		<summary type="html">&lt;p&gt;Creazione pagina Jacoby 2NT - convenzione di risposta forcing manche con fit quarto nel nobile&lt;/p&gt;
&lt;p&gt;&lt;b&gt;Nuova pagina&lt;/b&gt;&lt;/p&gt;&lt;div&gt;La &amp;#039;&amp;#039;&amp;#039;Jacoby 2NT&amp;#039;&amp;#039;&amp;#039; (o &amp;#039;&amp;#039;&amp;#039;Jacoby 2SA&amp;#039;&amp;#039;&amp;#039;) è una convenzione di bridge inventata da [[Oswald Jacoby]] negli anni &amp;#039;50. Si tratta di una risposta di 2{{SA}} all&amp;#039;apertura di 1{{cu}} o 1{{pi}} che mostra un fit quarto o più lungo nel colore di atout dell&amp;#039;apertore e valori da manche, forzando almeno a manche nel nobile concordato.&lt;br /&gt;
&lt;br /&gt;
== Storia ==&lt;br /&gt;
&lt;br /&gt;
La convenzione fu sviluppata da [[Oswald Jacoby]], uno dei più grandi campioni e teorici del bridge del XX secolo. Alcuni attribuiscono la paternità della convenzione anche a Leo Baron. La Jacoby 2NT è diventata una delle convenzioni più utilizzate nel bridge moderno, particolarmente nei sistemi Standard American e nei sistemi italiani a 5 nobile.&lt;br /&gt;
&lt;br /&gt;
== Quando si applica ==&lt;br /&gt;
&lt;br /&gt;
La Jacoby 2NT si applica quando:&lt;br /&gt;
* Il partner apre 1{{cu}} o 1{{pi}}&lt;br /&gt;
* Il rispondente non ha precedentemente passato&lt;br /&gt;
* Non ci sono state interferenze avversarie (nella versione classica)&lt;br /&gt;
&lt;br /&gt;
Se il rispondente è un passato di mano, la risposta di 2{{SA}} è naturale (11-12 punti bilanciati) e non convenzionale.&lt;br /&gt;
&lt;br /&gt;
== Requisiti per la risposta 2{{SA}} ==&lt;br /&gt;
&lt;br /&gt;
Nella &amp;#039;&amp;#039;&amp;#039;versione classica&amp;#039;&amp;#039;&amp;#039; (Standard American e maggioranza dei sistemi), la Jacoby 2NT richiede:&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Fit quarto o più lungo&amp;#039;&amp;#039;&amp;#039; (4+ carte) nel nobile dell&amp;#039;apertore&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;13+ punti onori&amp;#039;&amp;#039;&amp;#039; (valori da manche)&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Forcing a manche&amp;#039;&amp;#039;&amp;#039; nel colore nobile concordato&lt;br /&gt;
&lt;br /&gt;
La convenzione è utilizzata principalmente per esplorare possibilità di slam quando si ha già concordato l&amp;#039;atout e forza sufficiente per la manche.&lt;br /&gt;
&lt;br /&gt;
== Risposte dell&amp;#039;apertore ==&lt;br /&gt;
&lt;br /&gt;
Dopo la risposta di 2{{SA}} Jacoby, l&amp;#039;apertore descrive la propria mano secondo il seguente schema standard:&lt;br /&gt;
&lt;br /&gt;
=== Con distribuzione corta (singleton o chicane) ===&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;3{{fi}}/3{{qu}}/3{{cu}}/3{{pi}}&amp;#039;&amp;#039;&amp;#039;: Mostra un singleton o chicane nel colore dichiarato (il colore corto). Questa è l&amp;#039;informazione più importante per valutare lo slam, in quanto i controlli nei colori corti sono fondamentali.&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;4{{fi}}/4{{qu}}/4{{cu}}&amp;#039;&amp;#039;&amp;#039;: Nelle varianti moderne, un salto a livello 4 può mostrare una chicane (vuoto) anziché un singleton, oppure una buona quinta laterale.&lt;br /&gt;
&lt;br /&gt;
=== Senza distribuzione corta ===&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;3{{SA}}&amp;#039;&amp;#039;&amp;#039;: Mano media (15-17 punti), bilanciata o semi-bilanciata, senza singoli né chicane&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;3 del nobile d&amp;#039;apertura&amp;#039;&amp;#039;&amp;#039; (3{{cu}} dopo 1{{cu}}, o 3{{pi}} dopo 1{{pi}}): Mano con interesse per lo slam, tipicamente 15+ punti con sesta del nobile o valori concentrati, nega distribuzione corta&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;4 del nobile d&amp;#039;apertura&amp;#039;&amp;#039;&amp;#039; (4{{cu}} dopo 1{{cu}}, o 4{{pi}} dopo 1{{pi}}): Mano minima (12-14 punti), chiusura a manche senza interesse per lo slam&lt;br /&gt;
&lt;br /&gt;
== Sviluppi successivi ==&lt;br /&gt;
&lt;br /&gt;
Dopo la risposta dell&amp;#039;apertore alla Jacoby 2NT, la coppia procede secondo questi criteri:&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Controlli e cue-bid&amp;#039;&amp;#039;&amp;#039;: Se c&amp;#039;è interesse per lo slam, si iniziano a dichiarare i controlli (Assi e Re) nei vari colori&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;[[Blackwood]]&amp;#039;&amp;#039;&amp;#039; o &amp;#039;&amp;#039;&amp;#039;[[RKCB]]&amp;#039;&amp;#039;&amp;#039;: Si può richiedere il numero di Assi (o chiavi) per verificare la possibilità di slam&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Chiusura a manche&amp;#039;&amp;#039;&amp;#039;: Se non c&amp;#039;è interesse per lo slam, si chiude a 4 del nobile concordato&lt;br /&gt;
&lt;br /&gt;

&amp;#039;&amp;#039;&amp;#039;Spiegazione&amp;#039;&amp;#039;&amp;#039;: Ovest apre 1{{pi}}, Est risponde 2{{SA}} Jacoby. Ovest con mano minima (13 punti) e distribuzione 5-3-3-2 chiude direttamente a 4{{pi}}, negando interesse per lo slam.&lt;br /&gt;
&lt;br /&gt;

&amp;#039;&amp;#039;&amp;#039;Spiegazione&amp;#039;&amp;#039;&amp;#039;: Ovest apre 1{{pi}}, Est risponde 2{{SA}} Jacoby. Ovest con 16 punti e distribuzione 5-3-3-2 dichiara 3{{SA}} (mano media senza singleton). Est senza interesse per lo slam chiude a 4{{pi}}.&lt;br /&gt;
&lt;br /&gt;
== Varianti ==&lt;br /&gt;
&lt;br /&gt;
=== Jacoby 2NT classica (13+ punti) ===&lt;br /&gt;
&lt;br /&gt;
La versione standard richiede 13+ punti e forcing manche. È la versione più diffusa nei sistemi Standard American e nei tornei internazionali.&lt;br /&gt;
&lt;br /&gt;
=== Jacoby 2NT modificata ===&lt;br /&gt;
&lt;br /&gt;
Alcune coppie utilizzano varianti modificate, come:&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Jacoby 2NT con interferenza&amp;#039;&amp;#039;&amp;#039;: Alcune coppie giocano la Jacoby anche dopo interferenza avversaria&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Risposte invertite&amp;#039;&amp;#039;&amp;#039;: Alcune coppie invertono il significato di 3{{SA}} e 3 del nobile per distinguere meglio forza e distribuzione&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Salti a livello 4&amp;#039;&amp;#039;&amp;#039;: Alcuni accordi usano i salti 4{{fi}}/4{{qu}}/4{{cu}} per mostrare chicane anziché quinte laterali&lt;br /&gt;
&lt;br /&gt;
=== Variante italiana invitante ===&lt;br /&gt;
&lt;br /&gt;
In alcuni sistemi italiani esiste una variante &amp;quot;invitante&amp;quot; della Jacoby 2NT con 9-12 punti, mentre il salto diretto a manche (1{{pi}}-4{{pi}} o 1{{cu}}-4{{cu}}) può avere significati diversi. Tuttavia questa variante non è universalmente adottata e richiede accordi specifici tra i partner.&lt;br /&gt;
&lt;br /&gt;
== Vantaggi ==&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Esplorazione slam efficiente&amp;#039;&amp;#039;&amp;#039;: Permette di esplorare lo slam quando si ha già fit nel nobile, lasciando spazio per scambiare informazioni&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Mostra distribuzione corta&amp;#039;&amp;#039;&amp;#039;: La possibilità di mostrare singleton e chicane è fondamentale per valutare le prese complementari&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Distingue forza dell&amp;#039;apertore&amp;#039;&amp;#039;&amp;#039;: Le diverse risposte permettono all&amp;#039;apertore di distinguere mano minima, media o massima&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Forcing manche&amp;#039;&amp;#039;&amp;#039;: Evita il rischio di fermarsi sotto manche quando ci sono i valori&lt;br /&gt;
&lt;br /&gt;
== Svantaggi ==&lt;br /&gt;
&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Occupa spazio licitative&amp;#039;&amp;#039;&amp;#039;: La risposta di 2{{SA}} toglie spazio ad altre chiamate naturali&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Richiede accordi precisi&amp;#039;&amp;#039;&amp;#039;: Le risposte dell&amp;#039;apertore devono essere concordate con precisione nella coppia&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Vulnerabile alle interferenze&amp;#039;&amp;#039;&amp;#039;: Gli avversari possono interferire dopo 2{{SA}} rendendo difficile lo scambio di informazioni&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Non utilizzabile da passato di mano&amp;#039;&amp;#039;&amp;#039;: Se il rispondente ha già passato, 2{{SA}} diventa naturale&lt;br /&gt;
