For you XYZ bidders:

Question 1: What are your shape requirements for a jump to 3♥ over 1NT? 4H/5S? How about 3H/6S (since partner is likely to have raised to 2S with 3). Do you allow jumping to 3H with extra values but not extra shape (this hand)?

Question 2: what are your requirements for a jump to 4♥ at South's second turn? Is it a picture bid? Or just a generic sign off (since North cannot have a slam try)? I ask because it impacts the next question...

Question 3: Assuming South does not qualify for a second round 3♥ jump, and the auction continues:

1H - 1S
1NT - 2D
2NT - 3H
?

Is this a demand cue bid situation?

On the one hand South has a crappy hand .. on the other he has two aces. However any forward move he makes might overly excite North. Or possibly North should just assume there is no slam after a 1NT rebid and give up on the perfect fit hands?

Thanks!

Personally I would think that, since North has limited his hand quite nicely, 4♥ is a signoff, and thus 3♥ demands cuebids, and therefore 2♦...3♥ just shows ♥Hx with some reason for not wanting to play in NT.

I don't see why North should ever bid 2♠ on 35(32) shape, but that is just my European perspective I suppose.

Would a 2D in 2/1GF, top those hands that as alternative use XYZ?
Thus the slam tries are in 2/1 bids, not in XYZ.

It depends on how you start, if opener supports on a 3 card ♠,... For example, if you can start with 2♣ GF nat/bal/support (or some other combination) you can't have this hand. I've never thought about these sequences because with fit we show it asap.

I guess it's pretty clear that 2♦ followed by 3♥ should show something like ♥Hx with doubts for 3NT. An immediate 3♥ should probably set trumps and start cues. A jump to 4♥ doesn't make sense except minimum GF with 3 card raise (when you can't show that immediately). The only alternative I see is to use it as an autosplinter (similar to rebidding 4m).

A) for the hand shown, I'd Respond an immediate 2D! = 2/1 GF.
Edit: I want at least 4 cards in the minor .

B) For 4 card ♥ raises, I'd use Bergen and a modified Jac2NT ( even with 4 cards ♠ ).

C) There are 2 ways to show a WEAK ♥ raise w/♠ and I'm not sure what is "standard", but you could use them to distinguish between 2 and 3 cards ♥ :

1H - 1S
1NT - 2H = 4 or 5s / 2h weak

1H - 1S
1NT - 2C! ( forces 2D! )
2D! - 2H = 4 or 5s / 3h weak

D) There also are 2 ways to show a 3 card INVITATIONAL ♥ raise, and I think you could use them to distinguish between 4 and 5 cards ♠:

1H - 1S
1NT - 3H = 4s/3h invite

1H - 1S
1NT - 2C!
2D! - 3H = 5s/3h invite

E) And with a GF 3♥ raise and NO 4+cards minor :

1H - 1S
1NT - 2D! ( artificial GF )
2NT - 3H = 4+s/3h, GF
