It is possible that Mr. Ilyumzhinov is hoping that by offering more money he will get the center’s owners to sell. Or, it may just be a publicity stunt to insert himself into the international debate and thereby raise his profile. He is involved in a bitter campaign for re-election to FIDE against Anatoly Karpov, the former world champion.
If this is really the reason behind the plans, expect a fall out of negotiation to acquire the land anytime soon. But mission accomplished for Ilyumzhinov just the same. Ilyumzhinov has already voiced out his intention to the public that he is dead serious of bringing chess into wide audience, with or without a chess center in New York.
