Viktor Korchnoi was scheduled to play a match with Ben Finegold in St. Louis next week, concurrent with the Hikaru Nakamura-Ruslan Ponomariov match, but has had to cancel due to health concerns. According to the organizers, the concerns are not serious in the big picture, but are enough to impair Korchnoi's ability to travel internationally. It's a pity Finegold and for fans who hoped to see the legend in person, and of course for Korchnoi himself. There will still be a Finegold match, however, as Ray Robson has been enlisted to fill in.
