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.
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.
In trick-taking games, to ruff means to play a trump card to a trick. According to the rules of most games, a player must have no cards left in the suit led in order to ruff. Since the other players are constrained to follow suit if they can, even a low trump can win a trick. In some games, like Pinochle and Preferans, the player who cannot follow suit is required to ruff. In others, like Bridge and Whist, he may instead discard. Normally, ruffing will win a trick. But it is also possible that a subsequent player will overruff. This is not always a bad thing—see uppercut below.
An endplay, in bridge and similar games, is a tactical play where a defender is put on lead at a strategic moment, and then has to make a play that loses one or more tricks. Most commonly the losing play either constitutes a free finesse, or else it gives declarer a ruff and discard. In a case where declarer has no entries to dummy, the defender may also be endplayed into leading a suit which can be won in that hand.
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.
In contract bridge, the trump squeeze is a variant of the simple squeeze. In a trump squeeze, declarer has a suit that can be established by ruffing, but the defender being squeezed is guarding that suit. However, if he happens to also guard another suit, the squeeze card will force him to unguard one.
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:
- letting declarer establish extra tricks in the suit led; or
- losing the opportunity to win any trick in the suit led.
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.
A winkle is a rare squeeze/endplay in contract bridge in which a trick is offered to the defenders but whichever wins the trick is then endplayed. Often one defender would be forced to offer a finesse or ruff and discard while the other could overtake and thereby promote a trick in that suit for declarer. The winkle squeeze was named and analyzed by Terence Reese in Master Play in Contract Bridge.
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 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.
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.
