Prune illegal moves in qsearch earlier The main idea is that illegal moves influencing search or qsearch obviously can't be any sort of good. The only reason why initially legality checks for search and qsearch were done after they actually can influence some heuristics is because legality check is expensive computationally. Eventually in search it was moved to the place where it makes sure that illegal moves can't influence search. This patch shows that the same can be done for qsearch + it passed STC with elo-gaining bounds + it removes 3 lines of code because one no longer needs to increment/decrement movecount on illegal moves. passed STC with elo-gaining bounds https://tests.stockfishchess.org/tests/view/60f20aefd1189bed71812da0 LLR: 2.94 (-2.94,2.94) <-0.50,2.50> Total: 61512 W: 4688 L: 4492 D: 52332 Ptnml(0-2): 139, 3730, 22848, 3874, 165 The same version functionally but with moving condition ever earlier passed LTC with simplification bounds. https://tests.stockfishchess.org/tests/view/60f292cad1189bed71812de9 LLR: 2.98 (-2.94,2.94) <-2.50,0.50> Total: 60944 W: 1724 L: 1685 D: 57535 Ptnml(0-2): 11, 1556, 27298, 1597, 10 closes https://github.com/official-stockfish/Stockfish/pull/3618 bench 4709569
