In contract bridge and similar games, a finesse is a 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.
A Non-simultaneous double squeeze, in the card game of bridge, is a double squeeze in which the pressure is not applied to both opponents at the same trick. Before categorizing a little more about it we will show a diagram for the four basic matrices.
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 squeezee an entry into one or into the other hand is created. For that very reason an entry-shifting squeeze is always a positional squeeze.
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.
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 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.
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.
Loser on loser play is a type of declarer's play in contract bridge, usually in trump contracts, where the declarer discards a loser card on an opponent's winner, instead of ruffing.
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.
