More examples of your second bid after partner bids Jacoby 2NT

Today we look at more examples of your second bid after partner responds with the convention Jacoby 2NT to your One Heart or One Spade opening. Your decision always depends on the strength and distribution of your hand. After Jacoby 2NT, your partnership must not stop bidding short of game.

Case 1:

Spades AKQJx
Hearts Q
Diamonds Axxx
Clubs Kxx

Case 1: With 20 points including one length point in this unbalanced hand, you open One Spade. After partner bids the convention Jacoby 2NT, you bid Three Diamonds showing the Ace or void in Diamonds. If partner bids Three Hearts showing the Ace or void in Hearts, you now show your great hand. You bid Three Spades to suggest partner consider slam. You bid Four Spades to suggest game only. Partner makes the final decision.

Case 2:

Spades x
Hearts Axx
Diamonds AQxxx
Clubs AKxx

Case 2: This is a trick question! You open One Diamond with your 18 points including one length point. Partner responds 2NT. You bid 3NT. This is a trick question because the 2NT is a limit raise (10-12 points) after a minor suit opening. The convention Jacoby 2NT partner response applies only to your opening of One Heart or One Spade.

Case 3:

Spades Void
Hearts AQxxx
Diamonds Kxx
Clubs AQxxx

Case 3: With 17 points including two length points, you open this hand One Heart. Partner responds Jacoby 2NT. You then bid Three Spades (up the line) to show your void in Spades. If partner encourages, you next show your Ace of Clubs by bidding Five Clubs. Otherwise you just bid Four Hearts to show partner you are happy with just the game score.
