Lichess
Lichess (/ˈliː.tʃɛs/, LEE-ches) is a free and open-source Internet chess server run by a non-profit organization of the same name. Users of the site can play online chess anonymously and optionally register an account to play games to earn a rating on Lichess. Lichess is ad-free and all the features are available for free, as the site is funded by donations from patrons, who receive a special badge as thanks for their support. Features include chess puzzles, computer analysis, tournaments and chess variants.
Lichess was founded in 2010 by French programmer Thibault Duplessis. The software running Lichess and the design are mostly open source under the AGPL license and other free and non-free licenses. The name Lichess is a "combination of live/light/libre and chess".
On February 11, 2015, an official Lichess mobile app was released for Android devices. An app for mobile devices running iOS was released on March 4, 2015.
In April 2021, the United States Chess Federation announced its official endorsement of Lichess's fair play methodology that automatically detects cheaters based on engine move matching analysis.
As of April 28, 2022, lichess.org had a global rank of 683 at Alexa, with most of its visitors coming from the United States, India, and China. According to its Alexa rank, Lichess is ranked second only to Chess.com as one of the most popular internet chess servers in the world.[needs update]
In December 2017 Lichess began hosting a monthly Lichess Titled Arena with cash prizes for titled players, featuring some of the best players in the world playing bullet chess. Magnus Carlsen won the first titled arena, and has regularly competed and won events since then. Later editions have featured blitz chess as well, and some events were played as Chess 960 events with randomized starting positions for each game.
As of February 2022, Carlsen has a record 17 victories in titled arenas, followed by Alireza Firouzja with 13 victories. Other participants in past editions include Fabiano Caruana, Maxime Vachier-Lagrave, Vladimir Fedoseev, Vladislav Artemiev, Alexander Grischuk, and Anish Giri.
The Saint Louis Chess Club (SLCC) regularly hosted events on Lichess with large prize funds, attracting the world's best players to compete until Lichess terminated the relationship in 2023.
