It was billed as one of the great chess rivalries of all-time, and this week there's a nostalgic rematch as old foes Kasparov and Karpov play a 12 game (4 Rapid and 8 blitz) match in Valencia 22nd-24th September, 2009.
The match is held to commemorate the 25th Anniversary of the start of their infamous first aborted title match in Moscow in 1984-5; this was followed by an epic series of close World title matches that concluded in Lyon, France, 1990.
