Remove goto, limit skipping to NMP This patch simplifies the control flow in search(), removing an if and a goto. A side effect of the patch is that Stockfish is now a little bit more selective at low depths, because we allow razoring, futility pruning and probcut pruning after a null move. passed STC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 32035 W: 6523 L: 6422 D: 19090 passed LTC: LLR: 2.95 (-2.94,2.94) [-3.00,1.00] Total: 41431 W: 6187 L: 6097 D: 29147 Ideas for further work: • Use the nodes credit opened by the patch (the increased selectivity) to try somewhat higher razoring, futility or probcut margins at [0..4].
