Apply good/bad history reduction also when inCheck Main idea is that, in some cases, 'in check' situations are not so different from 'not in check' ones. Trying to use piece count in order to select only a few 'in check' situations have failed LTC testing. It could be interesting to apply one of those ideas in other parts of the search function. passed STC: https://tests.stockfishchess.org/tests/view/60f1b68dd1189bed71812d40 LLR: 2.93 (-2.94,2.94) <-2.50,0.50> Total: 53472 W: 4078 L: 4008 D: 45386 Ptnml(0-2): 127, 3297, 19795, 3413, 104 passed LTC: https://tests.stockfishchess.org/tests/view/60f291e6d1189bed71812de3 LLR: 2.92 (-2.94,2.94) <-2.50,0.50> Total: 89712 W: 2651 L: 2632 D: 84429 Ptnml(0-2): 60, 2261, 40188, 2294, 53 closes https://github.com/official-stockfish/Stockfish/pull/3619 Bench: 5185789
