The concept involves a secondary squeeze that leads to a suit establishment play. Although the name of the squeeze has been anglicized, the English spelling would be v-i-s-e.
Note: The word vise or vice is, among other definitions, a device, tool, or appliance for holding stationary an object while external forces are being applied.
West QJ K
South 3 Q A
The declarer is South, who leads the Ace of Clubs. West, as can readily be seen, is squeezed in both suits. In the case that West discards the King of Hearts, the Queen of Hearts, held by South, becomes a winner. In the case that West discards a Spade, then South can establish one more trick in Spades, since East will be forced to return a Spade.
This particular position appears to be similar to an automatic squeeze against West, but the position has been modified in a particular manner. Instead of a two-card menace, the situation presents a vice (vise) menace consisting of the second-best card of the suit accompanied by a card which can be established if West weakens his second-round stopper.
North K10 AJ
West QJ KQ
East A84 5
South 75 7 A
South is the declarer and leads the Ace of Diamonds. This play forces West to unguard Hearts, giving South two winners in Hearts. West can also discard his second-round trick in Spades, giving South a second trick in Spades.
This particular position is a modification of the simple positional squeeze. The vice (vise) menace does not provide an entry, so the threat by North must be accompanied by a master card in the suit, which makes it a two-card threat. Equally, East must have no trick to cash besides his stopper in the doubly-guarded suit.
