Bobby Fischer and Boris Spassky were playing a championship chess tournament in Reykjavik. The auditorium became very hot, which bothered both players, so they agreed to move the game into the foyer, where it was cooler.
Immediately, both players started telling each other, the kibbitzers and the spectators of some of the great gambits they had invented.
Someone walked in on the game, and asked what was going on.
“Oh,they’re just chess nuts boasting in an open foyer.”
