Tweak null move pruning conditions Allow null move pruning only if last stat score < 30000. Passed STC: LLR: 2.95 (-2.94,2.94) [0.00,5.00] Total: 12653 W: 2641 L: 2454 D: 7558 http://tests.stockfishchess.org/tests/view/5af1d8830ebc5968e6523edb Passed LTC: LLR: 2.97 (-2.94,2.94) [0.00,5.00] Total: 19782 W: 3072 L: 2878 D: 13832 http://tests.stockfishchess.org/tests/view/5af1ee8c0ebc5968e6523ee4 Ideas for further work: • Tune the stat score threshold. • Try depth based stat score threshold. • Try stat score condition for other prunings.
