Dev Builds » 20220205-0640

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.

Reintroduce razoring Razoring was simplified away some years ago, this patch reintroduces it in a slightly different form. Now for low depths if eval is far below alpha we check if qsearch can push it above alpha - and if it can't we return a fail low. passed STC https://tests.stockfishchess.org/tests/view/61fbf968d508ec6a1c9f3274 LLR: 2.94 (-2.94,2.94) <0.00,2.50> Total: 226120 W: 61106 L: 60472 D: 104542 Ptnml(0-2): 1118, 25592, 59080, 26078, 1192 passed LTC https://tests.stockfishchess.org/tests/view/61fcc569d508ec6a1c9f5617 LLR: 2.94 (-2.94,2.94) <0.50,3.00> Total: 113128 W: 30851 L: 30397 D: 51880 Ptnml(0-2): 114, 11483, 32926, 11917, 124 closes https://github.com/official-stockfish/Stockfish/pull/3921 bench 4684080
