text: 2006 Reunification match When Garry Kasparov broke with FIDE, the federation governing professional chess, to play the 1993 World Championship with Nigel Short, he created a rift in the chess world. In response, FIDE sanctioned a match between Anatoly Karpov and Jan Timman for the FIDE World Championship, which Karpov won. Subsequently, the chess world had seen two "champions": the "classical" championship, claiming lineage dating back to Steinitz; and the FIDE-endorsed champion.
  When Kramnik defeated Kasparov and inherited Kasparov's title, he also inherited some controversies. At FIDE World Chess Championship 2005, Kramnik refused to participate, but indicated his willingness to play a match against the winner to unify the world championship. After the tournament, negotiations began for a reunification match between Kramnik and the new FIDE World Champion—Veselin Topalov of Bulgaria.
  In April 2006, FIDE announced a reunification match between Kramnik and Topalov—the FIDE World Chess Championship 2006. The match took place in Elista, Kalmykia. After the first four games, Kramnik led 3–1 (out of a maximum of 12). After the fourth game, however, Topalov's coach/manager Silvio Danailov protested that Kramnik was using the toilet suspiciously frequently, implying that he was somehow receiving outside assistance whilst doing so. Topalov said that he would refuse to shake hands with Kramnik in the remaining games. The Appeals committee decided that the players' toilets be locked and that they be forced to use a shared toilet, accompanied by an assistant arbiter.
