Increase reductions with thread count Respin of multi-thread idea that was simplified away recently: basically doing more reductions with thread count since Lazy SMP naturally widens search. With drawish book this idea got simplified away but with less drawish book it again gains elo, maybe trying to reinstall other ideas that were simplified away previously can be beneficial. passed STC LLR: 2.96 (-2.94,2.94) <-0.50,2.50> Total: 39736 W: 10205 L: 9986 D: 19545 Ptnml(0-2): 45, 4254, 11064, 4447, 58 https://tests.stockfishchess.org/tests/view/615750702d02f48db3961b00 passed LTC LLR: 2.97 (-2.94,2.94) <0.50,3.50> Total: 60352 W: 15530 L: 15218 D: 29604 Ptnml(0-2): 24, 5900, 18016, 6212, 24 https://tests.stockfishchess.org/tests/view/6157d8935488e26ea5eace7f closes https://github.com/official-stockfish/Stockfish/pull/3724 Bench 5714575
