Top Chess Engine Championship
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. 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. 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. The tournament has attracted nearly all the top engines compared to the World Computer Chess Championship.
After 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.
Since season 5, TCEC has been sponsored by Chessdom Arena.
