Increase reduction for captures. The idea behind this patch is that if static eval is really bad so capturing of current piece on spot will still produce a position with an eval much lower than alpha then our best chance is to create some kind of king attack. So captures without check are mostly worse than captures with check and can be reduced more. passed STC https://tests.stockfishchess.org/tests/view/5e8514b44411759d9d098543 LLR: 2.94 (-2.94,2.94) {-0.50,1.50} Total: 46196 W: 9039 L: 8781 D: 28376 Ptnml(0-2): 750, 5412, 10628, 5446, 862 passed LTC https://tests.stockfishchess.org/tests/view/5e8530134411759d9d09854c LLR: 2.94 (-2.94,2.94) {0.25,1.75} Total: 23462 W: 3228 L: 2988 D: 17246 Ptnml(0-2): 186, 2125, 6849, 2405, 166 close https://github.com/official-stockfish/Stockfish/pull/2612 bench 4742598
