double

[gwnn]

1♣-x-1♠-p

2♣-2♦-x

 

why?

Usually when three suits have been bid double is penalty. Also usually when partner has shown a one-suited hand (i.e. opened a preempt, or here similarly 1♣...2♣) double is penalty.

 

Of course, a penalty double here is more likely to be based on a misfit for clubs and good general values then on a big stack of diamonds, and that's how I'd read it in this auction. Opener can still pull with (say) three-card spade support.

This is a low-level, non-power auction.

 

Double for me is just 'cards'.

Yes. My agreements say double is penalty once one player as 'defined their hand' e.g. by opening a pre-empt or by a rebid.

Comment 1: This isn't a sequence that I've ever discussed in any serious partnership. As such, I'd expect a meta rule like Adam's to apply in which case, the double is penalty (with the except of when I am playing with Sue in which case all undiscussed doubles are for takeout)

 

Comment 2: Our opponent has doubled and then bid a new suit. This generally shows a strong hand. If you're a Canuck it shows a very strong hand. A case could be made that the chance of holding a hand suitable for a penalty double during this sequence is fairly slim. It might make sense to specifically redefine X as takeout oriented.

The main question that you should ask yourself when you define in your partnership a low level double as penality should be: Is there another way to express a non penality invitational plus hand without direction (for example a hand with which you would have bid yourself a 2♦ nmf)? Here the obvious answer is no, so double should not be played as penality

I don't understand a takeout double by the partner of someone who has rebid their suit. What shape is it supposed to be, 5422? That seems like a teeny target for which to reserve the double. Penalty all the way, doubler's partner is broke and has nowhere to go.

[pclayton]

If the auction went:

 

1♣ (x) 1♠ (p)

2♣ (2♦) p (p)

dbl

 

what kind of hand would you expect?

It's not clear to me that there's that much of a distinction between takeout and penalty actually. I think the prototype shape for the first double is something like:

 

5431

5341

4341

 

In each case responder has some diamonds, and probably an honor. He's not expected to be sitting on a five-card diamond suit, or something like KQJx... the double is just an announcement that "hey, I don't think we have a fit, I have a good hand and a diamond card, maybe we should defend doubled."

 

For opener's double I'd expect something similar -- a maximum 2♣ rebid and probably some shape like:

 

1336

1345

2236

 

Again it's an announcement: "hey it's our hand, I don't think we have a fit, I have a good hand and a diamond card."

 

Perhaps "cooperative" is the best name for these. I don't expect them to be left in by a partner who has singleton diamond or unacknowledged three-card support for partner. But they will be left in more often than not. They certainly don't imply "shortage" in the suit doubled (but three cards is quite typical).

I'd argue that double shows some degree of flexibility:

 

A fifth spade seems certain, along with doubleton club (maybe three clubs)

 

5=3=3=2

5=4=2=2

5=4=1=3

5=3=2=3

 

all seem reasonable.

 

Spades out-rank Diamonds, but Clubs don't

It seems reasonable to have methods that permit exploring a spade fit

[kfay]

I doubled on this hand. Thought it was penalty but was certainly fine with going on.

[dake50]

What's left to try for? 3-fit for S? 2-fit for C? 4-fit for H? stop in D? =do it!

Defend 2D. I don't see much else that has a clear message.

[whereagles]

This obviously depends on agreements. In Robson/Segal agreements, it's a take-out. Likely shape: 5332/5431 and 9+ hcp, probably with some defensive values. (A 2♥ bid would show an offensive 54 or a 55.)

This is how I would take it. I think Adam is saying the same thing too.

Hi,

 

t/o.

 

Why? Matter of partnership agreement.

Playing standard, I would say the double is

penalty.

 

With kind regards

If the auction went:

 

1♣ (x) 1♠ (p)

2♣ (2♦) p (p)

dbl

 

what kind of hand would you expect?

I posted this because I thought the answer was obvious. How can this double be anything but takeout? And if this double is takeout, then I find it odd that a double in the OP problem would be thought of as penalty.
