Responding to a 1NT Opening Bid -- Balanced hands (Pass, 2NT or 3NT Only)

When partner opens 1NT you know they hold either 15, 16 or 17 HCP (High Card Points) with a balanced hand. If you hold a balanced hand also you want to play in NT. All that is left to determine is whether or not you want to play in a part-score, game or slam. Add your points to partner's to determine where you want to play. Remember there is no point in bidding any higher than 1NT if you know you cannot make a game.

To make game in 3NT you need between 25 and 32 HCP.
When responding to partner's opening 1NT this table will help guide you as to what to bid:
Responder has a balanced hand with: Responder bids: 1NT opener does this:
0-7 HCP Pass -
8-9 HCP 2NT Pass with a minimum (15 HCP)
Bid 3NT with a maximum (17 HCP)
10-15 HCP 3NT Pass

Let's look at some examples:

Example 1

♠KQ3
♥84
♦A732
♣Q532

I have 11 HCP with a balanced hand and partner opened 1NT. Since partner is balanced and I am balanced we probably want to play in NT. If partner has 15 HCP, together between the 2 hands we have 26 HCP. That is enough for a game in NT. I want to be in 3NT. If partner has 17 HCP, together between the 2 hands we have 28 HCP. That is enough for a game in NT. I want to be in 3NT. So no matter what partner has I want to be in 3NT. My response to partner's opening bid is 3NT.

Example 2

♠K93
♥84
♦A732
♣Q532

I have 9 HCP with a balanced hand and partner opened 1NT. Since partner is balanced and I am balanced we probably want to play in NT. If partner has 15 HCP together between the 2 hands we have 24 HCP. That is NOT enough for a game in NT. I want to stay low in the bidding. If partner has 17 HCP together between the 2 hands we have 26 HCP. That IS enough for a game in NT. I want to be in 3NT. Now I am going to have to ask partner whether or not they have 15 HCP or 17 HCP. My response to partner opening 1NT bid is 2NT. This says "Partner, I am interested in a game in NT. If I was not interested in a game in NT I would just 'Pass' and let you play in 1NT. However I cannot quite bid the game myself -- I don't have enough values. I know you could have 15 HCP (in which case you should Pass my 2NT) but I also know you could have 17 HCP. If you have 17 HCP I want you to bid 3NT and we will have a good shot at making game."

There are quite a few examples. Do not feel you need to do all the examples right away. Do a few and come back to them if you want. But I'd rather give you 56 examples and have you quit after 8 rather than give you 8 examples and leave you wanting more! Could I have made a mistake in some of them? Absolutely! If you feel there is an error in the point count or bid, just leave me a message. My editor can be a bit lazy at times so this is more than likely to happen.

On each hand first state how many HCP (High Card Points) you have.

Add your points to partner's if they have 15 and determine where you want to be.
Add your points to partner's if they have 17 and determine where you want to be.
If the answer is the same, that is your bid. If the answer is not the same, you probably need to invite game.

So first state how many HCP and then say what you would bid if your partner opened 1NT and the opponents "Pass".

What do I do over 1NT?

Hi Heidi,

What do you suggest South respond to North's 1NT and what would be the rest of the auction?

All vulnerable, West is dealer:

North
♠J8
♥AK98
♦A92
♣K854
West
♠T963
♥JT97643
♦Q7
♣A
East
♠7542
♥52
♦T643
♣J72
South
♠AKQ
♥Q
♦KJ85
♣QT963

N E S W
Pass
1NT Pass ???


Heidi's Answer:



I think this can go a few different ways.

Option 1:
South can look at their hand and just say "You know I think we have a slam. But since we don't QUITE have the values (maybe) I should just check for Aces."

If they do that South can bid 4♣ (Gerber) to ask. North will show two Aces and South will bid 6NT.

This is breaking one of the rules about asking for Aces. You are not supposed to do this unless you have first or second round control of all the suits. But you are stuck here and have to take a chance.

Option 2:
If South just wants to invite slam on high card values alone they can bid 4NT. North will "Pass" since they are minimum.

Option 3:
More experienced players have ways to show their distribution but I don't think anyone reading this blog will be able to do that.

Should South be concerned about their singleton Heart?


Ideally "yes" they certainly should be concerned. They have no idea they are not off the cashing Ace and King of ♥.

Is there any way to find out about either one of those cards?

No. I thought not.

The same with the ♣ suit. You could be off the Ace and King of ♣. But again, HOW do you find out?

So in reality don't worry about that -- if it happens, it happens. I'd be more worried I'd missed a slam. That is the big worry for me.

Recommended Auction (which is not really recommended since it does contain some flaws!):


I think that South should just count extra for their extra distribution and ask for Aces. When they find out the partnership is only missing one Ace take a chance on 6NT.

North will have to set up that ♣ suit. If East leads a major or a ♣ it would be easy. They will win a major suit lead in Dummy and play a ♣. West will have to win their A♣ and now North has 12 easy tricks.

On a ♦ lead North will have a harder time since they will probably win the trick in their hand. Who knows what will happen then.

Climactic finale

Playing matchpoints. You are vulnerable. The Opponents are not vulnerable.

Here is your hand:
♠AQ84
♥AK9
♦K954
♣J4

This is the thrilling conclusion to this hand.

So far the bidding has been:
Opener US!
1NT 2♣
2♥ 4NT

To review. Partner opened the bidding 1NT. WE had a 1NT opening hand! WOW! So since we do have a four card major we started with Stayman. Partner has to respond. Partner responded 2♥ to let us know they have four ♥. We didn't have a fit there so bid 4NT to find out if Partner was minimum or maximum -- plus we were secretly hoping they would be able to support our ♠ suit. Over our 4NT bid Partner says.....

5NT.

What they heck? That isn't even a response!

What is your bid? What do you think Partner is showing? Maybe think about what they DON'T have. Might make it easier.
