Simplify condition for ProbCut move count pruning We retire depth-dependence in ProbCut move count pruning, the move count limit condition is now : "probCutCount < 3" STC: LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 33895 W: 6995 L: 6897 D: 20003 http://tests.stockfishchess.org/tests/view/5aa6eaba0ebc59029781009d LTC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 28959 W: 4441 L: 4333 D: 20185 http://tests.stockfishchess.org/tests/view/5aa73dfa0ebc5902978100be Ideas for future work: • Is a flat move count limit in ProbCut ideal? Depth dependence, or dependence on some other variable, could possibly be reintroduced. • The move count limit 3 is untuned and a better value may exist. Closes https://github.com/official-stockfish/Stockfish/pull/1486 Bench: 5741807
