The World Chess Championship 2013 was a match between reigning world champion Viswanathan Anand and challenger Magnus Carlsen, to determine the 2013 World Chess Champion. It was held from 9 to 22 November 2013 in Chennai, India, under the auspices of FIDE (the World Chess Federation).
Carlsen won the match 6½–3½ after ten of the twelve scheduled games, becoming the new world chess champion. This was heralded by Garry Kasparov and others as the start of a new era in chess, with Carlsen being the first champion to have developed his game in the age of super-strong chess computers.
The challenger was determined in the 2013 Candidates Tournament. For the first time in more than 50 years it was a double round-robin tournament (instead of a knock-out tournament). It took place in the Institution of Engineering and Technology, Savoy Place, London, from 15 March to 1 April 2013. The participants were:
The tournament had a prize fund of €510,000 ($691,101). Prize money was shared between players tied on points; tiebreaks were not used to allocate it. The prizes for each place were as follows:
Before the tournament Carlsen was considered the favourite, with Kramnik and Aronian being deemed his biggest rivals. Ivanchuk was considered an uncertain variable, due to his instability, and the other players were considered less likely to win the event.
During the first half of the tournament, Aronian and Carlsen were considered the main contestants for first place. At the halfway point they were tied for first, one-and-a-half points ahead of Kramnik and Svidler. In the second half Kramnik, who had drawn his first seven games, became a serious contender after scoring four wins, while Aronian lost three games, and was thus left behind in the race. Carlsen started the second half by staying ahead of the field, but a loss to Ivanchuk allowed Kramnik to take the lead in round 12 by defeating Aronian. In the penultimate round Carlsen pulled level with Kramnik by defeating Radjabov, while Kramnik drew against Gelfand.
