Tweak capture scoring for move ordering Move divisor from capture scoring to good capture check and sligthly increase it. This has several effects: - its a speedup because for quience and probcut search the division now never happens. For main search its delayed and can be avoided if a good capture triggers a cutoff - through the higher resolution of scores we have a more granular sorting STC: https://tests.stockfishchess.org/tests/view/65bf2a93c865510db027dc27 LLR: 2.93 (-2.94,2.94) <0.00,2.00> Total: 470016 W: 122150 L: 121173 D: 226693 Ptnml(0-2): 2133, 55705, 118374, 56644, 2152 LTC: https://tests.stockfishchess.org/tests/view/65c1d16dc865510db0281339 LLR: 2.96 (-2.94,2.94) <0.50,2.50> Total: 98988 W: 25121 L: 24667 D: 49200 Ptnml(0-2): 77, 10998, 26884, 11464, 71 closes https://github.com/official-stockfish/Stockfish/pull/5036 Bench: 1233867
