Clash squeeze

A clash squeeze is a three suit bridge squeeze with a special kind of menace, referred to as clash menace. The clash menace is one that might fall under a winner in the opposite hand, because it can be covered by another card in an opponent's hand. If the clash squeeze can force the opponent to discard his guard, then the clash menace can be cashed separately from the winner opposite. For example, consider this layout of the spade suit:^[1]

	A 2
K	W N↑ S↓ E	J 10
	Q

The ♠Q is the clash menace. If, when South plays another suit, West can be forced to discard the ♠K, then the ♠Q and the ♠A can be cashed on separate tricks. Notice the presence of the ♠2, a companion that releases the clash menace to be cashed separately from the ♠A. The ♠2 also serves as a simple menace against East, requiring West to retain his clash-menace guard to allow his partner to guard the suit.^[1]^[2]

Clash squeezes were described and analyzed by Chien-Hwa Wang in Bridge Magazine, in 1956 and 1957.
