So playing a club structure, what does 1C (1S) 3D (P) 3H show?

Does it show a fit for partner's hearts? I've thought perhaps it should show a doubleton heart or a fit/slam try. Not sure how else to pick up 6-2 heart fits here.
Opener bidding 4H directly might show a fit and minimum.

I'd like to see a good Rubensohl structure if anyone has one. Or a link. Thanks

Since 2♦ is transfer for us, we don't need 3♦ as well. What should it be? 2-suiter? weak? natural slam try?

Well, suppose it goes 1C (2S) 3D P ?

Should 3H show a fit or tolerance? The point is that Rubensohl was originally conceived to combat NT interference, but strong club pairs sometimes use it as well...only opener doesn't have to be balanced and most play that 3D by responder is not GI+ hearts but GF hearts.

Conceivably 3H by opener could show anything....like diamonds or clubs or asking for a spade stopper, etc. A first step response should usually not announce a fit. It should be a relay bid or a non-fit sort of bid.

One idea of Rubensohl is to allow responder to compete at the 3-level. After a 2♠ overcall, responder would bid 3♦ with
♠x   ♥KJTxxx   ♦Qxx   ♣xxx
so opener is expected to bid 3♥ on a hand that is prepared to play there, could be stiff heart. So 3♥ non-forcing, aanything else GF.

Shvek,

From a previous thread, it appears that you use transfer over 1♥ / 1♠ and david_c was pretty emphatic about it also.

What hands would use the transfers and what are the continuations?

TIA...

Good question. After 1C (1S) it seems like a waste of space to devote the 2-level to semipositives...unless they're transfer semipositive+

Yes -- and 2 under transfers might make most sense:

(1♥):

1♠: Natural, NF
1N: ♦s
2C: ♥, natural if 1♥ isn't natural, or takeout if 1♥ is natural
2♦: ♠
2♥: ♣

=========

(1♠):
=============
1N: ♦s
2C: ♥
2♦: ♠, natural if 1♠ isn't natural, or takeout if 1♠ is natural
2♥: ♣

Now opener can accept transfer with a fit (forcing one round?) or introduce a new suit at the 2 level with a misfit and minimum hand. With no fit and no suit, opener can 2N or cue bids their suit as a general stuck bid (?)?

Another option is to limit the strength of these bids so that opener can pass with really awkward minimum hands...
