From 20 September - 3 October, some of the world's finest players - including Nakamura, Grischuk, Svidler, Topalov and Ivanchuk - will be in action in what promises to be an exciting tournament. The Grand Prix is part of the World Chess Championship cycle so the Grandmasters will have plenty of motivation to produce fighting chess.
Unfortunately, that means there will be no room for Joe Public spectators on this occasion, but obviously there will be an opportunity to follow the games online.
Further details about the Grand Prix participants can be found here.
With the fourth London Chess Classic scheduled for December and the Candidates event on the way in March 2013, London will be the centre of the chess world for a period of seven months.
