Jacoby 2NT Response Bid

The Jacoby 2NT Response Bid is a response bid made after partner has made an opening bid of a 5 card major. The response bidder has at least 13 points and four-card support for the major suit opened by the partner.

The Jacoby 2NT response bid, after partner has opened 1H/1S, requests opener to describe the complexion of openerπs hand containing a 5 card major.

Opener's rebids

If you opened 1 of a major (H/S) and partner responds 2NT:

1) If you have a singleton or a void, bid 3 of that suit.

2) If you have another 5-card suit with honors, bid 4 of that suit.

3) If you have extra values with balanced hand, bid 3NT

4) If you have extra values and extra length in your major, bid 3 of the major

5) If you have a minimum opener with no singleton or void, jump to 4 of your suit.

For example, when you open 1H/1S and your partner responds 2NT, opener`s rebids are as follows:

1) 3C, 3D or 3S/3H = Singleton or void in that suit.

2) 3H/3S = 14 or more points with extra length in your suit or 18 HCP with no singleton.

3) 3NT = 15-18 points with a balanced hand

4) 4C, 4D, 4S/4H = A five-card suit headed by a K or equivalent

5) 4S = Minimum hand (12-14HCP and no singleton)

The decision to bid game or slam is then made by the responder. Responder may sign off at game. If responder wants to explore further, cuebids for Aces, Blackwood, or Gerber are available for slam attempts.
