Anand won the FIDE World Chess Championship in 2000, at a time when the world title was split. He became the undisputed World Champion in 2007 and defended his title against Vladimir Kramnik in 2008. With this win, he became the first player in chess history to have won the World Championship in three different formats: Knockout, Tournament, and Match. He will next defend his title in the World Chess Championship 2009 against Veselin Topalov, the winner of a challenger match against Gata Kamsky in February 2009.
Anand is one of four players in history to break the 2800 mark on the FIDE rating list. He was at the top of the world rankings five out of six times, from April 2007 to July 2008. In October 2008, he dropped out of the world top three ranking for the first time since July 1996.
