Stockfish - UCI chess engine, i nteresting compiled by  Vizvezdenec Do lmr for more captures  Based on machinery introduced by vondele. Logic behind patch if relatively simple -  if we reduce less with high hit rate of transposition table somewhat logical is to  reduce more with low hit rate. For example enable all captures for LMR.  Threshold 0.375 is arbitrary and can be tweaked :)  STC  LLR: 2.97 (-2.94,2.94) [-1.50,4.50]  Total: 16495 W: 3591 L: 3434 D: 9470 Elo +3.31 LTC  LLR: 2.96 (-2.94,2.94) [0.00,3.50]  Total: 23598 W: 3956 L: 3716 D: 15926 Elo +3.53 Rating JCER=3257 Stockfish 19112109 - download
