You caught a 2 NT call (Jacoby 2NT) from partner, promising a game-forcing raise with at least four spades. As 14 HCP hands go, this one leaves much to be desired. Now what?

ANSWER: Bid 4  showing the secondary five-card suit.

THE PRINCIPLE: When responding to a Jacoby 2 NT major suit raise, the conventional rebids are, in priority order:
  • 4 of a new suit = secondary five-card suit
  • 3 of a new suit = singleton or void in that suit
  • 3 of the major = no shortness, extra values (17+) and slam interest
  • 3 NT = good 13-15, balanced
  • 4 of the major = signoff with no extra values or shortness
If you have a secondary five-card suit, that is the most important characteristic of your hand. Perforce you must also have a singleton or void in another suit. Tell partner about the five-card suit, and she can usually work out the rest.

If you instead rebid 3  to show shortness in hearts here, partner may likely think that her heart values are all wasted and not move beyond game. If you tell her about your five-card club suit, she can easily find the way to the very good 6 ♠ contract.
