The finish of the 2005 World Chess Championship qualified Anand for the 2007 championship, an eight-player double round-robin tournament held in Mexico City from 12 to 30 September 2007. In 2006, Kramnik took Topalov's place in the event after his victory over the latter to reunify the world title. Anand entered the tournament as the world's top-ranked player, and was considered a favourite to win alongside the defending champion Kramnik.
