Subject: A move needs 17 bits not 19
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=9e44a6dba9718b74a64656ae7801a62946c3b725;hp=9e44a6dba9718b74a64656ae7801a62946c3b725

A move needs 17 bits not 19

Fix a bug in the way a move is stored and read in a TT entry.
We use a mask of 19 bits insteaad of 17 so that the last
two bits in the TT entry end up to be random data.

This bug will bite us when we will use these two until now
unused bits.
