Reduce repetitions branches Increase reduction on retrying a move we just retreated that falls in a repetition: if current move can be the same move from previous previous turn then we retreated that move on the previous turn, this patch increases reduction if retrying that move results in a repetition. How to continue from there? Maybe we some variants of this idea could bring Elo too (only testing the destination square, or triangulations, etc.) Passed STC: https://tests.stockfishchess.org/tests/view/64e1aede883cbb7cbd9ad976 LLR: 2.94 (-2.94,2.94) <0.00,2.00> Total: 424000 W: 108675 L: 107809 D: 207516 Ptnml(0-2): 1296, 47350, 113896, 48108, 1350 Passed LTC: https://tests.stockfishchess.org/tests/view/64e32d629970091252666872 LLR: 2.94 (-2.94,2.94) <0.50,2.50> Total: 89682 W: 22976 L: 22569 D: 44137 Ptnml(0-2): 39, 8843, 26675, 9240, 44 closes https://github.com/official-stockfish/Stockfish/pull/4757 bench: 1574347
