Tweak opposite colord bishops endgame scaling. Make scale factor dependant on asymmetry of pawn structure. STC http://tests.stockfishchess.org/tests/view/5b92a2a80ebc592cf2753dd4 LLR: 2.96 (-2.94,2.94) [0.00,5.00] Total: 31490 W: 6870 L: 6587 D: 18033 LTC http://tests.stockfishchess.org/tests/view/5b92f8170ebc592cf2754438 LLR: 2.95 (-2.94,2.94) [0.00,5.00] Total: 54928 W: 8988 L: 8653 D: 37287 This patch shows that SF can use some more complicated endgame heuristics to evaluate endgames better from the distance.
