Scoring: IMP

---

South opened a strong (precision) 1♣, west bids 2♠, 3♥ from north GF, pass by east...

I simply blasted 6♥ as south, all pass, as I thought I wouldn't get useful information from bidding 3♠ (which does not agree hearts), or 5♦ exclusion, or by keycarding, etc.

[Mbodell]

what is your cue bid style and does 4♦ agree hearts? I'd expect partner to have at least 8 points and at least 5 ♥ and likely not a ton of ♦ wastage for his 3♥ call. Opposite that I'd be looking at a 10+ card heart fit with no trump losers, and first round controls in all the side suits, so my minimum point 1♣ hand is playing huge. I agree 6♥ looks quite safe. If that is the case why not bid 4♦ planning to bid 4♠ over 4♥? It may be resulting but I'd expect 1♣-(3♦)-3♥-4♦-4♥-4♠-6♥-7♥ with these hands. Maybe faster if N takes a stronger view over 4♦ than 4♥.

We play cuebidding 1st/2nd round controls, 4m here would be initially considered a cuebid for hearts. The problem with cuebidding 4♦ is that partner does not know whether it is shortage or an A/K.

Cuebidding 4♣ is perhaps best, but I was thinking along the lines that 6♥, in a sense, shows a hand that does not think that keycarding would be helpful, as otherwise I would bid a slower route. Looking at the north hand, I think the north hand should be able to infer that the 6♥ bid should have the A spades, and first round control in both minors, otherwise surely south would bid something else.

The auction might then go 4♦-4♠-4NT-5NT showing even keycards and a void, but then the grand depends on which suit south is void in....

If you are really sure 5♦ would have been exclusion for you it's clearly good.

5♦, 5♥ (exclusion, 0)
5NT, 7♥ (promises all keycards, north knows there are no losers in any suit)

There are certain cases where you can bid keycard to describe your hand to partner rather than find out about his, and this is one of them. You let him know you have the diamond void and every outside keycard, and the rest is up to him.

Jdonn is the best bidder ever.

If 4♦ is a cue bid and 5♦ is exclusion, what does opener do with xx x AQJ10xx AKQx?

And than North bids 7H and discovers, that the minor suits holdings
in the South hand are reversed.

Sry, 6H ends the auction nearly 100% of the time, and if Norths bid
7H, he better got it right, otherwise he should be silcent for the next
couple of disasters or he is dead.

One possible way to solve the problem is, that you play transfers after
the intervention, this will allow you to discover the fit and too set the fit
as trump.

Wih kind regards

I assume 4♦ is natural, I only went with 5♦ exclusion since it looks to me like the original poster said so. But yeah I don't like the first couple answers since 4♦ seems obviously natural.

I agree, I some how thought opponents had shown diamonds. I think a 3♠ cue would agree hearts then (or at least 3♠ and then 4♣/3nt if needed).
