For posting: - invitations to games (you can also use the New Game menu or go straight to the Chess Invitation) - information about upcoming tournaments - discussion of games (please limit this to completed games or discussion on how a game has arrived at a certain position ... speculation on who has an advantage or the benefits of potential moves is not permitted) - links to interesting related sites (non-promotional)
Just an idea for another variant - this is where a player can refuse the opponent's move, and make them play an alternative move.
However, once a refusal has been made, the alternative must be accepted. A player may (or may not) refuse once each move.
