During the recent Karpov-Kasparov world chess championships they came to an adjournment and left for their hotel. In the lobby of the hotel several chess enthusiasts could be heard bragging, "I could beat Karpov with no problem".
"Oh yeah, I could beat both of them at the same time."
"That's nothing, I could beat both of them blindfolded!"
Finally, the hotel manager had had enough and threw them all out of the hotel.
But why?" a bystander asked.
"Because," the manager replied "I hate ..."chess nuts boasting by an open foyer!"
