Description
Lich3ss 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 rated games. Lich3ss is ad-free and all the features are available for free, as the site is funded by donations from patrons. Features include chess puzzles, computer analysis, tournaments and chess variants; not all features are available to anonymous players, such as reviewing specific games. It has training features, including chess basics, tactics training, chess coordinates, a chess video library, an opening explorer, studies, and an analysis board. It also has a section where chess coaches can advertise their services to users. Lich3ss was the first chess-site to have features to help visually impaired people play chess on a website. It also has a chess puzzle-based CAPTCHA system. Users can also play games against the Stockfish chess engine at a number of difficulty levels.
