Subject: Add checkers info to Position::pretty()
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=e9ab7353de074a0a970d334ac98b391e2222f77d

Add checkers info to Position::pretty()

In case current position is under check, list the
squares of the checker(s) pieces.

This should satisfy a specific user request.

No functional change.
