1♦. Automatic.

My partnership never violates our "no singleton / void in 1NT opening hand" rule.

[DavidKok]

I would open 1♣, but I understand that people might wish to open 1NT, especially if their agreements over the 1m-openings aren't as well practiced. I would not open 1♦ and prefer not to play a style where that is the recommended opening.

[mw64ahw]

1♦ whatever system I play

What do you bid over 1♣-1♥-1♠-1N ? and if you feel you can pass, what do you do if it's a touch better ?

We would always open 1♦.

[DavidKok]

I play(ed) Dutch Doubleton, which resolves this nicely. In standard I think it is percentage to pass 1NT on that auction, partner is showing 6-9 with hearts and our hand is an OK 16 but worth a downgrade because of the 4441 shape and the shortage opposite partner's length and misfit in both black suits.
On this example hand I am not too worried about that auction. 1♣-1♥; 1♠ shows an unbalanced hand, either 4=1=4=4 or 4(+)♠5(+)♣. Partner bidding 1NT rather than 2♣ means partner is not worried about diamonds, which is not that likely given our holding.

If the hand is stronger I will raise 1NT to 2NT, and if it is even stronger I can bid 2♦ 4SGF. This last option caters to finding a diamond fit, though I rarely expect this to be relevant.

The problem auction is: 1C-(1S)-Dbl-(Pass)

But I will also tend to prefer a 1C opening rather than 1D.

does dutch doubleton skip longer diamonds to bid a major like many of the americans do ?

What does partner do with x, Axxxx, Jxxxx, Kx ?

[DavidKok]

It does, though it also requires 8+ HCP for the 1M responses to 1♣. The auction would be 1♣-1♥; 1♠-1NT(!) showing 8-10 and now opener will take another bid with 16.
Dutch Doubleton uses the 1♦ response to 1♣ as a multi-meaning bid. The way I played it the bid was 4-way, but the 2 most important meanings are 'natural diamonds' and '0-7 most hand types, with some specific exceptions that have better alternatives'.

[pescetom]

I'm happy to open this 1NT with a partner who is on the same wavelength, and not because we lack experience or agreements over the 1♦ opening.
Otherwise it is 1♦ (which does not deny those clubs) and now I'm not so happy: we have robust agreements if partner gets to bid 1♥ or whatever, but any major-oriented bidding on the left could be awkward.

[smerriman]

If I open this 1NT I always seem to end up playing in a 5-1 fit. Just 1♦ for me.

4S

[pescetom]

If 2♠ is purely natural then 4♠ seems automatic. But if it's the weak option of Rubensohl or whatever then I'm not very optimistic about making ten tricks: not going to get very rich by doubling either, but at MP I feel obliged.

Possibly not the best board to start my adventures with offshape 1nt openings with, but it was fun.

[P_Marlowe]

After 1D you reach 4S via the seq.

1D - (1H) - 1S (1) - ...
4S (2)



(1) The 6th spade is more than enough to compensate for the missing 6th HCP
(2) assuming 1S showed 5+

[jdiana]

1NT is not a legal bid under ACBL rules. I guess you can do it if you're just playing for fun, but I would only do it to solve a real rebid problem, which I don't think you have here. Just a simple 1♦ for me.

[mw64ahw]

I don't 'love it' - you can play 1N with a stiff honour which gives a touch of protection after a transfer followed by Pass.
Also, this hand plays as a 18+ so 1N is an underbid; this is why 5♠ makes on a hand that is barely worth an invitation.

[jillybean]

Did you miss my comment up thread "Having some fun , online , with a good p. It’s a good time to test the 1nt waters." ?
I'm experimenting with 1nt openings, txfer walsh and other things, having some fun while learning.

It's not legal in ACBL, you can open 1N with a stiff A,K or Q, not a J . This was not an ACBL game. At the club, I doubt anyone would care.

[mw64ahw]

Fun when it works, perhaps not so much when it doesn't
