Don't special case for abs(beta) >= VALUE_MATE_IN_MAX_PLY Remove from the search this special case and apply null search and razoring also in mate positions. Tested in no-regression mode and passed both STC LLR: 2.96 (-2.94,2.94) [-3.00,1.00] Total: 65431 W: 10860 L: 10810 D: 43761 and LTC LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 34928 W: 4814 L: 4713 D: 25401 This patch kicks in only in mate positions and in these cases it seems beneficial in finding mates faster as Yery Spark measured on the Chest mate suite: Total number of positions 6425 Fixed nodes 200K per position master: 1049 new: 1154 And also the 5446 'hard' positions again with 2000K nodes (those not found by both engines in 200K nodes): master: 1069 new: 1395 bench: 7710548
