Chess Live, formerly called US Chess Live (when it was affiliated with the United States Chess Federation), was a subscription Internet chess server that opened on August 8, 2000 and closed on 29 May 2007 when it was bought by Internet Chess Club and merged with World Chess Network to form World Chess Live.
There were three membership options: Trial, Basic, and Royal; Basic and Royal levels required periodic payments. Higher levels of membership included more features, such as the ability to observe or participate in certain tournaments often held on the server.
In addition to providing Internet users the opportunity to engage in games of chess with others, Chess Live also provided free lectures on skill and tactics to improve one's ability at the game.
There were a range of paid and voluntary staff positions to ensure the smooth and effective running of the system.
Registered users used a client to connect to the server. At the end there were two versions of the client available: version 4.2.00, an installed program; and version 2.5.1, implemented in Java and that could be run from virtually any Internet-connected computer with a Java-enabled Web browser. Royal members could use non-Chess Live interfaces to connect to the server, such as Thief 1.1, Winboard, or countless other interfaces.
Cheating detection measures
The software had arrangements to try to detect players using the assistance of chess programs. It did this, in part, by detecting task switching activities, based on information being undertaken on the computer that the program was able to detect.
