Compound squeeze

Last updated

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 (so as not to provide immediate winners). 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.

South plays in 6, East having doubled the bid of 5. West leads the 10. Despite the potential defensive ruff, the declarer must duck the lead to East's queen in order to rectify the count. East returns a trump (a red card would reduce the situation to other sorts of squeeze ending). The declarer has 7 spade tricks, a heart, a club, and two diamonds. The twelfth trick can be obtained by compound squeeze: assuming only East guards clubs, he will have to ultimately unguard one of red suits on the first squeeze card; that suit will serve as the "common suit" for the latter double squeeze. The declarer draws trumps, cashing the A in the process for a Vienna coup. When declarer leads the sixth trump (5), the position as on the right diagram is reached.

West discards a heart, dummy a club, but East now has a problem, as he must discard one of red suits:

The motive is similar to the one in guard squeeze East is squeezed in three suits and forced to abandon the help to his partner in one of them.

Contract bridge, or simply bridge, is a trick-taking card game using a standard 52-card deck. In its basic format, it is played by four players in two competing partnerships, with partners sitting opposite each other around a table. Millions of people play bridge worldwide in clubs, tournaments, online and with friends at home, making it one of the world's most popular card games, particularly among seniors. The World Bridge Federation (WBF) is the governing body for international competitive bridge, with numerous other bodies governing it at the regional level.

The double squeeze is a type of squeeze play in the card game of bridge.

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.

Safety play in contract bridge is a generic name for plays in which declarer maximizes the chances for fulfilling the contract by ignoring a chance for a higher score. Declarer uses safety plays to cope with potentially unfavorable layouts of the opponent's cards. In so doing, declarer attempts to ensure the contract even in worst-case scenarios, by giving up the possibility of overtricks.

The stepping-stone squeeze is an advanced type of squeeze in contract bridge. It is used when the declarer has enough high cards to take all but one of the remaining tricks, but does not have enough communication between the hands to cash them. It was analyzed and named by Terence Reese in the book "The Expert Game", also titled "Master Play in Contract Bridge".

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

Polish Club is a bridge bidding system which was developed in Poland, where it is the most popular bidding system, and which is also used by players of other countries. It is a type of small club system.

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.

The Jacoby transfer, or simply transfers, in the card game contract bridge, is a convention in most bridge bidding systems initiated by responder following partner's notrump opening bid that forces opener to rebid in the suit ranked just above that bid by responder. For example, a response in diamonds forces a rebid in hearts and a response in hearts forces a rebid in spades. Transfers are used to show a long suit, usually a major, and to ensure that opener declare the hand if the final contract is in the suit transferred to, preventing the opponents from seeing the cards of the stronger hand.

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.

Morton's fork is a coup in contract bridge that forces an opponent to choose between

  1. letting declarer establish extra tricks in the suit led; or
  2. losing the opportunity to win any trick in the suit led.

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.

Backwash squeeze is a rare squeeze which involves squeezing an opponent which lies behind declarer's menace. A variation of this, known as the "Sydney Squeeze" or "Seres Squeeze", was discovered in play at a rubber bridge game in Sydney, Australia, in 1965, by the Australian great Tim Seres; it was later attested by famous bridge theorist Géza Ottlik in an article in The Bridge World in 1974, as well as in his famous book Adventures in Card Play, co-authored with Hugh Kelsey.

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.
