In 2000, Kramnik played a 16-game match against Garry Kasparov in London, for the Classical Chess World Championship. Kramnik began the match as underdog, but his adoption of the Berlin Defence to Kasparov's Ruy Lopez opening was very effective. With the white pieces, Kramnik pressed Kasparov hard, winning Games 2 and 10 and overlooking winning continuations in Games 4 and 6. Kasparov put up little fight thereafter, agreeing to short draws with the white pieces in Games 9 and 13. Kramnik won the match 8½–6½ without losing a game. This was only the second time in history that a World Champion had lost a match without winning a single game, the other time being Lasker in 1921. It also marked the first time Kasparov had lost a World Championship match.
