hierarchies of game selection criteria
+if desired. However, beware that there is no check for circularities
+in the dependencies.
+
+<h2 id="-n">Outputting Games not Matched (-n)</h2>
+<p>The -n flag will cause all valid games not output via other criteria to
+be saved in a given file. The purpose of this is to make it easier to
+reorganise files in different ways. For instance, if you wish to remove
+all of the games played by Tal from one file, you might do:
+<pre>
+pgn-extract -TpTal -otalgames.pgn -nothers.pgn file.pgn
+</pre>
+<p>After which, the file others.pgn will contain all of the valid games
+from the original file, with the exception of Tal's.
+
+<h2 id="--selectonly">Outputting a single matched game (--selectonly)</h2>
+<p>The --selectonly flag takes a single numerical argument N (N > 0) to
+request that only the Nth matched game is output. For instance, if only the first
+game played against Fischer is required from a file of Tal games, the following
+would be used:
+<pre>
+pgn-extract -TpFischer --selectonly 1 talgames.pgn
+</pre>
+<p>Note that, once the required game has been output, the program will terminate and
+not continue processing the rest of the input files.
+
+<h2 id="notags">Don't Output Any Tags (--notags)</h2>
+<p>The tags for a game will not be output.
+
+<h2 id="suppress">Suppress annotations in the output (-C -N -V)</h2>
+<p>If comments (-C or --nocomments),
+NAGs (-N or --nonags) and/or variations (-V or --novars) are not required in
+the output then these can be suppressed by using one or more of these flags.
+
+<h2 id="nomovenumbers">Suppressing move numbers (--nomovenumbers)</h2>
+<p>Move numbers can be suppressed from the output with --nomovenumbers.
+Used in combination with
+<a href="#notags">--notags</a>,
+<a href="#noresults">--noresults</a>,
+<a href="#suppress">-C, -N, and -V</a>
+this can be used to output just the moves of a game:
+<pre>
+pgn-extract --nomovenumbers --noresults --notags -C -N -V file.pgn
+</pre>
+<p>If it is desired to have all the moves on a single line, use the <a href=
+"#-w">-w</a> flag as well.
+<p>See also the <a href="#plylimit">--plylimit</a> flag.
+
+<h2 id="noresults">Suppressing results (--noresults)</h2>
+<p>Results at the ends of games and variations
+can be suppressed from the output with --noresults.
+See <a href="#nomovenumbers">suppressing move numbers</a> for a possible use.
+
+<h2 id="plylimit">Limiting the number of plies (>= 0) output
+ (--plylimit)</h2>
+<p>The number of moves (actually plies) output for a game can be limited
+by using --plylimit. This must be followed by the maximum
+number of plies to be output for a game.
+For instance,
+<pre>
+pgn-extract --plylimit 10 --nomovenumbers --notags file.pgn
+</pre>
+<p>will output games up to a maximum of 10 plies (including variation lines),
+without game tags and no line numbers.
+
+<p>Note: If the game has not ended before the ply limit is reached then *
+will be used as the terminating result to indicate an incomplete game (see
+<a href="#noresults">--noresults</a> for how to suppress this.)
+
+<h2 id="-b">Setting bounds on the number of moves in a game (-b)</h2>
+<p>The -b flag allows you to select games which have a number of moves
+within the bounds you set. You can set a lower bound on the number of moves
+by using -bl ('l' = lower bound), or an upper limit
+by using -bu ('u' = upper bound). Both are followed by
+the number of moves so
+<pre>
+pgn-extract -bu20 file.pgn
+</pre>
+<p>will find brevities of 20 moves or less, whilst
+<pre>
+pgn-extract -bl60 file.pgn
+</pre>
+<p>will find games of 60 moves or move. Bounds may be combined so
+<pre>
+pgn-extract -bl30 -bu40 file.pgn
+</pre>
+<p>will find games in the range [30..40] moves. If neither 'l' nor 'u'
+is used, but just a number following the -b, this means that the number
+of moves must exactly match that number. Alternatively, 'e' can be
+used to stand for 'equal to'. The following are equivalent and find
+all games of exactly 35 moves.
+<pre>
+pgn-extract -b35 file.pgn
+pgn-extract -be35 file.pgn
+</pre>
+
+<h2 id="-M">Matching only games that end in checkmate (-M or --checkmate)</h2>
+<p>The -M flag requests that only games that end in checkmate are matched:
+<pre>
+pgn-extract -M file.pgn
+</pre>
+
+<h2 id="stalemate">Matching only games that end in stalemate (--stalemate)</h2>
+<p>The --stalemate flag requests that only games that end in stalemate are matched:
+<pre>
+pgn-extract --stalemate file.pgn
+</pre>
+
+<h2 id="underpromotion">Matching only games that contain an underpromotion
+(--underpromotion)</h2>
+<p>The --underpromotion flag requests that only games that contain an
+underpromotion are matched:
+<pre>
+pgn-extract --underpromotion file.pgn
+</pre>
+
+<h2 id="-e">ECO Classification (-e)</h2>
+<p>A <a href="ftp://ftp.cs.kent.ac.uk/pub/djb/pgn-extract/eco.pgn">PGN
+file of ECO classifications</a> is distributed with this version. I
+believe that this was put together by Ewart Shaw, Franz Hemmer and
+others, to whom appropriate thanks is due. The -e flag requests
+pgn-extract to add/replace ECO classifications in the games it outputs.
+This is done by firstly reading a file of ECO lines in PGN format
+(eco.pgn in the current directory, by default) and building a table of
+resulting positions. As the games are then read they are looked up in
+the table to find a classification. The deepest match is found.
+A match is allowed within six half moves of the length of the ECO line.
+The supplied file has ECO, Opening, and Variation tag strings for many
+lines. If present, pgn-extract will add/replace these as well as
+SubVariation tags if available.
+
+<p>An alternative file to the default eco.pgn may be supplied in two
+ways:
+<ul>
+ <li><p>Appending a file name to the -e flag
+<pre>
+-emy_eco_codes.pgn
+</pre>
+<p>Note that there must not be a space between the -e and
+the name of the file, otherwise the default ECO file will be assumed.
+ <li><p>By setting the environment variable ECO_FILE to the full path name
+of the file.
+Under Windows this can be done with
+<pre>
+set ECO_FILE=full-eco-file-path
+</pre>
+<p>at the Cmd window prompt, or more permanently via the
+System/Environment/Advanced area.
+Under UNIX csh this can be done with
+<pre>
+setenv ECO_FILE full-eco-file-path
+</pre>
+<p>in the .cshrc, for instance.
+</ul>
+
+<p>Having the ECO data read as plain text on program startup has the
+obvious disadvantage that there is a high initial time overhead. On the
+other hand, it has the advantage that users may add their own
+classifications to the file very easily. It is fairly demanding of
+memory, so you advised not to combine this with duplicate detection
+(<a href="#-U">-U</a>,
+<a href="#duplicates">-D and -d</a>), which can also consume a lot
+of memory with big databases.
+
+<p>Because an ECO tag match with either the <a href="#-t">-t flag</a> or
+the <a href="#-T">-T flag</a> is delayed until after ECO
+classification, this makes it relatively easy to select games with
+particular ECO codes even if they weren't present in the source form.
+
+<p>Usage of -e with the Seven Tag Roster flag (<a href="#-7">-7</a>)
+results in the ECO
+tags (ECO, Opening, Variation, SubVariation) being included in the
+output games.
+
+<h2 id="separate-output">Separate Output Files (-#, -E)</h2>
+<p>The -# and -E flags permit the output to be split into multiple files.
+However, be warned that where the input involves a lot of games,
+these flags might result in
+the creation of a large number of output files.
+
+<p>The -# flag takes an unsigned integer argument specifying the maximum number
+of games to output to a single file. Successive output files are numbered 1.pgn,
+2.pgn, etc. Any existing contents of these files are always overwritten on each
+run of pgn-extract.
+<pre>
+pgn-extract -#250 file.pgn
+</pre>
+<p>will check and split file.pgn into separate files of, at most, 250 games each.
+<pre>
+pgn-extract -#1 file.pgn
+</pre>
+<p>will split file.pgn into separate files containing only a single game each.
+
+<p>The -E flag normally takes a numeric argument of value 1, 2, or 3. This is
+used to indicate the level of subdivision required based upon the ECO tag
+found in a game.
+<pre>
+pgn-extract -E3 file.pgn
+</pre>
+<p>will fully subdivide file.pgn into separate files based on the full ECO
+code of each game, with names such as B03.pgn, A01.pgn, D45.pgn, etc.
+If a game does not contain an ECO tag, or the tag appears to be malformed,
+it will be written to a file called, noeco.pgn. All of these files are
+written to in append mode, so that existing contents are not lost. However,
+beware of using an input file whose name is the same as one that will be
+written to by this operation. This could lead to infinite operation.
+
+<p>Level 1 classification uses just the initial letter of the ECO
+classification to append to files A.pgn, B.pgn, etc. Level 2 uses the initial
+letter and first digit, producing A0.pgn, B3.pgn, etc.
+
+<p>In fact, values greater than 3 may be used to produce separation of even
+finer granularity if more than two digits have been used in the classification
+of a game.
+
+<h2 id="-S">Soundex Matching (-S)</h2>
+<p>There is a simple soundex algorithm available that attempts soundex
+matches on White, Black, Site, Event, and Annotator tags if the -S flag
+is used in combination with either the <a href="#-t">-t flag</a> or
+the <a href="#-T">-T flag</a>. The -S flag should
+precede all -t and -T arguments. It should be noted that the soundex
+matching does produce false matches.
+
+<h2 id="-w">Output Line Length (-w or --linelength)</h2>
+<p>The -w flag allows an approximate line length to be set for output.
+Normally games are output with lines up to a maximum of 75 characters.
+Use the -w flag if you want longer output lines.
+For instance, you might want all the moves of a game to appear on a single
+line. You would get this effect by specifying -w1000 (say):
+<pre>
+pgn-extract -w1000 file.pgn
+</pre>
+<p>If some games are more than 1000 characters long then just increase the value.
+
+<h2 id="-W">Output Format and Language (-W)</h2>
+<p>By default, pgn-extract rewrites the game score into English Standard Algebraic
+Notation (SAN) because it is reasonably flexible about the input form
+that it will accept. To prevent it from rewriting the original form of
+the moves it reads, use the -W flag.
+<ul>
+ <li>By itself, -W outputs the moves using the input text.
+ <li>Using -Whalg writes the moves in hyphenated long algebraic (e.g., e2-e4).
+ <li>Using -Wlalg writes the moves in long algebraic form (e.g., e2e4).
+ <li>Using -Welalg writes the moves in enhanced long algebraic form (e.g.,
+ Ne2e4, e5d6ep). The purpose of enhanced long algebraic form is to reduce the
+ amount of chess-specific knowledge that a post-procesing program might
+ need in order to interpret a chess game.
+ For instance, in order to provide a visualisation.
+ <li>Using -Wuci causes the moves of the game to be output in
+ a format that should close to being suitable for input to a
+ <a href="http://wbec-ridderkerk.nl/html/UCIProtocol.html">UCI-compatible</a> engine.
+ The output format is the same as with -Wlalg but all comments, NAGs,
+ variations, move numbers and checks removed.
+ In addition the whole game is output on a single line.
+</ul>
+
+<p>Output using non-English piece letters is possible using a variation
+of the -Wsan flag. This flag may have a six-letter suffix indicating
+the letters to be used in representing pawn, knight, bishop, rook,
+queen and king in game scores and diagrams. So:
+<pre>
+pgn-extract -WsanPNBRQK ...
+</pre>
+<p>would output in the (default) English notation, and
+<pre>
+pgn-extract -WsanBSLTDK ...
+</pre>
+<p>would output in German. Note that the letter for a pawn is required because
+board positions are sometimes output when an error is detected in
+a game score.
+
+<p>-Wepd outputs in EPD (Extended Position Description).
+A game is output as a sequence of EPD descriptions of
+the position at the start of the game, and following each move.
+Each EPD line contains the FEN board description, the active colour,
+castling availability and en passant target square. A c0 comment contains
+a synopsis of the player, event, site and date tags from the game's header.
+
+<p>-Wuci outputs in long-algebraic notation (-Wlalg) but also strips the
+game of everything apart from its moves, tags and result.
+It provides the equivalent of using the following multiple arguments:
+<pre>
+-Wlalg -C -N -V -w5000 --nomovenumbers --nochecks
+</pre>
+Use the --noresults and --notags options if tags and results are also
+to be removed.
+
+<p>-Wcm is an obsolete legacy flag and
+outputs the moves in what I believe to be (or used to be) ChessMaster format.
+
+<h2 id="-F">Forsyth-Edwards Notation (FEN) Descriptions (-F)</h2>
+<p>The -F flag provides a convenience method for generating
+a suitable FEN description of an arbitrary position.
+The -F flag causes pgn-extract to output a FEN description of the final
+position reached in a game, within the text of a comment.
+For instance, suppose you were interested in finding games that
+reach the position after the following moves.
+<pre>
+d4 Nf6 c4 e6 Nf3 b6 Nc3 Bb7 e3 Bb4 Bd3 O-O O-O Bxc3 bxc3 c5 *
+</pre>
+<p>Storing these moves in the file fen.pgn and running
+<pre>
+pgn-extract -F fen.pgn
+</pre>
+<p>would generate the score:
+<pre>
+[Event "?"]
+[Site "?"]
+[Date "????.??.??"]
+[Round "?"]
+[White "?"]
+[Black "?"]
+[Result "*"]
+
+1. d4 Nf6 2. c4 e6 3. Nf3 b6 4. Nc3 Bb7 5. e3 Bb4 6. Bd3 O-O 7. O-O Bxc3 8.
+bxc3 c5
+{ "rn1q1rk1/pb1p1ppp/1p2pn2/2p5/2PP4/2PBPN2/P4PPP/R1BQ1RK1/ w - c6 0 9" } *
+</pre>
+<p>The <a href="#-t">-t flag</a>
+makes it possible to use Forsyth-Edwards Notation (FEN) in the
+description of a position
+to be matched. For instance, the FEN string above
+could be cut and pasted to <a href="#-A">an argument file</a> and used with
+the <a href="#-t">-t flag</a> to supply matches:
+<pre>
+:-t
+FEN "rn1q1rk1/pb1p1ppp/1p2pn2/2p5/2PP4/2PBPN2/P4PPP/R1BQ1RK1/ w - c6 0 9"
+</pre>
+<p>See <a href="#fencomments">--fencomments</a> for the option to add
+a FEN comment after every move, including the final one.
+
+<h2 id="-z">Material Matches (-z)</h2>
+<p>The -z flag takes a filename of material balances for which you wish to
+search in games. The basic structure of the file is one or
+more lines of the form
+<pre>
+pieces1 pieces2
+</pre>
+<p>Pieces1 and pieces2 are lists of English piece letters for the material
+for the two sides that you wish to look for in a game.
+For instance:
+<pre>
+rp nb
+</pre>
+<p>looks for an game in which a lone Rook and Pawn for one side are
+competing against a lone Knight and Bishop for the other.
+
+<p>Text may be added after the piece lists as a form of comment.
+
+<p>A comment line may be placed in a material balance file by using a '%'
+as the first character of the line.
+
+<p>The <a href="#markmatches">--markmatches</a> flag may
+be used to add a comment at the point that the match is found.
+<p>The case of the
+letters is immaterial, there is no need to include Kings in the
+description, and the order of the pieces does not matter. Apart from
+Kings, if a piece letter is not listed for a side then that piece
+is not present within that side's material.
+A match will be tested for from both White and Black's point of view, so the
+example above matches the same games as:
+<pre>
+nb rp
+</pre>
+<p>Some notation may be added after any piece letter, typically to
+indicate something about the number of occurrences of that piece on one
+side.
+
+<p>The following are valid for each piece:
+<ul>
+ <li>* (zero or more of that piece).
+ <li>+ (one or more of that piece).
+ <li>d (exactly d occurrences of that piece, where d is a digit).
+ <li>d+ (d or more occurrences of that piece).
+ <li>d- (d or fewer occurrences of that piece).
+</ul>
+<p>So:
+<pre>
+QR2B2N2P8 QR2B2N2P8
+</pre>
+<p>is the starting material position, and QR+B*N*P7- represents material
+in which we require at least one pawn to be missing from one side and
+they should have a Queen and Rook, but we don't care about the minor
+pieces.
+
+<p>In addition, some extra notation is available to specify material
+relative to the opponent's.
+These are placed after the piece letter to which they refer.
+<ul>
+ <li>= (the number of these pieces must be the same as the opponent's).
+ <li># (the number of these pieces must be different the opponent's).
+ <li>> (the number of these pieces more than the opponent has).
+ <li>< (the number of these pieces less than the opponent has).
+</ul>
+<p>So,
+<pre>
+R+P+ R=P#
+</pre>
+<p>looks for Rook and Pawn games with an equal number of Rooks but
+unbalanced pawns.
+
+<p>In addition > and < may be preceded by a digit:
+<ul>
+ <li>d>
+ (the number of these pieces must be at least d more than the opponent's).
+ <li>d<
+ (the number of these pieces must be at least d less than the opponent's).
+</ul>
+<p>Two more notations, >=, <= may be preceded by an optional digit
+(the default is 1).
+The meaning of this may not be intuitively obvious and, to an extent, they
+represent a notational compromise.
+<ul>
+ <li>d>=
+ (the number of these pieces must be exactly d more than the opponent's).
+ <li>d<=
+ (the number of these pieces must be exactly d less than the opponent's).
+</ul>
+<p>In this example, both sides have a pair or Rooks but one has exactly one
+pawn more than the other:
+<pre>
+r2p* r=p1>=
+</pre>
+<p>Here is an example where one side has sacrificed a Rook and Pawn for
+Knight and Bishop and we don't care whether Queens are on or off the
+board, so long as they are balanced:
+<pre>
+q*r+n*b*p+ q=r<n>b>p1<
+</pre>
+<p>This example represents some of the imprecision that can occur with
+matches. The meaning of 'r<' is such that this could match positions
+in which one side as 2 Rooks and the other none. This can be corrected
+with:
+<pre>
+q*r+n*b*p+ q=r1<=n>b>p1<
+</pre>
+<p>enforcing strictly one Rook less. We ought also to correct the same
+problem with the minor pieces:
+<pre>
+q*r+n*b*p+ q=r1<=n1>=b1>=p1<
+</pre>
+<p>In practice, we probably want to allow general matching of minor pieces
+so the letter 'L' may be used to stand for a minor piece (Bishop or
+Knight). This example represents a similar sacrifice of Rook and Pawn for
+two minor pieces.
+<pre>
+q*r+l*p+ q=r1<=l2>=p1<
+</pre>
+<p>I would advise against mixing the minor piece letter with Knight and
+Bishop letters in the piece set for a single side, however, as I am not
+convinced that it will produce exact results.
+
+<ul>
+<li><p>Position Stability with -z<br />
+<p>The piece sets may be preceded by an optional number indicating the
+required stability of the position. Normally, if you are looking for a
+position with a particular set of material characteristics then you
+probably want that position to last for a reasonable number of moves in
+order to study its characteristics. The number before the piece sets is
+how many half-moves you wish that material balance to last. By default,
+this has a value of 2 so that fleeting positions in the middle of pairs
+of exchanges do not produce unwanted matches.
+This example looks for double-Rook and pawn games that last at least
+10 half-moves:
+<pre>
+10 R2P+ R=P*
+</pre>
+</ul>
+
+<h2 id="-7">The Seven Tag Roster (-7 or --seven)</h2>
+<p>This flag discards tag pairs that are not part of the Seven Tag
+Roster:
+<pre>
+Event, Site, Date, Round, White, Black and Result.
+</pre>
+<p>However, if the original game included a FEN tag, this is
+included in the output, as the moves will make no sense
+otherwise. In addition, if <a href="#-e">the -e flag</a> has been used for ECO
+classification, any ECO, Opening, Variation and SubVariation tags
+are also output.
+
+<h2 id="-R">User-defined Tag Roster Ordering (-R)</h2>
+<p>The -R flag makes it possible for to define the order in which
+tags for a game are listed in the output.
+The flag should be immediately followed by the name of a file
+that contains a list of tag names, one per line, for instance:
+<pre>
+pgn-extract -Rroster file.pgn
+</pre>
+<p>where roster might contain:
+<pre>
+% Output the tags of the seven tag roster alphabetically.
+Black
+Date
+Event
+Result
+Round
+Site
+White
+</pre>
+<p>The '%' character may be used to include comments in the file.
+Tags not listed in such a file will appear after the required
+tags have been output.
+
+<h2 id="evaluation">Include a position evaluation after each move (--evaluation)</h2>
+<p>The --evaluation argument causes a comment to be appended to every move,
+which contains an evaluation of the position immediately following that
+move.
+The default evaluation is a simplified version of
+<a href="http://en.wikipedia.org/wiki/Claude_Shannon">Shannon's board
+evaluation</a>. In this case, the evaluation is the difference between the
+value of White's position and Black's, where the value of a position is
+a weighted sum of the pieces plus a multiplier (0.1) applied to
+the number of available moves for that player.
+
+<p>I see this primarily as being a hook for people who wish to embed their
+own evaluations in the output.
+See the <code>evaluate</code> function in <code>apply.c</code> if you wish to
+write your own.
+
+<h2 id="fencomments">Include a comment with a FEN string for
+the position after each move (--fencomments)</h2>
+<p>The --fencomments argument causes a comment to be appended to every move,
+which contains a FEN string for the position immediately following that
+move. See <a href="#-F">-F</a> for adding a comment after just the
+final move.
+
+<h2 id="markmatches">Add a game comment on positional and material matches
+(--markmatches)</h2>
+<p>Add a game comment with the text immediately following --markmatches
+after the move which causes a positional or material match.
+For instance:
+<pre>
+pgn-extract -xvars --markmatches MATCH file.pgn
+</pre>
+<p>would add the comment <em>{ MATCH }</em> after every move that
+caused a match from the positional matches specified in the <em>vars</em> file.
+<p>See <a href="#-x">-x</a> for positional matches with moves,
+<a href="#fen-t">-t</a> for positional matches with FEN patterns,
+and <a href="#-z">-z</a> for material matches.
+
+<h2 id="addhashcode">Add a Tag containing a hashcode for the game (--addhashcode)</h2>
+<p>Add the tag HashCode to the tags. This contains a hashcode value
+generated from the moves of the game. Identical move sequences will
+produce the same hash code.
+
+<h2 id="totalplycount">Add a Tag containing the total ply count (--totalplycount)</h2>
+<p>Add the tag TotalPlyCount to the tags. This contains a count of
+the number of ply present in the game being output.
+Unless <a href="#suppress">variations have been suppressed</a> this will include
+all moves in variations as well as the main line.
+
+<h2 id="mailing">Mailing List</h2>

+
+<h2 id="limitations">Limitations</h2>
+<p>The moves, variations, and commentary of each game are held internally
+and reformatted when a game is extracted, rather than reproducing the
+original text of the game source.
+
+<p>Lower-case 'b' as the first character of a move is taken to be a move
+of the b-pawn if one to match the move can be found. Otherwise, Bishop
+moves are tried as an alternative. There is no back-up on failure if
+picking a valid pawn move was the wrong choice.
+
+<p>Lower-case 'b' as the first character of a Bishop move is not
+acceptable in the variations files.
+
+<p>Duplicate detection is not guaranteed to be exact.
+The -Z flag has slightly more potential to avoid false duplicates
+as it compares separate values for the end position and move sequence,
+whereas these are XORed to save space when -Z is not used.
+However, this will only make a difference and avoid false
+matches if
+two different games at the same hashtable index
+also produce identical XORed values.
+
+<p>The results of the -x, -v, and -t/-T search criteria are AND-ed
+together. There might be occasions when you wanted to search for games
+that matched either positional variations or textual variations at the
+same time, for instance. This requires multiple runs of pgn-extract.
+
+<p>The -Wsan variation that allows selection of the output language
+is tied to single-character piece descriptions. This does
+not support Russian usage, for instance, in which the King
+is described as a character pair.
+
+<h2 id="files">The Files</h2>

+<p>pgn-extract is regularly used under Windows/DOS
+(using <a href="http://www.mingw.org/">Minimalist
+GNU for Windows</a>),
+and various versions of Linux and Mac OSX.
+
+<h2 id="acknowledgements">Acknowledgements</h2>
+<p>I would like to thank all those who used the program and made
+suggestions for things to add. In particular, thanks to Michael Kerry
+whose help led to better determination of game boundaries in earlier
+versions, and V. Armando Sole whose own filter
+program was the inspiration for adding textual variation permutations.
+John Brogan suggested adding the ! notation to the variation file and
+provided the spur for duplicate detection.
+He also supplied the original code for soundex matching (-S).
+<p>Jaroslav Poriz, Ron Leamon, Ed Leonard, Charles
+Frohman, and Robert Wilhelm helped with testing at various times.
+Bernhard Maerz was instrumental in encouraging the inclusion of ECO
+classification and material balance matches.
+He and Peter Otterstaetter
+suggested the relational operators in tag files, with Peter also
+providing the spur to make duplicate detection work with bigger game files
+(-Z) and doing some very useful testing for me.
+<p>Kayvan Sylvan requested
+long algebraic output and identified an error in ECO classification.
+Cameron Hayne suggested matching on the number of moves in a game.
+Owen D. Lyne suggested extension of the -E flag,
+and both tested and provided diagnostic data to help refine the
+ECO classification aspects of the program.
+Karl-Martin Skontorp provided the incentive and testing help that
+enabled me to add the -Wepd option.
+<p>FEN pattern matching is based on pattern matching code by Rob Pike.
+Taken from:
+http://www.cs.princeton.edu/courses/archive/spr09/cos333/beautiful.html
+and ideas from Kernighan and Plauger's "Software Tools".
+<p>Finally, thanks, of course, to Steven Edwards
+for his work on developing the PGN standard.

+<h2>Introduction</h2>
+<p>This is the home page for
+the <em>pgn-extract</em> program,
+which is a <em>command-line</em> program for manipulating
+chess games recorded in the Portable Game Notation (PGN).
+<p>A <a href="http://www.cs.kent.ac.uk/people/staff/djb/pgn-extract/help.html">full
+description of pgn-extract's functionality</a> is available and included
+with the sources.
+
+<p>Here you can find the C source code and win32 binary for the current
+version.
+pgn-extract compiles and runs under Windows, Linux and Mac OSX.
+This program is made available under the terms of the
+<a href="ftp://ftp.cs.kent.ac.uk/pub/djb/pgn-extract/COPYING">GNU
+General Public License (Version 1).</a>
+
+<h2>Overview</h2>
+<p>The program is designed to make it easy to extract selected games from a
+PGN format data file based on a wide variety of criteria.
+The criteria include:
+<ul>
+<li><p>textual move sequences;</p></li>
+<li><p>the position reached after a sequence of moves;</p></li>
+<li><p>information in the tag fields;</p></li>
+<li><p>fuzzy board position;</p></li>
+<li><p>and material balance in the ending.</p></li>
+</ul>
+<p>The program includes a semantic analyser which will
+report errors in game scores and it is also able to detect duplicate
+games found in its input files.
+
+<p>The range of input move formats accepted is fairly wide and includes
+recognition of lower-case piece letters for English and upper-case
+piece letters for Dutch and German. The output is normally in English Standard
+Algebraic Notation (SAN), but this can be varied.
+
+<p>Extracted games may be written out either including or excluding
+comments, NAGs, variations, move numbers, tags and/or results.
+Games may be given ECO classifications
+derived from the accompanying file eco.pgn, or a customised version
+provided by the user.
+
+<p>The program is designed to be relatively memory-friendly, so it
+does not retain a game's moves in memory once it has been processed.
+
+<p>Use the <em>--help</em> argument to the program to
+get the full lists of arguments.
+
+<h2>New in version 17-1x</h2>
+<p>These are the major additions in version 17-1x:
+<ul>
+ <li><p>Null moves (--) in variations now recognised.
+ This is non-standard PGN notation.
+ Note that there is scope for semantic errors here, so please let me know
+ if you come across any game scores containing null moves that
+ pgn-extract does not deal with
+ correctly.
+ <li><p>v17-14 corrected a long-standing error in the whole-move number
+ in FEN output.
+ <li><p><a href="help.html#fuzzydepth">--fuzzydepth flag</a>
+ allows duplicate detection based on position reached
+ at a particular ply depth.
+ <li><p><a href="help.html#-W">-Wuci</a> outputs a game in a format suitable for input to
+ a <a href="http://wbec-ridderkerk.nl/html/UCIProtocol.html">UCI-compatible</a> engine.
+ <li><p>Board position matches with <a href="help.html#fen-t">the -t flag</a> that
+ allow fuzzy board position matches.
+ <li><p>A test suite of the program's basic functionality to support
+ regression testing. This won't be of interest to users but might be
+ to developers.
+</ul>
