1NT Opening
15–17 HCP
- Stayman 2♣
Opener’s 2♥ does not deny four spades. Responder’s subsequent bidding is natural: forcing at the 3-level, non-forcing at the 2-level. Also: 1NT - 2♣; 2♦ - 2♠ = invitational (7–9 HCP), 5 spades, 4 hearts, and 1NT - 2♣; 2♥/2♠ - 3♦/3♥ = transfer, agrees Opener’s suit, GF
- Jacoby transfers 2♦/2♥
Transfer to hearts (2♦) does not deny five spades. Responder’s new suit at the 3-level forces to game. Also: 1NT - 2♦; 2♥ - 2♠ forces to 3♥ (8+ HCP)
- 2♠ response – transfer for clubs. Opener may choose between a positive 2NT, and a negative 3♣. Responder may continue by showing shortage.
- 2NT response – limit
- 3♣ response – transfer to diamonds, weak or strong Opener is obliged to bid 3♦. Responder may continue by showing shortage.
- 3♦ – natural, inviting
- 3♥/3♠ – 5431 convention: GF, both minors: at least 5-4, shortage in the bid suit

Famous quotes containing the word opening:
“The opening of large tracts by the ice-cutters commonly causes a pond to break up earlier; for the water, agitated by the wind, even in cold weather, wears away the surrounding ice.”
—Henry David Thoreau (1817–1862)
