Cannibal squeeze

Cannibal squeeze or suicide squeeze is a type of squeeze in bridge or whist, in which a defender 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.

Examples

		♠	-
		♥	-
		♦	A Q
		♣	6 2
♠	-	N W               E S		♠	-
♥	8			♥	-
♦	7 3			♦	K 4
♣	4			♣	J 10
West to lead		♠	-
		♥	-
		♦	8 5
		♣	K 3

West is on lead. If he cashes the high heart, a club is thrown from the dummy, and East is squeezed. Whichever card East discards, the declarer will take two tricks in that suit. Instead, West must lead a diamond to protect the partner from subsequent endplay (if he returns a club, the declarer will take the King and put East in with another club, forcing him to lead into ♦AQ).

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 on lead, as in the following diagram:

		♠	-
		♥	-
		♦	Q 6 2
		♣	-
♠	-	N W               E S		♠	-
♥	8			♥	-
♦	J 8			♦	K 4
♣	-			♣	7
West to lead		♠	-
		♥	-
		♦	A 10
		♣	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).
