Since it's already capped by margin that is a function of lmrDepth there is no need to extra cap it with lmrDepth. passed STC https://tests.stockfishchess.org/tests/view/60e9b5dfd1189bed71812777 LLR: 2.97 (-2.94,2.94) <-2.50,0.50> Total: 14872 W: 1264 L: 1145 D: 12463 Ptnml(0-2): 37, 942, 5369, 1041, 47 passed LTC https://tests.stockfishchess.org/tests/view/60e9c635d1189bed71812790 LLR: 2.96 (-2.94,2.94) <-2.50,0.50> Total: 40336 W: 1280 L: 1225 D: 37831 Ptnml(0-2): 24, 1057, 17960, 1094, 33 closes https://github.com/official-stockfish/Stockfish/pull/3612 bench: 5064969
