Instead, skip early pruning only when there is an excluded move, and try null move pruning only if the previous move was not itself a null move. passed STC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 33623 W: 6853 L: 6755 D: 20015 http://tests.stockfishchess.org/tests/view/5aef462a0ebc5902a409a10e passed LTC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 39474 W: 5882 L: 5789 D: 27803 http://tests.stockfishchess.org/tests/view/5aefd4b80ebc5902a409a164 Closes https://github.com/official-stockfish/Stockfish/pull/1585 Bench: 4953556
