Dev Builds » 20121030-1927

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.

Commit ID	fe1cbe26383085a44809d56493d29ce9c1815aa8
Author	Marco Costalba

Use correct occupancy in connected_threat() When checking if a move defends the threatened piece we correctly remove from the occupancy bitboard the moved piece. This patch removes from the occupancy also the threatening piece so to consider the cases of moves that defend the threatened piece x-raying through the threat move. As example in this position: r3k2r/p1ppqp2/Bn4p1/3p1n2/4P1N1/5Q1P/PPP2P1P/R3K2R w KQkq - 1 10 The threat black move is dxe4. With this patch we include (and so don't prune) white's Bb7 that would be pruned otherwise. The number of affected position is very low, around 1% of cases, so we don't expect ELO changes, neverthless this is the logical and natural thing to do. Patch suggested by Hongzhicheng. new bench: 5323798
