Basic Responses to 1NT (Standard)
What does a 1NT opening show?
Two criteria:
- A balanced hand.
- 15-17 HCP
Why?
- When you have roughly the same number of cards in each suit, you do not have a strong preference for a trump suit.
- When you have a balanced hand, your strength is very dependent on your HCP: so we keep the range narrow! This makes it easier for your partner to decide whether to bid and, if so, how high.
How to respond when Partner opens 1NT
Reminders: If you have 25 HCP between you, you should bid a game.
Game in NT is 3NT.
In this lesson, we will concentrate on hands where you are happy to play in NT.
Weak hands are those that cannot make game even if P has 17! They are therefore hands with 0-7 HCP. If you are weak, pass.
Invitational hands cannot make game if P has 15; but if P has 17, they can! They are therefore hands with 8-9 HCP. If you are invitational, bid the step between Partner’s bid and game and bid 2NT.
Game-going hands can make a game even if P only has 15; but even if P has 17, they cannot make a slam! They are therefore hands with 10-15 HCP. If you are game-going, bid 3NT.
Summary:
1NT – Pass = ≤7 HCP
2NT = 8-9 HCP
3NT = 10-15 HCP
How to bid as Opener when Responder invites you to game
Auction: 1NT – 2NT – ; ?
Your partner is giving you a choice based on where you are in your range.
If you have 15 or a poor 16 HCP, you have a minimum. Pass.
If you have 17 or a good 16 HCP, you have a maximum. Bid 3NT.
Deciding whether your 16 is a good 16 or not is difficult but here are some things to look for:
- As and Ks rather than Qs or Js = good
- Honours in sequences rather than scattered between your suits = good
- Honours in your long suits rather than in your doubleton = good
- Intermediate rather than low spot cards, i.e. Ts and 9s rather than 3s and 2s = good
- 4333-shape = bad
- 5332-shape = good
