Bidding practice, but let's say red@imps.

1♠-2♣ 11-17, 5+♠-GF relay
2♠-2NT 15-17 with ♦-relay
3♣-3♦ 5-4 - relay
3♠-??? 5143 - ???

You can do the following:

• bid 4♦ terminator to sign off in 4♠
  
• bid 4♦ terminator to sign off in 5♦
  
• bid 4♠, slam invite
  
• bid 5♦, slam invite
  
• bid 4♣ (puppet to 4♦) then 4♥ RKC for ♠
  
• bid 4♣ (puppet to 4♦) then 4♠ RKC for ♦

We don't really have a clever spiral ask after the bottom two options, I guess we should...

We are missing appr 10 HCPs, with a little luck that includes most of ♥KQJ ♣QJ so we have almost everything else. So I want to be in slam. If I can't verify both ♠KQ and ♦K (or, alternatively, ♠K ♦K ♣KQ) I am not going for 7. I think I'll just blast 6♦.

AQJxx x AKxx xxx is an excellent grand slam, and so is AQxxx x AKxx Kxx. Axxxx x AKxx KQx is OK too. Can I agree diamonds, hear about three keycards, and then bid 5♠ as a grand-slam try?

[Cyberyeti]

You have the space, you should have a way of making a 6-ace ask.

With the system given, I keycard in spades then bid 5N over 2+ which hopefully asks for a side K other than hearts which I could have asked for by bidding 5♥, if partner bids 6♣ I bid 6♦ which I would expect partner to raise to 7 with the K.

[Mbodell]

I'd key card in diamonds, and assuming 3, then I'd king ask. As long as he doesn't show the ♥K I think I want to be in 7♦. If he has the K of clubs I want to be in 7♦ (not guaranteed, but quite likely I think since partner will of shown 14 and any of ♠Q or ♣Q should be enough to make spades good on reasonable splits, and if neither of those a black J is good enough for a finesse at worse for the same). If he doesn't have the K of clubs or hearts then he has 11 points from ♠A and ♦AK and the missing cards are ♠QJ, ♥QJ, and ♣QJ and he needs at least 4 points. The spades are each 4 times as likely as the hearts and 4/3 as likely as the clubs based on his shape and known cards.

Partner had a slightly unhelpful singleton heart:

AJxxx
K
ATxx
Kxx

And spades and diamonds were both offside (I keycarded in spades for what it's worth). Oh well.

That hand belongs in Bridge Hell, that's awful to bid a very nice slam that goes off.

[the hog]

Opener should not count the stiff H as part of his 15 count, but should downgrade the hand. Also 3S is awfully high for showing a 1345 shape.
