Dev Builds » 20210220-2149

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.

Introduce ProbCut for check evasions The idea of this patch can be described as follows: if we are in check and the transposition table move is a capture that returns a value far above beta, we can assume that the opponent just blundered a piece by giving check, and we return the transposition table value. This is similar to the usual probCut logic for quiet moves, but with a different threshold.
