I like 2♣ as an artificial GF after a 1♦ opening, showing nothing in particular in clubs but simply denying a 4-card major.

lol.

Whoops -- supposed to be FIVE-card major. LOL

Most I believe will not enjoy bidding 2S with this hand. Your range of 17+ must not be GF. I can appreciate why the responder was not so anxious to look for slam.

In a more simple world of 4th suit art gf,
1D 1H
1S 2C*
3C ?

if you choose to bid 3N I think the control rich hand should bid 4N (4C second choice) all of which will lead to the club slam.

Mikeh's auction sounds good to me.

1d=1h
1s=2c
3c=4c
etc.


seems like a good start if we can assume opener rebids 2nt with 4=1=5=3 shape or 2d with super diamonds and horrible clubs.

Now opener is 4=0=5=4 or 4=1=4=4.

Since opener could have Kxxx x KQxx Axxx, choosing 4♣ rather than the obvious 3N seems more than a little weird

I actually think this is a tough hand to bid. Finding the club fit isn't so hard (everyone gave beginnings to the auction but few people gave endings), but with a 4-4 fit with 31 high, including AKQ opposite known shortage, I don't see who will take the plunge.

Good point, perhaps this makes more sense? I assumed 1d can be on junk but 2c shows a good solid hand 13+-14. With less but a game forcing balanced hand one might rebid 3nt over 1s?


1D=1H
1S=2C
3C=3NT
4NT=6C?

That's a decent auction, though it has responder being quite aggressive with 14 and AKQ opposite shortness. I think either that, or 5♣ by responder and 6♣ by opener, are the two reasonable ways that one might get there. But in neither case is the last bid automatic.
