Dev Builds » 20220220-2201

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.

Adjust usage of LMR for 2nd move in move ordering Current master prohibits usage of LMR for 2nd move at rootNode. This patch also disables LMR for 2nd move not only at rootNode but also at first PvNode that is a reply to rootNode. passed STC: https://tests.stockfishchess.org/tests/view/620e8c9026f5b17ec885143a LLR: 2.94 (-2.94,2.94) <0.00,2.50> Total: 54096 W: 14305 L: 13996 D: 25795 Ptnml(0-2): 209, 6075, 14192, 6342, 230 passed LTC: https://tests.stockfishchess.org/tests/view/620eb327b1792e8985f81fb8 LLR: 2.94 (-2.94,2.94) <0.50,3.00> Total: 110864 W: 29602 L: 29156 D: 52106 Ptnml(0-2): 112, 11147, 32455, 11619, 99 closes https://github.com/official-stockfish/Stockfish/pull/3940 bench 6820724
