Lichess Official Blog
Lichess (
/'liː-tʃɛs/ (help·info)[5]) is a free, non-profit Internet chess server. Its primary aim is to enable a free, "world-class" chess experience for anyone, anywhere. It does not require registration; anyone can play anonymously. All features are available for free, with the exception that one may earn an honorary badge of patron status through regular donations.[6][7][8]MY COMMET: Only about 1% of lichess.org chess players are patrons but everyone is equal. The numerous excellent features are available to everyone for free (no ads, no begging for money, people have to go out of their way to find out how to be a patron).
Features[edit]
The website allows users to play games of live and correspondence chess against other players at different time controls. It has training features, including chess basics, tactics training, chess coordinates and studies. It also enables avid chess players to arrange coaching services for themselves.

- Horde (a variant of Dunsany's chess)
- King of the Hill

Lichess has features to assist visually impaired people to play chess on the website.[12] It also has a chess puzzle-based CAPTCHA system.[13]
Lichess enables streaming via twitch.tv, hitbox.tv, and YouTube, and features many established players such as Grandmaster Eric Hansen, International Master Greg Shahade, International Master John Bartholomew, National Master ChessNetwork and many other online chess celebrities.
Users can also play games against the Stockfish chess engine at a number of difficulty levels. They may also analyze specific positions from standard chess or any of the supported chess variants, with the help of the following features:
- Run Stockfish engine on local machine within the user's web browser for limited or infinite analysis,[14] which will calculate best lines of play or major opponent threats.
- Promptly receive in-depth analysis from other users, which has been previously stored in Lichess cloud system.[15]
- Consult opening books,[16] based on the entire game database from Lichess. In standard chess, users can switch to a Master's database created from 2 million FIDE games from titled masters and grandmasters. In AntiChess variant, users can switch for Mark Watkins's anti-chess solution database.[17]
- Check Syzygy Endgame Tablebases for a perfect play when there are just 6 or less pieces on the board.
For registered players Lichess employs a rating system, and grants the ability to compete in tournaments, post in the forums, and request a server-side full game analysis for any finalized game. The ratings for standard chess are categorized into Ultrabullet, Bullet, Blitz or Classical, depending on the game's estimated total time (see chess time controls).
Based on a 40-move estimate, the game's total time e is calculated from the initial clock time t and the number of seconds i added to the clock after each move, as e = t + 2i3. For example, a 15m + 15s game has the same total time as 25m since 15+(15*2/3) = 25.
Live Tournaments[edit]
lichess runs live tournaments both in standard chess and in variant chess, and at different time controls, with the slowest time control being 10 minutes per game. Where it differs from other online chess tournaments is they are run in an "arena" where a member can join and leave at any time (whilst not actually playing). For users who wish to take a "gamble" there is a "berserk" mode, which handicaps them by removing half their time (so if is played at a 5+0 time control, they only get 2.5 minutes to play all their moves). If they achieve a win (in 7 moves or more) or a draw (in 11 moves or more) they get an extra point. [18]
In order to join a tournament, there is a requirement for the user to have played a sufficient number of games (in the same time control or the same variant).
Policy against cheating and abusive behaviour[edit]
If a player has been caught cheating, usually by use of software assistance, but often by other means to achieve an artificial rating (e.g. deliberating losing games (sandbagging) to lower their rating) their account is marked with a label. They can still use the site but cannot compete in rated games and cannot join tournaments. [19]
Players who are abusive may similarly find they are silenced in the chat and forum facilities so that others cannot read what they type. This is a separate issue to players who cheat. One form of abuse, for example, is open accusations of cheating.
Mobile app[edit]

MY COMMENT: Mr. Duplessis from Paris France is the creator of the fantastic Lichess.org. He is an atheist.

Benevolent dictator of lichess.org, a hippie communist chess server for drug fueled atheists.
