What is double of 1NT?

 

 

After 2♠:

 

What is double now?

Is pass forcing?

What would 3♣ now show?

The answer to the 1st question seems easy to me, maybe because I lack imagination.

 

PENALTY.

 

I have a meta-rule, which I think is both reasonable and easy to play: after one of us shows opening values, all doubles of their natural notrump bids are penalty.

 

However, easy tho that seems (to me), the 2nd round actions for East are far from clear.

 

I would take double as extra values, no clear direction. Certainly not penalty, since we can hardly have a trump stack having made a takeout double and having everyone at the table announce values. Partner is encouraged to take this out, since prototypically one has a 1=4=4=4 14+ hand. However, partner may well hold a chunky spade suit for the double of 1N. QJ108x Kx xxx Axx looks like a double of 1N to me and an easy pass of 2♠ doubled.

 

Given that I think that double shows extras, I think I am compelled to argue that pass is nf.

 

3♣ would be natural and shows extras and I would think it ought to be forcing one round, else we have serious problems when East has a 'real' double then clubs.

 

Thanks for the post, Gonzalo. I have no idea what mainstream thinking is here, and I don't remember ever seeing this auction, tho I can't imagine it hasn't come up before.

A. What is double of 1NT? The same as 1♠ - double - 2♠. Many play this as minor-oriented, but some sort of balanced hand is fine.

 

 

After 2♠:

 

B1. What is double now? Extras, probably not four of a minor. xxx AKxx AQx Kxx?

 

B2. Is pass forcing? Huh?

 

B3. What would 3♣ now show? Clubs, probably not a dead minimum double or maybe just a 5th club.

Dbl of 1 NT just shows values, it does not need any shape at all. A.K.A penalty.

Double of 1NT shows balanced values, the sort of hand that would have bid 1NT happily. Partner is welcome to pass, or to bid a five-card suit.

 

Double of 2♠ shows extra values.

 

I think 3♣ over 2♠ must be forcing, because I can't think of a hand where I'd want it to be non-forcing. With a 1435 15-count, for example, I'd just double again.

Double of 1N shows values and 3 or fewer ♥ cards, no biddable 5-card suit, and a desire to compete

The hand that wanted to bid 3m was:

 

x

AKx

Q10xxxx

Kxx

 

I know many of you don't double with 1363, so I understand this is not even possible.
