Try nullmoves only on cutnodes since master only tries nullmoves on cutNodes already with 99.0224% of the cases running bench, We can try null moves at 100% of cutNodes and achieve such simplification, by making passing false already equivalent to passing !cutNode This is a more correct form of PR #5482 Passed non-regression STC: https://tests.stockfishchess.org/tests/view/66941c044ff211be9d4ebf5f LLR: 2.93 (-2.94,2.94) <-1.75,0.25> Total: 153216 W: 39856 L: 39764 D: 73596 Ptnml(0-2): 590, 18174, 38979, 18284, 581 Passed non-regression LTC: https://tests.stockfishchess.org/tests/view/6694e5cd4ff211be9d4ebfdf LLR: 2.94 (-2.94,2.94) <-1.75,0.25> Total: 67842 W: 17178 L: 17004 D: 33660 Ptnml(0-2): 52, 7437, 18759, 7631, 42 closes https://github.com/official-stockfish/Stockfish/pull/5490 bench: 1345400 Co-Authored-By: FauziAkram <11150271+fauziakram@users.noreply.github.com>
