It seems a group of chess enthusiasts had completed their tournament for the day and so they all checked into a hotel.  They enjoyed an evening meal and cigars and then went to stand in the lobby to discuss their recent tournament victories.

After about an hour, the hotel manager came out of the office and, in angry voice, asked them to disperse immediately.

But why?", they asked, as they slowly moved off.

"Because....," he said, ..............."I can't stand chess nuts boasting in an open foyer."
