������Ҫ��Jacoby 2NT -- Forcing Major-Suit Raise(��һ)

There are a number of different conventions designed to help you describe
these strong hands. One of the most popular is the Jacoby 2NT, which was
invented by Oswald Jacoby (who also invented Jacoby Transfers). To use this
convention, your partnership agrees that after you open 1H or 1S and your
partner is an unpassed hand, his jump to 2NT shows: 
 
Forcing-to-game strength (12+ points)  
Good trump support (4 or more cards)  
The 2NT response forces you to at least game level. It is not a suggestion
to play in notrump; it shows support and asks the 1H or 1S opener to further
describe his hand. 
 
Note that the Jacoby 2NT convention is "on" only if responder has not
previously passed in the auction. If you are a passed hand, your jump to 2NT
is natural, showing a balanced hand of 11-12 points.
