Double-Barreled Stayman

Double-Barreled Stayman is a variation of the Stayman convention. A 2 response to 1NT is game-forcing Stayman, showing at least one 4-card major. Using this approach, the 2 response to 1NT is made with weak or invitational hands.

2 shows game-forcing values (minimum strength determined by the opening 1NT range). It asks partner to bid his cheapest 4-card major, if he has one.

Opener's Rebids

Opener's first priority is to show a 4-card major. Lacking one, he should bid 2NT or a minor suit.

2 Shows 4 hearts.
2 Shows 4 spades and denies as many as 4 hearts.
2NT Denies a 4-card major or 5-card minor. Opener's shape is 4432 or 4333.
3 Shows a 5-card club suit, and denies a 4-card major.
3 Shows a 5-card diamond suit, and denies a 4-card major.

Other Considerations

The major drawback of Two-Way Stayman is that you lose the ability to play 2 as a Jacoby Transfer to hearts.
