Do more futility pruning for parent nodes. This patch increases LMRdepth threshold for futility pruning at parent nodes so it can apply more often. With radical change to evaluation approach it seems that search is really far from optimal state, especially it parts that use static evaluation of position. passed STC https://tests.stockfishchess.org/tests/view/5f2da75661e3b6af64881fd0 LLR: 2.93 (-2.94,2.94) {-0.50,1.50} Total: 8744 W: 1305 L: 1156 D: 6283 Ptnml(0-2): 75, 789, 2500, 928, 80 passed LTC https://tests.stockfishchess.org/tests/view/5f2dcb2a61e3b6af64881ff3 LLR: 2.98 (-2.94,2.94) {0.25,1.75} Total: 17728 W: 1256 L: 1117 D: 15355 Ptnml(0-2): 22, 961, 6774, 1070, 37 Bench: 4067325
