During the 2008 Corus chess tournament, Cheparinov's game in the eighth round of Group B against Nigel Short was declared a forfeit after the first move because he had twice refused to shake Short's hand at the start. After Cheparinov refused to shake hands, Short informed the arbiter that in such cases, the rules prescribe an immediate forfeit (Short claims that the arbiter was not aware of this rule and had to be reminded of it). Cheparinov's team claimed the arbiter was not aware of the rule since there is no such rule. The Topalov–Kramnik game at the same tournament started without a handshake, although in that case neither player 'refused' a handshake since neither had offered one. FIDE's behavioural norms state that, player who does not shake hands with the opponent [... before the game starts in a FIDE tournament or during a FIDE match (and does not do it after being asked to do so by the arbiter) [...] will immediately and finally lose the relevant game.
