Stockfish 14.1 Official release version of Stockfish 14.1 Bench: 6334068 --- Today, we have the pleasure to announce Stockfish 14.1. As usual, downloads will be freely available at stockfishchess.org/download [1]. With Stockfish 14.1 our users get access to the strongest chess engine available today. In the period leading up to this release, Stockfish convincingly won several chess engine tournaments, including the TCEC 21 superfinal, the TCEC Cup 9, and the Computer Chess Championship for Fischer Random Chess (Chess960). In the latter tournament, Stockfish was undefeated in 599 out of 600 games played. Compared to Stockfish 14, this release introduces a more advanced NNUE architecture and various search improvements. In self play testing, using a book of balanced openings, Stockfish 14.1 wins three times more game pairs than it loses [2]. At this high level, draws are very common, so the Elo difference to Stockfish 14 is about 17 Elo. The NNUE evaluation method, introduced to top level chess with Stockfish 12 about one year ago [3], has now been adopted by several other strong CPU based chess engines. The Stockfish project builds on a thriving community of enthusiasts (thanks everybody!) that contribute their expertise, time, and resources to build a free and open-source chess engine that is robust, widely available, and very strong. We invite our chess fans to join the fishtest testing framework and programmers to contribute to the project [4]. Stay safe and enjoy chess!
