  1. 1 NT openings Review and intro to competitive bidding

  2. What does 1 NT opening mean • 1 NT opening shows • 15 to 17 high card points • Balanced Hand • No singletons or voids • No 2 doubletons • No need to have stoppers in all suits • E.g.: S AJx, H KQ9x, D KQx, C xx : open 1NT • Prefer to open 1N if hand satisfies above criteria, even if hand fits some other opening bid

  3. Responses • Pass = Weak balanced hand, <7 hcp • 2D/2H/2S = 5+ cards in bid suit, <8 hcp • Sign-off, asking opener to pass • 2N = Good 8 or 9 points, invite to 3N • 3 of a suit = 6 card suit or good 5 card suit • Game force, possible slam try in that suit • 4H/4S = To play, 6+ cards • 2C = Stayman, asks opener to bid 4 card major suit if she has one

  4. Rebids by opener • After 3 of a suit • Bid 3N with no support for responder’s suit • With support, cue-bid a suit where you have a control (A or K) • If unable to cue-bid, raise to 4 of the suit, with some ruffing value • After Stayman • Bid 2M with a 4 card major (with both, start with 2H) • Bid 2D without a 4 card major

  5. Rebids by responder • After Stayman • Opener bids 2M • 3M = game invite • 2N = game invite (shows other major suit) • 3N = to play (shows other major suit) • 3C = sign-off in clubs (long clubs, and few points) • 3D = shows 5+ cards in bid suit, with 4 of the other major, forcing to game • Opener bids 2D • 2N = game invite • 3N = to play • 3C = sign-off in clubs (long clubs, and few points) • 3D = shows 5+ cards in bid suit with 4 of one major • 2M = invitational with 5 cards in bid major

  6. Examples • S xx H KQ8xx D QJx C xx : Partner opens 1N and you bid 2C • Partner bids 2D : Bid 2H, showing invite with 5 Hearts • Pd bids 2H : Raise to 4H • Pd bids 2S : Bid 2N • S Axx H AJ9x D AJxx C Kx : You open 1N, pd bids 2C, you bid 2H • Pd bids 2S : Raise to 4S (pd showed invite with 5 spades) • Pd bids 2N : Raise to 3N (pd showed invite with 4 spades) • Pd bids 3C : Bid 3N (pd showed 4 spades and 5+ clubs) • Pd bids 3D : Cue-bid 3H (shows great D support and a H control) • Pd bids 3N : Pass and declare!

  7. Competitive bidding by responder • Partner opens 1N, RHO bids 2H. Now what? • X = For take-out. Shows invite+ values and other suits • NT bids = As before, promise stopper • 2S = competitive, non-forcing • New suit at 3 level = 5+ cards, forcing to game
