If North when? Presumably over 5♦ ...

[Impact]

North has shown at least 65 in C & S but it is South who knows he holds a double fit.

The only issue is whether with such a good hand North should double 5H : do the right thing partner...

I would guess as South to take out insurance with 5S...but there again I would roll the dice with a double as North to confirm my strength (and As as compared with say 66 headed by KQTs and certainly would have bid the same way ue 3C & 4S with KQJTx void xx KQJxxx).

Eventhough north already showed a hand with playing strength with his jump to 4♠, I think the hand is so good that you should double 5♦ to show real power.

Anyway, south should bid 5♠ over 5♥ with a known double fit and no defence, whether or not north doubled.

These hands are an optical illusion. S thinks he is just a 4x3, but in fact he has a great hand for partner. I think he really needs to bid 5♠.

Disagree with the crowd, it's double dummy to say south should raise. North should double 5♦, and then it's reasonable for south to pull. I think raising directly is too likely to trade a plus for a minus, and the danger of losing control before clubs set up is HUGE from south's perspective so it could be a large minus.

I think bidding 5 over 5 by South would be ridiculous in the actual auction.

Agree that North should double 5♦ (or 5♥ if you like), and now South has a tough decision to make. I would still pass, but maybe could be persuaded that bidding is better.

If someone, it is South, North has shown
his hand, ... I am pretty sure I would not
have.

It will help, if you know your partner, because
you would know, how a min. hand for North
would look like.

With kind regards

I like jdonn's suggestion best but then again i was sitting south and didn't bid 5♠.

I had the hand slightly wrong - north didn't have the ♣10. I wrote the hand up at work without reference to the hand record. Maybe I also the dealer wrong.

I was playing with my regular partner so I know her style reasonably well. However we had never had an auction like this before over a strong 2♣ so I couldn't be sure how many tricks she might have to bid this way.

Here is the complete hand:

Scoring: IMP

Pass (2♣) 3♣ (Pass)
Pass (3♥) 4♠ (Pass)
Pass (5♦) Pass (5♥)
Pass (Pass) Pass

It seems to me that the decision must be close.

Swap the ♣K and ♦Q and the ♥7 and ♥9 and noone can make anything.

Not real sure how to respond to the poll... I don't think south made an error. I think north should absolutely have doubled. What if north was just dickering around trying to push them to 5? Without encouragement... there are 2 big ways that south jumping in could be wrong.

Now once north makes the obvious double, south has the obvious pull. Also, if south has shortness in both black suits, 5♥ is likely toast so multiple ways to win for the double.
