This patch lines up with other patches which use better eval to produce more aggressive cutoffs based on static evaluation of position, it allows more aggressive futility pruning for captures - so now we will be producing them with bigger evaluation of position, so more often. passed STC https://tests.stockfishchess.org/tests/view/5f2da79e61e3b6af64881fd2 LLR: 3.87 (-2.94,2.94) {-0.50,1.50} Total: 27256 W: 3809 L: 3593 D: 19854 Ptnml(0-2): 221, 2578, 7830, 2762, 237 passed LTC https://tests.stockfishchess.org/tests/view/5f2df92061e3b6af64882012 LLR: 4.97 (-2.94,2.94) {0.25,1.75} Total: 43624 W: 3095 L: 2820 D: 37709 Ptnml(0-2): 66, 2410, 16608, 2639, 89 closes official-stockfish/Stockfish#2946 Bench: 4272280
