Stockfish is the winner of the Top Chess Engine Championship (TCEC) Season 11. The open source chess engine by Marco Costalba, Joona Kiiski, Gary Linscott and a huge community of contributors, defeated last year’s champion Houdini and crowned itself the new Grand Chess Champion of the competition.
This is the third title for Stockfish, after the victories in Season 6 and Season 9. However, this time Stockfish created history by winning the title in a one of a kind landslide victory. After 85 games Stockfish had the necessary 50,5 points (18 victories, 65 draws, and only two losses), with 15 games to spare the title was in the hands of the open source engine.
The champion version of Stockfish showed significant improvement compared to its predecessor of last season, where it could not make it past the the third position. This year Stockfish qualified from the Premier Division with honors – 7 points ahead of Houdini, and 9,5 points ahead of Komodo. In the Chess Superfinal Stockfish showed muscles right from the start. In the first quarter of the match it already pulled ahead by 5 points, a margin that fans are used to seeing over 100 games or more was now gained much faster.
The final proof of the superiority of Stockfish came around the middle of the match. It then won a game with different colors and the same opening
Like this, by game 50 – the middle of the match – Stockfish had a 12 point advantage (+13 – 1 = 36). The question remaining was not whether it will win the match, but with what margin.
