Match points, unfavourable.


4NT = RKCW
5♦ = slam, try with diamond control
5♠ = asking for diamond control.
5NT = Grand slam force

You need to describe what signals are being played, E's card at trick one can mean various things.

Is partner's most likely hand not ♠AQJxxxx + 6 small cards? It obviously depends on pre-empting style but if they had an 8th spade or a red suit king, would that still be a 3♠ opening? If not then we basically need to find out if partner has ♣Q or not. If anyone has good methods for that I would love to hear them but I cannot think of an easy way off the top of my head. Nor can I see how any of the presented systemic options helps very much in differentiating between ♠AQJxxxx ♥xxx ♦x ♣xx/♠AQJxxxx ♥xx ♦x ♣xxx and ♠AQJxxxx ♥xxx ♦x ♣QJxx, should the latter not be a 1♠ opener.

Of course, if a red suit king is a perfectly good hand for 3♠ that changes the equation completely. Seems like a bidding problem where we need more information before engaging...

I think I may have stumbled upon a bug in the hand. I landed in 6S after going through RKC. I played for hearts to break 5-1 and the hand with the singleton to win the third diamond. I played for an elimination and when I pitched one of my hearts on the third diamond, West won and gave me a ruff+sluff instead of returning his heart.

Is AJ98xxx and a card (be it a spade, a K or Q♣) plausible ? Also a singleton diamond and non singleton Q♥ may well be good enough. Or QJ9 8th and a K. Even ♥Jxx could be enough.

I'm inclined to give nothing away and just bid 6♠.

I rank
  • 6♠ = NAT. Daisy-picking might help opponents,
  • 6N = NAT. Might avoid ♦ ruff,
  • 4N = RKC. Exploring unilkely grand.
  • 5N = Optimistic.
  • 5♦ = Pointless.
  • 5♠ = Pessimistic.

I think 6S directly is best as it makes it more difficult for the opponents to find a 7 diamond sacrifice.

Thanks I was wondering how someone made a slam.

The play should had been irrelevant as nothing should work for 12 tricks.

Yes, but it does affect which failing line you take.

I'm starting with 4 NT RKCB. I'm almost sure partner is likely to have the ♠ A, but after 5 ♣ I may be able to glean more info about the hand by asking about the ♠ Q. Otherwise, I'll settle into a 5 level contract.

If perchance partner doesn't have the ♠ A, I'll settle into 5 ♠ figuring that at unfavorable vulnerability partner isn't bidding 3 ♠ on QJ9 seventh and out.

If 6♠-1, then partner doesn't have their bid!

4♠ looks obvious to me. AQJxxxx plus a king is a one-level opening.
... that would still not be conclusive proof, before someone wants to explain that to me as well as if I was a 5 year-old. - gwnn

For those who didn't care to click, the winning action was to bid 4NT + trump queen ask to play 5NT

sadly in my partnerships 5nt isn't the right response to a queen ask. i play that as showing soft extras.

If partner is a sensible and disciplined player,his vulnerable pre-empt promises
7 playing tricks in spades(the rule of 2 and 3) As you have 5 quick tricks and good spade support,you should
bid 6 spades direct.
