Dev Builds » 20230313-2341

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 14. This yields an approximate Elo difference and establishes confidence in the strength of the dev builds.

More negative extensions on nonsingular nonpv nodes. Following up the previous gainer also in this nonsingular node section of code. Credit shared with @FauziAkram for realizing this nonsingular node stuff had some potential, and @XInTheDark for reminding us that !PvNodes better handle extensions/reductions than Pv.
