If you bid 5♣ , LHO bids 5♦ and pard bids 6♣. P - P - and LHO tries 6♦, passed back to you. Now what?

thanks

I bid 5♣ for lack of alternatives

I just don't know what partner has, it is just a guess, but I don't think we are getting rich in 6♦X so at IMPs I'd bid 7♣

Assuming partner can be trusted, he holds the diamond Ace (or a void) plus he has something significant since he is willing to hear us bid again, so thinks we have the potential for grand. My hand, altho wide range, is not unlimited.

I am morally certain that he doesn't have a void in diamonds, and it is possible that 12 tricks are the limit. But while 6N may be the last making spot, many hands on which 6N makes on a diamond lead will afford at least some play for 7♣.

I am going to go out on a bit of a limb here and bid 7♣. In doing so, I am feeling a bit like a trapeze artist who has let go of my hold, and am now flying through the air without a safety net, hoping partner will catch me...ie have the sort of hand where we have play/are cold. I would double if partner were a non-expert.

Didn't we already show a good hand with 5♣? In order to make grand, we need partner to cover 4 losers. Yes partners hand is wide ranging (since he has no room over 5♦), but that is quite a flier on someone who just raised. We really don't know if partner is bidding to make or sacrifice when he bid 6♣. I do grant that his pass over 6♦ says something. Are we morally certain that we are in a forcing pass situation? I think we are, but it doesn't fit nicely into one of my meta rules. Is a jump over a preempt equivalent say to a 2/1 auction or a 2♣ opening where we are forced to game or to double opponents? I'm going to take the money and run with double.

IMO

• After (3♦) ?? 5♣ = 10. _X = 8.
• After (3♦) 5♣ (5♦) 6♣; (_P) _P (6♦) _P; (_P) ?? 7♣ = 10, _X = 9, _P = 4.

Partner's pass is likely to be forciing with first round ♦ control. Most of the time, 7♣ is a phantom sacrifice. If partner's control is a void rather than ♦A, however, then 6♦ might even make. On your birthday, 7♣ makes. In any case, 7♣ is a reasonable insurance policy.

[Echognome]

If partner's pass showed first round diamond control, then I'm even more apt to double than bid on to 7♣. It's harder if he is showing interest in moving on rather than doubling while holding x(x)(x).

Fairly sure Harvey would get this as a FP.

At the table, I tried 7♣. Amazingly my LHO did not grab the bait (which i think is clear) to bid 7♦ on AQxxxx,J, KJxxxx, void!

Pard held KJx QT9xxxx void xxx. The double void!

5♣ followed by 7♣ after partner's forcing pass seems pretty normal to me. Did lefty lead his singleton?

I don't think partner should pass over 6♦ with that hand... Why didn't partner show his ♥ suit ever? He had the opportunity after 5♣.
