Dev Builds » 20210925-2012

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.

Reduction instead of cutoff In master, during singular move analysis, when both the transposition value and a reduced search for the other moves seem to indicate a fail high, we heuristically prune the whole subtree and return an fail high score. This patch is a little bit more cautious in this case, and instead of the risky cutoff, we now search the ttMove with a reduced depth (by two plies).
