Qsearch pruning: follow-up This is a follow-up of the recent qsearch pruning patch in https://github.com/official-stockfish/Stockfish/commit/a260c9a8a24a2630a900efc3821000c3481b0c5d We now use the same guard condition (testing that we already have a defense with a score better score than a TB loss) for all pruning heuristics in qsearch(). This allows some pruning when in check, but in a controlled way to ensure that no wrong mate scores appear. Tested with Elo-gaining bounds: STC: LLR: 2.97 (-2.94,2.94) {-0.25,1.25} Total: 22632 W: 2433 L: 2264 D: 17935 Ptnml(0-2): 98, 1744, 7487, 1865, 122 https://tests.stockfishchess.org/tests/view/5fa59405936c54e11ec99515 LTC: LLR: 2.94 (-2.94,2.94) {0.25,1.25} Total: 105432 W: 4965 L: 4648 D: 95819 Ptnml(0-2): 85, 4110, 44011, 4423, 87 https://tests.stockfishchess.org/tests/view/5fa5b609936c54e11ec9952a closes https://github.com/official-stockfish/Stockfish/pull/3221 Bench: 3578092
