Dev Builds » 20160912-0731

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.

Notice: NCM upgraded all servers to to Ubuntu 18.04 (from 16.04) on October 23rd. Binaries compiled on the upgraded disto are skewing measurements upwards. We are working on a fix.

Pinned aware SEE

Don't allow pinned pieces to attack the exchange-square as long all
pinners (this includes also potential ones) are on their original
square.
As soon a pinner moves to the exchange-square or get captured on it, we
fall back to standard SEE behaviour.

This correctly handles the majority of cases with absolute pins.
