Author: Stéphane Nicolet Date: Sun Sep 25 10:45:10 2016 +0200 Timestamp: 1474793110 Rename shift_bb() to shift() Rename shift_bb() to shift(), and DELTA_S to SOUTH, etc. to improve code readability, especially in evaluate.cpp when they are used together: old b = shift_bb<DELTA_S>(pos.pieces(PAWN)) new b = shift<SOUTH>(pos.pieces(PAWN)) While there fix some small code style issues. No functional change.

Spotted and reported by Dann Corbit. Added some mate/stalemate positions to bench so to early catch this regression in the future. No functional change.

Author: Stéphane Nicolet Date: Thu Sep 22 08:31:23 2016 +0200 Timestamp: 1474525883 Simplify pinners conditions in SEE() Use the following transformations: - to check that A is included in B, testing "(A & ~B) == 0" is faster than "(A & B) == A" - to remove the intersection of A and B from A, doing "A &= ~B;" is as fast as "if (A & B) A &= ~B;" but is simpler. Overall, the simpler patch version is 0.3% than current master. No functional change.

With this patch 'pinners' only returns sliders with exactly one defensive piece between the slider and the attacked square (in other words, pinners returns exact pinners).
