FICS is accessible via
telnet and was text-only by default. Before graphical interfaces, users would see a board created by
ASCII characters, with the lines of the board created by
hyphens and
pipes, and pieces represented by letters. The traditional FICS interface was a dedicated client built with pre-web technology, but web-based interfaces are also supported. Users can play using an anonymous guest account or register for an account with a username. Registered users can play games rated using the
Glicko rating system, with separate ratings based on time control and chess variant. Once connected, discussion takes place in a wide number of function-specific or subject-specific chat channels numbered 0 through 255. For example, channel 0 is for administrators only, 1 is for general help, 50 is general chat, and 49 is for tournaments. FICS, like ICS, is based in the US, but it has been notable for its international diversity. Early descriptions of using the servers highlight playing against and talking with people from around the world, which was a rare experience in the 1990s.
Relay FICS relays major live chess events. A bot takes the moves in ongoing games and relays them to special demo accounts bearing the names of players in the event. Users watch and comment on the games in progress. The relay has covered several
World Chess Championships as well as
Wijk aan Zee,
Morelia-Linares and
Amber Melody. The web-based
Lichess platform obtains its tournament relays via FICS.
Archive All games played by registered users are recorded and made publicly available for free. The FICS game archive has been used in
chess opening studies, academic studies on memory, decision-making, The server and its archive have been used to train
chess engines and chess-related
machine learning projects, while the FICS code has been used to launch similar regional or thematic chess servers as well as influencing the design of other chess projects. == See also ==
