Knockout squeeze

In bridge, a knockout squeeze is a squeeze in three suits, one of which is the trump suit.^[1] The defender's trump holding is needed to prevent declarer from making a successful play involving trumps, including one as prosaic as ruffing a loser. Because the knockout squeeze does not threaten to promote declarer's trumps to winners (they are often already of winning rank) it is termed a non-material squeeze. Other non-material squeezes include entry squeezes, single-suit squeezes and winkles.
