THE FLYING SCOTSMAN TO DENVER

An opening move in chess. It is performed by throwing the heaviest piece on the board (usually the Queen or a Rook) at the back of your opponent's head when they turn around to get drinks. If successful, this move causes an instant checkmate and prevents the playing of any further games against this opponent.
