An initial rating is given to any new participant based on its rating in other chess engine rating lists.Ĭriteria for entering the competition TCEC generates an Elo rating list from the matches played during the tournament. In previous seasons, if an engine crashes 3 times in one event, it is disqualified to avoid distorting the results for the other engines however starting in TCEC Season 20, an engine is allowed to crash as many times as possible without being disqualified from the current event however, the engine will still be disqualified from future events unless the crash is fixed. Engines are allowed updates between stages if there is a critical play-limiting bug, they are also allowed to be updated once during the stage. Large pages are disabled, but access to various endgame tablebases is permitted. All engines run on mostly the same hardware and use the same opening book, which is set by the organizers and changed in every stage. Starting in season 13, there was also a cup tournament consisting of the top 32 engines in the main tournament, resulting in a 5-round single elimination tournament. Prior to season 11, the tournament used a cup format, while starting in Season 11, the tournament used a division system. This tournament consisted of several qualifying stages and one 'superfinal', and the winner of the superfinal is called the 'TCEC Grand Champion' until the next season.

Prior to season 21, there was originally one tournament in each season.

Additionally, seasons contain various bonus contests, like the 'Viewer Submitted Opening Bonus'. Each season is divided into several tournaments: a Leagues Season, a Cup, a Swiss tournament, a Fischer Random Chess tournament. The TCEC competition is divided into seasons, where each season happens over a course of a few months, with matches played round-the-clock and broadcast live over the internet. Since season 5, TCEC has been sponsored by Chessdom Arena.

The tournament has attracted nearly all the top engines compared to the World Computer Chess Championship.Īfter a short break in 2012, TCEC was restarted in early 2013 (as nTCEC) and is currently active (renamed as TCEC in early 2014) with 24/7 live broadcasts of chess matches on its website. It is often regarded as the Unofficial World Computer Chess Championship because of its strong participant line-up and long time-control matches on high-end hardware, giving rise to very high-class chess. It was organized, directed, and hosted by Martin Thoresen until the end of Season 6 from Season 7 onward it has been organized by Chessdom. Top Chess Engine Championship, formerly known as Thoresen Chess Engines Competition ( TCEC or nTCEC), is a computer chess tournament that has been run since 2010.
