Authors: Marco Costalba, Joona Kiiski, Stockfish team members Links: List of Authors, Homepage, Development Versions, Testing Framework
Stockfish was originally based on Glaurung by Tord Romstad. On our blitz list, this includes games from the Stockfish development version 2021-02-11 (Date: Thu Feb 11 23:39:06 2021 +0100 Timestamp: 1613083146). We tested this version, which subsequently had no further functional changes to it and essentially became Stockfish 13. On our 40/15 list, this includes a small number of games from the development version of 2021-02-16. We tested this version, which subsequently had no further functional changes to it and essentially became Stockfish 13.
This is one of the 72 Stockfish versions we tested: Compare them!
