Dev Builds » 20200415-1833

You are viewing an old NCM Stockfish dev build test. You may find the most recent dev build tests using Stockfish 15 as the baseline here.

Use this dev build

NCM plays each Stockfish dev build 20,000 times against Stockfish 7. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

Don't attempt probcut if ttMove is not good enough. This idea is loosely based on xoroshiro idea about raisedBeta and ttmoves. If our ttmove have low enough ttvalue and is deep enough (deeper than our probcut depth) it makes little sense to try probcut moves, since the ttMove already more or less failed to produce one according to transposition table. passed STC https://tests.stockfishchess.org/tests/view/5e9673ddc2718dee3c822920 LLR: 2.95 (-2.94,2.94) {-0.50,1.50} Total: 72148 W: 14038 L: 13741 D: 44369 Ptnml(0-2): 1274, 8326, 16615, 8547, 1312 passed LTC https://tests.stockfishchess.org/tests/view/5e96b378c2718dee3c8229bf LLR: 2.94 (-2.94,2.94) {0.25,1.75} Total: 89054 W: 11418 L: 10996 D: 66640 Ptnml(0-2): 623, 8113, 26643, 8515, 633 closes https://github.com/official-stockfish/Stockfish/pull/2632 bench 4952731
