Suicide squeeze

Suicide squeeze or cannibal squeeze is a type of squeeze in bridge or whist, in which an opponent is squeezed by a card played by his partner. Normally, this occurs with less-than-perfect defense, but there are also legitimate positions where the defense could not have prevailed.

The most common position for a legitimate suicide squeeze occurs when a side suit is "tangled" (neither side can lead it without giving up a trick), and another suit is protected by the partner of the player who is a trick, as in the following diagram:

 

		♠	-
		♥	-
		♦	Q62
		♣	-
♠	-	N W         E S		♠	-
♥	8			♥	-
♦	J8			♦	K4
♣	-			♣	7
		♠	-
		♥	-
		♦	A10
		♣	3

West is to lead; if he leads a diamond, it will "untangle" the suit for the declarer. However, when he leads the high heart, he induces a simple squeeze on his partner, who must either discard the high ♣7 or unguard the diamond king. (Dummy has an idle card, and East is to play before the declarer).
