I found this difficult:
1S-(2H)-3D
3S-?
We have agreed that 3D is natural and almost sure that responder has no 3cS (2NT, 3H, 4C, 4D, 4H are all S-fits).
We also have agreed that 1S-2D-3S-4D: 4D=cue for S.
- Is 3S by opener forcing?
- What is 4C, 4D and 4H now.
It seems to me that
1S-(2H)-3D
3S-4D
Opener didn't promise good Spades or extras, so this is really different than:
1S-3D
3S-4D

1S-(2H)-3D
3S-4H
- What is responder asking and what is 4NT by Opener now? Is it to play?

1S-(2H)-3D
3S-4H
4S-4NT
- 4NT is RKC. For D or for S?

FYI below the 2 hands and the bidding, but I'm more interested in the more general questions above.

3d is forcing to game. Openers 3s is a good 6-card suit (would bid 3h to "punt" without a clear call) but it isn't a jump and does not set trumps. Responder can bid 4d next to set the suit; 4h over 3s would be a raise to at least 4s with extras ( better than 4s bid). I'd have bid 3nt over 3d with the actual hand; this is too likely to be the best contract on the south cards to bid 3s (north will rarely have a heart stop give the over call and KQxx with south).

3♦ is game forcing if you don't play any gadget, and 4♦ shouldn't be a cuebid with fit in spades, this hand is best example for why.

I would recomend that you tak a look for transfers after opponents overcall 2♥/2♠ over 1x opening

Completely disagree, if you don't know how to bid in a game forcing auction where all bids except cuebidding the opponents suits are natural, then you shouldn't try to solve this by adding a specific gadget. The same issues (e.g. cuebidding their suit at the 3-level is a punt with no clear diction) will come up in many similar auctions.

I don't believe rebidding diamonds "sets the suit", it is just a natural bid with extra diamond length. Otherwise I agree with everything.

Thanks for the answers!
Keeping it natural, do you agree with the following?:
1S-(2H)-3D (3D=GF)
?
3H=nothing to say: No 6cS, No H-stop, No 4(3)c-D (Not sure you would always bid 4D with 4cD at MP's)
3S=6cS
3NT=Stop H
4C=Natural, 5cC
4D=Natural, 4(3)cD
4H=D-fit, Splinter
4S=Good 6(7)cS, Extras (Or Fast arrival, So minimal??)

1S-(2H)-3D
3H-?
3S=3cS, Good D, slam-interest
3NT=To play, Good D
4C=natural
4D=natural, 6cD, slam-interest
4H=Cue with S
4S=to play, 3cS, good D
4NT=RKC for D (with S bid 3S first and 4NT later)
5D= to play

1S-(2H)-3D
3S-?
3NT=To play, Good D
4C=natural
4D=natural, 6cD, slam-interest
4H=Cue with S
4S=to play, 3cS, good D
4NT=RKC for S (with D bid 4D first and 4NT later)
5D=to play

1S-(2H)-3D
3S-4D
?
4H=Cue for D
4S=to play
4N=RKC for D

1S-(2H)-3D
3S-4D
4S-?
4NT=RKC for D (This is the way to go to RKC for D?)

This just shows a doubleton spade, ideally Hx. That way you can find good 5-2 spade fits when you don't have a heart stopper.
