Simplify LMR rule for non-checking captures We simplify away the complicated rule in LMR for "non-checking captures likely to be bad", as it seems not to bring any strength anymore. STC: LLR: 2.94 (-2.94,2.94) <-2.50,0.50> Total: 55256 W: 4972 L: 4897 D: 45387 Ptnml(0-2): 177, 3976, 19234, 4077, 164 https://tests.stockfishchess.org/tests/view/609adf3b3a33eb67a844f842 LTC: LLR: 2.95 (-2.94,2.94) <-2.50,0.50> Total: 10344 W: 437 L: 353 D: 9554 Ptnml(0-2): 1, 322, 4449, 392, 8 https://tests.stockfishchess.org/tests/view/609b3dfa3a33eb67a844f88e -- While at it, we also update the Elo estimate of the previous rule in LMR (see https://tests.stockfishchess.org/tests/view/609af2a63a33eb67a844f867). closes https://github.com/official-stockfish/Stockfish/pull/3460 Bench: 3840688
