"In 2000, the top three players – Kramnik, Anand and Adams – didn't lose to any of the other seven players. In a very interesting loop, Kramnik beat Anand, Anand beat Adams, and Adams beat Kramnik. When the dust cleared Kramnik and Anand had the same score (6.0/9), and Kramnik was the winner since he had beaten Anand."
