King proximity tweak for passed pawns Decrease slightly the penalty for opponent king distance to passed pawn. Instead of 5:2 ratio (or 20:8) we now have 19:8 STC http://tests.stockfishchess.org/tests/view/5de281b2727dc1d26718a673 LLR: 2.95 (-2.94,2.94) [-1.50,4.50] Total: 28638 W: 6297 L: 6104 D: 16237 LTC http://tests.stockfishchess.org/tests/view/5de2a2ff727dc1d26718a67b LLR: 2.95 (-2.94,2.94) [0.00,3.50] Total: 59586 W: 9766 L: 9429 D: 40391 Where to go from here: Further tests will try a similar tweak on the friendly king proximity penalty, because recent experiments indicate that this penalty is quite sensitive, but I wanted to try first on the larger term. Closes https://github.com/official-stockfish/Stockfish/pull/2435 bench: 5258928 --------------- Increasing the penalty ratio to 21:8 was neutral. http://tests.stockfishchess.org/tests/view/5de2814d727dc1d26718a671 Decreasing the penalty ratio a bit more to 9:4 seems less promising http://tests.stockfishchess.org/tests/view/5de2f4c2727dc1d26718a691 http://tests.stockfishchess.org/tests/view/5de32ecc727dc1d26718a6b0
