The opener's rebid after a fitted 2NT response

PDF
The opener's rebid after a fitted 2NT response.
After an opening 1 of a major, the response 2NT is ultra precise :
  • 4 cards in the major (and not 2, 4 or 5!)
  • 12HCP
  • A balanced hand without a 5-card suitThe 2NT response is a convention, and doesn't guarantee any stoppers. It's non-forcing and the opener can pass.

The opener's rebid
  • With game not sure, the opener can ask his partner if he has something good in his second suit (a sort of trial bid in a suit). He bids that suit.With a balanced hand and the honors sprinkled about, the opener can also propose game in NT. He bids 3NT. The partner either accepts the proposal or else bids 4 hearts or 4 spades.With a strong hand, the opener begins the controls or jumps to 4NT if he holds all the controls!
