Non-simultaneous double squeeze

Last updated

In bridge, a non-simultaneous double squeeze is a double squeeze in which the pressure is not applied to both opponents at the same trick. [1] Before categorizing a little more about it we will show a diagram for the four basic matrices.

1) When the club ace is played West is squeezed immediately and has to shed a spade. North plays the now useless jack of hearts and East still has an idle card to throw, the three of hearts. But when the heart deuce is led up to the ace, East is squeezed on his turn in the pointed suits. This is a positional squeeze.

2) When the club ace is played West can shed a heart, but East is squeezed and has to give up his spade guard. When the heart deuce is led to the ace it is West who is squeezed in the pointed suits. This is an automatic squeeze.

3) When the club ace is played West is squeezed immediately and has to shed a spade. North plays the now useless jack of hearts and East still has an idle card to throw, the three of hearts. A spade is led to the king and the heart ace is cashed. On that card East is squeezed in the pointed suits. This is a positional squeeze.

4)When the club ace is played West is squeezed immediately and has to shed a spade. Two hearts are cashed and East is squeezed between the pointed suits on the second of them. This is an automatic squeeze.

In all double squeezes the second squeeze card is opposed to (that is in the other hand than) the first squeeze card (it could be in the same hand in diagram (2) though). The double menace is always in the same hand than the first squeeze card. In matrices (1) and (2) the second squeeze executes immediately after the first. For that reason the squeeze card is an entry to North. In matrices (3) and (4) we cross to the North hand and then execute the squeeze, two tricks later than the first one. But that could even be later as demonstrated by the following diagram, which is a somehow extreme variation of (4).

We have an eight card ending and by playing the club ace West is squeezed, forced to give up a spade. East will be squeezed five tricks later on the heart ten.

In contract bridge and similar games, a finesse is a type of card play technique which will enable a player to win an additional trick or tricks should there be a favorable position of one or more cards in the hands of the opponents.

In contract bridge, a simultaneous double squeeze is a double squeeze in which both opponents are squeezed by the same card, as opposed to non-simultaneous double squeeze where the two opponents are squeezed in different tricks.

The simple squeeze is the most basic form of a squeeze in contract bridge. When declarer plays a winner in one suit, an opponent is forced to discard a stopper in one of declarer's two threat suits.

In the card game contract bridge, an entry-shifting squeeze is a mixture between a material squeeze and an immaterial squeeze. The material part is the same as in a trump squeeze or a squeeze without the count. The immaterial part is that depending on the choice of discards of the squeeze an entry into one or into the other hand is created. For that very reason an entry-shifting squeeze is always a positional squeeze.

The progressive squeeze is a contract bridge squeeze that gains two tricks by squeezing one and the same player twice, hence the name. A progressive squeezes is a subset of triple squeezes that, depending both on entries and on positional factors, may result in a subsequent, simple, two-suit squeeze that takes place against the opponent who has just been triple squeezed. Confusing the issue is that some triple squeezes can become progressive squeezes through misdefense.

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.

In the card game of contract bridge, to hold up means to play low to a trick led by the opponents, losing it intentionally in order to sever their communication. The primary purpose is to give as many tricks to opponents as needed to exhaust all the cards in the suit from one of their hands. If that hand regains the lead, it will not be able to put the partner on lead to cash its tricks. Hold up is one of basic techniques in play.

A strip squeeze is a declarer technique at contract bridge combining elements of squeeze and endplay.

In contract bridge, the trump squeeze is a variant of the simple squeeze in which one threat is a suit that if unguarded can be established by ruffing.

Pseudo-squeeze is a type of deceptive play in contract bridge. The declarer goes through the motions of executing a genuine squeeze where none exists, in the hope that a defender misreads the actual position and misdefends. The pseudo-squeeze simply gives the defender able to recognize the possibility of a squeezed position a chance to go wrong.

A compound squeeze is a type of play in the game of contract bridge. In this squeeze one opponent is squeezed such that some form of other squeeze emerges involving either or both players. Usually this term is used to reference a pentagonal squeeze. In this form of squeeze both players guard two suits, and one player guards a third suit. On the play of a card the player guarding three suits must give up one of the shared guards . Now each opponent singly guards one suit, and there is a third suit that is jointly guarded. This means that a double squeeze matrix exists. Note that there are pseudo compound squeezes, where the triply squeezed opponent can select the 'correct' shared suit, such that the entry situation precludes the proper functioning of the double squeeze.

The trump coup is a contract bridge coup used when the hand on lead has no trumps remaining, while the next hand in rotation has only trumps, including a high one that would have been onside for a direct finesse if a trump could have been led. The play involves forcing that hand to ruff, only to be overruffed. A similar motive is met in coup en passant, where indirect finesse is used instead of direct.

These terms are used in contract bridge, using duplicate or rubber scoring. Some of them are also used in whist, bid whist, the obsolete game auction bridge, and other trick-taking games. This glossary supplements the Glossary of card game terms.

A triple squeeze is a squeeze against one player, in three suits; a more explicit definition is "three simple squeezes against the same player."

A guard squeeze is a type of squeeze in contract bridge where a player is squeezed out of a card which prevents his partner from being finessed. The squeeze operates in three suits, where the squeezed player protects the menaces in two suits, but cannot help his partner anymore in the third suit after the squeeze is executed.

The Bath coup is a coup in the game of contract bridge in which the declarer, who holds AJx(x) in a suit, ducks the left-hand opponent's lead of a king in that suit. The coup is presumed to be named after the city of Bath in England and dates from the game of whist, the predecessor of bridge.

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:

An entry squeeze move in contract bridge exerts pressure by threatening the length of a defender's holding in a side suit. In many familiar squeezed positions, such as a simple or double squeeze, the rank of a defender's holding prevents declarer from cashing a threat until the squeeze has matured. This situation is also present in entry squeezes, but in addition a defensive holding interferes with declarer's entries, preventing declarer from effectively going back and forth between his hand and dummy.

In bridge, a knockout squeeze is a squeeze in three suits, one of which is the trump suit. 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 it is termed a non-material squeeze. Other non-material squeezes include entry squeezes, single-suit squeezes and winkles.

The saturated squeeze is a type of squeeze play in the card game of Bridge.
