Dev Builds » 20200123-1631

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.

Simplify signature of remove_piece() This is a non-functional simplification. Instead of passing the piece type for remove_piece, we can rely on the board. The only exception is en-passant which must be explicitly set because the destination square for the capture is not the same as the piece to remove. Verified also in the Chess960 castling case by running a couple of perft, see the pull request discussion: https://github.com/official-stockfish/Stockfish/pull/2460 STC LLR: 2.94 (-2.94,2.94) [-3.00,1.00] Total: 18624 W: 4147 L: 4070 D: 10407 Ptnml(0-2): 223, 1933, 4945, 1938, 260 http://tests.stockfishchess.org/tests/view/5dfeaa93e70446e17e451163 No functional change
