Date: Thu Apr 15 12:45:39 2021 +0200 Timestamp: 1618483539 Use classical eval for Bishop vs Pawns NNUE evaluation is incapable of recognizing trivially drawn bishop endgames (the wrong-colored rook pawn), which are in fact ubiquitous and stock standard in chess analysis. Switching off NNUE evaluation in KBPs vs KPs endgames is a measure that stops Stockfish from trading down to a drawn version of these endings when we presumably have advantage. The patch is able to edge over master in endgame positions. Patch tested for Elo gain with the "endgame.epd" book, and verified for non-regression with our usual book (see the pull request for details).

Date: Sun Mar 7 21:16:38 2021 +0100 Timestamp: 1615148198 Use Bitboard over Square in movegen It uses pos.checkers() on target when movegen is the type of EVASION. It simplify the code. And it's also expected a slightly speed up, because Bitboard is more direct when doing bitwise.
