I know this is the Bridge World Death Hand, but once I show 6+ ♥ GIB should then re-evaluate and cue-bid us to slam. I misplayed the hand horribly, but I still want to be there.

Maybe GIB should cue bid, but to tell the truth, getting into cue bidding sequences with GIB doesn't seem to improve your slam bidding because the inferences and subtleties of cue bidding are way beyond GIB's programming for the most part. On a scale of 1 to 10, I put this as as 1 as far as GIB problems go. I think you can probably afford to RKC yourself and check for ♥Q.

[1eyedjack]

4H is not an encouraging bid, and may be on as few as 2. GIB might not do it, but I might raise with singleton honour in some circumstances.

From South's perspective, 5H may well be a risky spot, unless North can do something more imaginative than 4H.

So yes, North should cue.

But I also agree that this is not on the same scale as bidding a singleton Heart while showing 4. I would rate it somewhat higher than a 1, though.

[manudude03]

Are 3S and 4C even cuebids in the gib system? I know it tends to play natural in some auctions where most others would play as cuebids.

[Bbradley62]

I don't know about 4♣, but 3♠ should be a cuebid because the explanation of 3♦ precludes North's ability to reverse (3-♠).

Good question. Somebody would have to confirm the descriptions first. Advance cue bids may be beyond GIB's current programming. If I had to guess, 3♠ may be a 3NT try, and 4♣ may be GIB trying to escape 3♥ with a singleton or void in hearts and 3 or 4 clubs which we've all seen before when GIB doesn't have support for your suit.

[steve2005]

Gib should keycard, has a control in all suits (so no need for cue), has great trump support and a source of tricks in diamonds. with 1KC will be on ♦ finesse.

these are the hands keycard is designed for. and probably down on 4-0♥

[georgi]

3♠ and 4♣, etc 3rd suit from opener are natural.

And 3M still shows 5+, so opener is not aware that responder has 6+.


Once you have 5332 and not all stoppers what would you rebid on 3minor anyway?

No. South has not shown slam interest, 3♥ is primarily choice of game. So there is no way GIB can know whether slam is on or not if South showed one keycard.

[iandayre]

I don't think I agree there Helene. 3H shows 6+ and is forcing. 4H shows 6+ and is a signoff, so 3H indicates some slam interest.

Yes I agree with the majority that GIB should cuebid, and also that this is a relatively minor issue compared to many others we encounter.

I just saw Georgi's comment. Are you telling us there is no NMF or other checkback method available after a 2NT rebid? That is dinosaur bridge.

"Natural" meaning 3♠shows 3 spades (having already denied 4) and 4♣ shows 6-(4or5) in the minors?

I don't think Georgi's comment has anything to do with an auction that includes a 2NT rebid. He is saying that if Responder has (53)(23) shape and the auction goes 1m-1M-3m back to him, depending on the strength of his suits, Responder may want to rebid his 5card major rather than bidding 3NT with a completely unprotected suit.

Right, my mistake

[georgi]

And GIB plays NMF after 2NT rebid.

1minor - 1Major
2NT ->
- 3om shows 5+ cards 7+TP
- 3minor is 4+ in major and 4+ cards in opened minor 7+TP.
- 3Major shows 6+ cards 7+TP
- 3OM shows 4-4 / 5+5+ depend on hearts or spades is primary major.
