Scale down complexity for almost unwinnable endgames This patch greatly scales down complexity of endgames when the following conditions are all true together: - pawns are all on one flank - stronger side king is not outflanking weaker side - no passed pawns are present This should improve stockfish evaluation of obvious draws 4 vs 3, 3 vs 2 and 2 vs 1 pawns in rook/queen/knight/bishop single flank endgames where strong side can not make progress. passed STC LLR: 2.94 (-2.94,2.94) [0.50,4.50] Total: 15843 W: 3601 L: 3359 D: 8883 passed LTC LLR: 2.96 (-2.94,2.94) [0.00,3.50] Total: 121275 W: 20107 L: 19597 D: 81571 Closes https://github.com/official-stockfish/Stockfish/pull/2298 Bench: 3954190 ========================== How to continue from there? a) This could be a powerful idea for refining some parts of the evaluation function, a bit like when we try quadratics or other equations to emphasize certain situations (xoto10). b) Some other combinaison values for this bonus can be done further, or overall retuning of weight and offset while keeping the formula simple.
