Features

The website enables anonymous and registered users to play live and correspondence chess games against other players at different cooling off times . There are on the website training functions, including chess basics , tactics training , chess coordinates , video library, player statistics, opening database and studies. Lichess also enables chess players to organize coaching services for themselves.

In addition to blind chess , the website supports the following chess variants :

Lichess has features to help visually impaired people play chess on the site. There is also a chess puzzle based captcha system.

Users can also play games against the Stockfish chess engine at various levels of difficulty. You can also analyze certain positions from standard chess or one of the supported chess variants. The website implements a version of the Stockfish engine that runs on the user's local machine in the user's web browser to allow for limited or infinite analysis that calculates the best game lines or the greatest threats facing the opponent. An opening book based on games played on the site or a database of two million games played by players with a FIDE chess master title is also available. In the Antichess variant, users can switch to the Antichess solution database from Mark Watkins.

Lichess uses a rating system , the Glicko-2-System , for registered players and allows them to take part in tournaments, to write in the forums and to request a server-side full game analysis for every completed game. The ratings for standard chess are categorized into UltraBullet, Bullet, Blitz, Rapid or Classical, depending on the total time of the game or the estimated total time (when using the Fischer time control, which increases the time after each move).

Lichess conducts live tournaments in both standard and variant chess at different time controls, with the slowest time control being 10 minutes per game. Lichess differs from other online chess tournaments in that a member can join and leave the tournament at any time without losing their score if they rejoin during the tournament. The prerequisite for participation in a tournament is that the user has played a sufficient number of games (in the same cooling-off time category or the same variant).
