Dev Builds » 20200325-2042

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.

Remove KNPKB endgame. This is a functional simplification that removes the KNPKB endgame. Testing on only KNPKB positions suggests that this removal actually gains Elo: Score of patch vs master: 3380 - 3035 - 33585 [0.504] 40000 Elo difference: 3.0 +/- 1.4, LOS: 100.0 %, DrawRatio: 84.0 % Score of patch vs master: 290 - 36 - 39674 [0.503] 40000 Elo difference: 2.2 +/- 0.3, LOS: 100.0 %, DrawRatio: 99.2 % removal also doesn't cause a regression with the standard book: STC LLR: 2.95 (-2.94,2.94) {-1.50,0.50} Total: 71376 W: 13794 L: 13719 D: 43863 Ptnml(0-2): 1066, 8092, 17290, 8181, 1059 https://tests.stockfishchess.org/tests/view/5e76c3d5e42a5c3b3ca2e8be LTC LLR: 2.95 (-2.94,2.94) {-1.50,0.50} Total: 28394 W: 3731 L: 3662 D: 21001 Ptnml(0-2): 167, 2339, 9116, 2408, 167 https://tests.stockfishchess.org/tests/view/5e76e5eae42a5c3b3ca2e8d3 closes https://github.com/official-stockfish/Stockfish/pull/2594 Bench 5480811
