1NT Opening: When Not to Open 1NT
1NT is a very useful bid when it applies, it says a lot about your hand. But like most bids in bridge, it needs to be used correctly, not over used or underused.
The key features of 1NT is that it shows 15-17 points (depending on your agreed system, but that is the common range), and a balanced hand.
Main reasons not to open 1NT
Do not force 1NT when:
- you do not have 15-17 HCP,
- your shape is too unbalanced (especially when you have a singleton).
Make sure to have the right shape
Hands with singleton/void are NOT 1NT hands. Although, it is okay to open 1NT with a singleton King if in every other way the hand looks like a 1NT opening. But don't do it with a singleton Ace.
It is fine to open that 1NT, it is a modern idea but it is becoming quite popular
On this hand we would not consider opening 1NT, it is 100% certainly a 1S opening, why? We don't push excessively to open 1NT, this is a lovely hand to open 1S, it is distributional with good suits. If partner raises you may very well end up in a spade game, and you will find this hand plays well - it is not suitable for No trump if you have a major fit.
Make sure to have the exact strength:
There is no reason to push to open 1NT if you don't have the right strength. It is okay to upgrade a 14 point hand with a nice 5 card suit, that is probably the only time to vary away from 15-17 (or your partnership agreed strength). Overall, it pays to be exact, no need at all to stretch - you don't gain by opening 1NT without the right type of hand.
This would be a fine 1NT hand to open. It only has 14 high card points, but what it slightly lacks in high card points it makes up by having a very decent 5 card club suit - 5 card suits typically make a lot of tricks. Add +1 point when you have a respectable 5 card suit, that will allow you to open your 14 point hands 1NT sometimes!
Why this matters
1NT is a bid that signals to your partner that you are balanced with a certain point range - partner will now help steer the contract to a sensible contract, only if that information is accurate. Its quite simple, you will probably end up in the wrong contract if you are not accurate when opening 1NT. You will likely end up too high, or in No Trump when you should be in a suit contract!
Common mistakes
- Opening 1NT because its simple and easy, even when you don't have the right strength
- Pretending your hand is balanced enough when its not
- 5332 hands should be opened 1NT if they are in the correct point range - a common mistake is to open those 1 of a suit, for example 1♥ instead of 1NT.
Practical checklist
Before opening 1NT, ask:
- Is my strength exactly in our range?
- Is my hand balanced enough for NT?
If any answer is no, pause before choosing 1NT.
Final takeaway
Always try to be accurate, don't do anything you know is wrong. Just pause for an extra moment and figure out what the alternative is.
1NT Opening for Beginners: What the Bid Promises
A 1NT opening is powerful because it is very descriptive in one call.
When you open 1NT, partner expects specific information immediately.
Why this is so useful
The appropriate level (its usually easy to see straight away whether to invite or bid game, or just settle for partscore
Have an idea of what suit contracts might be reasonable or not - with the knowledge that partner is balanced, we can glance at our hand and often say something like "I'll use stayman to check for a 4 card major, if not 3NT will be our best spot". You cannot confidently say that when partner opens anything else since their range of hands can be so big. For example, if partner opens 1♣, they might have 3 card clubs or 8 card - you couldn't confidently know what the correct contract could be.
Balanced shape reminder
TLDR: balanced hands do not have a singleton - that is the main indicator.
Balanced hands are typically:
- 4-3-3-3
- 4-4-3-2
- 5-3-3-2
No void, no singleton.
Common mistakes
- Opening 1NT outside agreed range.
- Opening 1NT with a singleton.
Your first bid is often the most important, it sets the foundation for the rest of the auction - do try to get it right!
Final takeaway
1NT is a bid that works really when it is appropriate - it sums up a lot about your hand in a single bid. The goal of bidding typically is to tell partner as much about your hand as possible, and when a single bid achieves that, its a great start. However, if your standards are flexible and you open 1NT when you shouldn't, or avoid 1NT when you actually should've opened it, you won't get the benefits of the bid.
In summary, try to be accurate where possible, take a breath and pause for a moment if you're unsure.
