Chess Rating Systems
A chess rating system is a system used in chess to estimate the strength of a player, based on their performance versus other players. They are used by organizations such as FIDE, the US Chess Federation (USCF or US Chess), International Correspondence Chess Federation, and the English Chess Federation. Most of the systems are used to recalculate ratings after a tournament or match but some are used to recalculate ratings after individual games. Popular online chess sites such as Chess.com, Lichess, and Internet Chess Club also implement rating systems. In almost all systems, a higher number indicates a stronger player. In general, players' ratings go up if they perform better than expected and down if they perform worse than expected. The magnitude of the change depends on the rating of their opponents. The Elo rating system is currently the most widely used (though it has many variations and improvements). The Elo-like ratings systems have been adopted in many other contexts, s ...

Free Internet Chess Server
The Free Internet Chess Server (FICS) is a volunteer-run online chess platform. When the original Internet Chess Server (ICS) was commercialized and rebranded as the Internet Chess Club (ICC) in 1995, a group of users and developers came together to fork the code and host an alternative committed to free access. A rivalry between ICC and FICS persisted for years. Users download one of several graphical client programs, connect to the server via telnet, and can play chess or variants at a range of time controls. Games played on FICS are stored in a database, which has been used to train chess engines and to support academic studies. Though based in the US, the user base is international. In addition to the games themselves, there are chat rooms, pairing systems, analysis tools, and ratings. A relay system displays high-profile tournament games for users to see. As of 2024, FICS is still operational, though has declined in popularity with the rise of web-based chess sites. Histo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Correspondence chess is chess played by various forms of long-distance correspondence, traditionally through the postal system. Today it is usually played through a correspondence chess server, a public internet chess forum, or email. Less common methods that have been employed include fax, homing pigeon and phone.

The length of a game played by correspondence can vary depending on the method used to transmit moves: a game played via a server or by email might last no more than a few days, weeks, or months; a game played by post between players in different countries might last several years.
