Compressione del battitore

Smazzata  510

Winkle  Squeeze

Deal  510

Un esempio di questo tipo di compressione che fu chiamata in questo modo dal grande Terence Reese può essere tratto da una smazzata storica che fu disputata ai trial a coppie americani del 1964 da quattro mostri sacri dell'epoca:

Sud

(Becker)

Ovest

(Stayman)

Nord

(Hayden)

Est

(Mitchell)

La manovra prende di mira la lunghezza di un colore di un lato e gli onori di un altro colore da entrambi i lati.

Il fraintendimento occorso in licita tra NS è evidente, ma la fortuna volle che Stayman decise di attaccare con una piccola quadri secondo gli insegnamenti di Albarran.

L'idea è quello di liberare una presa nel colore di attacco, trovando l'altro onore contiguo dal compagno in modo di battere lo slam incassando l'Asso posseduto

A questo punto, come  avreste cercato di mantenere il vostro impossibile slam?

Becker, senza colpo ferire, fece il sorpasso a quadri, scartò una cuori della mano sull'Asso di quadri e tagliò un terzo giro del colore, poi risalì al morto con l'Asso di fiori per giocare un quarto giro di quadri!

Solo dopo aver affrancato la Dama di quadri, Jay eliminò gli atout avversari portandosi in questo finale di partita a 6 carte, nel quale tirò la Dama di quadri franca e non ce ne fu più per nessuno:

Se Est avesse scartato una picche, Jay si sarebbe liberato di una seconda cuori e avrebbe incassato quattro giri di picche pagando solo l'ultima presa.

Se Est avesse scartato un onore di cuori, Jay si sarebbe ugualmente liberato di una cuori e dopo aver incassato la Dama e l'Asso di picche, avrebbe giocato lui il Fante di cuori! realizzando la 12ª presa chiunque avesse vinto la presa!

Infatti, se avesse vinto la presa Ovest, facendo cadere il Re di Est Sud avrebbe guadagnato il Dieci di cuori del morto!! se avesse vinto la presa Est, il tapino sarebbe stato costretto a riuscire a picche sotto forcella!!

Questo era l'intero campo campo:

En passant, dovete sapere che un campione come Becker era ben felice di giocare abitualmente con Dorothy, una delle poche donne accettata ai tavoli da bridge con il massimo rispetto anche dall'altro sesso.

L'unico attacco capace di battere lo slam sarebbe stato quello a cuori e l'unica manche possibile per NS era quella a SA!

Questa spettacolare smazzata di semi fit tratta da www.bridgeguys.com  ha il suo par in +400 per NS, con i suoi 15 atout consente solo 14 prese (10 a fiori per NS e 4 a cuori per EO).

This term designates a secondary squeeze that forces the opponents to choose between a throw-in and an unblock, but which of each costs a trick. The Winkle Squeeze was analyzed and named by Mr. Terrence Reese.

The origin of the designation of winkle squeeze is unknown, but a winkle is a British term for practically any of the various marine gastropods or sea snails, and is short for periwinkle. Both designations can also be employed as verbs. The perhaps colloquial definition of the verb is to pry, extract, or force from a place or position, which is rather the explanation of the desired action of the declarer once initiated.

The situation of the Winkle Squeeze is such that the declarer has sufficient winners for all but one of the remaining tricks, but the declarer is in a position where he can not take all of his tricks because of entry problems.

The following illustrations should clarify this situation happened during the 1964 United States Pair Trials in Miami Beach, Florida, one board contained what was later to be proclaimed as one of the most famous examples of the Winkle Squeeze, and it is presented below. The board was played by Mr. B.J. Becker - South, Dorothy Hayden - North, Mr. Samuel Stayman - West, and Mr. Victor Mitchell - East, in the compass directions illustrated.

The declarer is South and South leads the Ace of Clubs. East is immediately squeezed in two suits, Spades and Diamonds.

In order to protect the King of Spades, East must discard a Diamond. In the case that East discards a low Diamond, then South will throw East in by leading the Queen of Diamonds. East wins and must return a Spade.

If East decides to discard the Ace of Diamonds on the Ace of Clubs, then South plays the Queen of Diamonds giving West the lead, who must then lead a Diamond to the winning Jack of Diamonds in the dummy:

In hindsight, it seems that the contract 3 No Trump would have been the better game. However, this contract would have been difficult to reach in view of no Heart stopper, and a possible 5-card Heart suit in the holdings of either opponent. The final contract of 6 Clubs was also based on a misunderstanding of the partnership agreement that a bid of 4 Clubs would always be the Gerber convention after a Minor suit opening. South therefore assumed that 4 Spades promised a singleton Heart, and bid the Club slam.

It seems that West, on lead, was also misled by the bidding and decided to lead a Diamond. Had West not been misled, West might have led a Heart, winning three Heart tricks, defeating the slam contract by two tricks before South could do anything.

South happily accepted the lead and finessed with the Jack of Diamonds. South then discarded a Heart on the Ace of Diamonds and ruffed a Diamond. South then entered the dummy with the Ace of Clubs, ruffed another Diamond, which felled the King of Diamonds, establishing the Queen of Diamonds as a winning trick. South then cashed the King and Queen of Clubs, eliminating all outstanding trumps.

The lead was then, on the ninth trick, in the dummy and the position was as follows:

South leads the Queen of Diamonds from the dummy and East is squeezed. East must throw the Queen of Hearts. South throws the 9 of Hearts and West discards a Spade.

South then leads the Queen of Spades, followed by the 8 of Spades, which East covers with the 10 of Spades. South covers and leads the Jack of Hearts.

If East wins, then East must lead from his Spade holding. In this play, however, West, Mr. Stayman, decides to win with the Ace of Hearts, and in this particular case, end-plays himself.

West had to surrender two Heart tricks to the dummy.

In a later analysis, it was determined that had the 6 of Hearts, held by North, and the 5 of Hearts, held by West been interchanged, then the slam would not have been successful, despite the most favourable lead of a Diamond.
