Dev Builds » 20200521-1205

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.

A combo of parameters tweaks This patch is a combinaison of two recent parameters tweaks which had failed narrowly (yellow) at long time control: • improvement in move ordering during search by softening the distinction between bad captures and good captures during move generation, leading to improved awareness of Stockfish of potential piece sacrifices (idea by Rahul Dsilva) • increase in the weight of pawns in the "initiative" part of the evaluation function. With this change Stockfish should have more incentive to exchange pawns when losing, and to keep pawns when winning.
