Dev Builds » 20210211-2239

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.

PV-Nodes likely to fail low Do not decrease reduction at pv-nodes which are likely to fail low. The idea of this patch can be described as following: during the search, if a node on the principal variation was re-searched in non-pv search and this re-search got a value which was much lower than alpha, then we can assume that this pv-node is likely to fail low again, and we can reduce more aggressively at this node.
