| Correspondence chess ?
Correspondence chess is chess played by some sort of long-distance correspondence,
usually through a Correspondence Chess Server. A correspondence chess server like Chess-Mail keeps track of games, validate moves,
and notify players of submitted moves by e-mail.
Correspondence chess allows people geographically distant to play one another without meeting in person.
The length of a game played by correspondence chess can vary depending on the method used to transmit the moves -
a game played on the internet via online chess server may last from several weeks to several months.
In correspondence chess several games are usually played at once.
