1♣ - (P) - 1♦ - (1♠)
2♣ - (P) - ?

You are responder with ♠xx ♥KJx ♦AKQxxx ♣xx
System is vanilla 2/1, scoring IMPs, don't remember vulnerability.
Openings are relatively sound -- partner doesn't have 11 HCP unless the club suit is exceptional.
I think double by opener would be support (it certainly would be if I had responded hearts)
I'm pretty sure 2♠ is just generic force here. We have successfully used Western cuebids at the three level.
I also don't know if 2♥ promises 4 or just shows heart values. For certain, partner knows that after 1C-(P)-1D responder will only have a 4 card major if also has game forcing values.

In any case, using YOUR methods, what is your call and what is your plan for various rebids? (assume no further interference)

Unless you play 3♦ as forcing, which few do, though Pavlicek has good arguments for playing it that way, what else can you bid besides 2♠?
2♥ is an option but it is a bit eccentric.
I prefer 2♠ follwoed by 3♦ if possible.
If partner than bids 3♥ over 3♦ you might raise.

2♠, then raise 2NT to 3; bid 3♦ over 3♣; raise 3♦ to 5 and 3♥ to 4.

Using my general methods (sort of), partner would have doubled with 4 hearts, so I bid 2♥ showing values there but not always 4.

Using my actual methods, 2♦ is an artificial inv+ force so I use that.

I would have bid 2♦ on the first round - but then I am a dinosaur who has not given up SJS at the 2 level. What would you have bid in an unopposed auction which started 1♣ 1♦ 2♣?

No strong jump shifts, no inverted minors so we have the immediate 2D defined as a game forcing club raise with no major suit shortness. It never comes up.
In the unopposed auction 1C-1D-2C I would rebid 3D not forcing and expect to miss some games. With a couple more points I might try the idiosyncratic 2H.

Does my 2♠ force to 3NT/higher?
opener has Jxx Qx x AKJxxxx

I like double showing 4 hearts (rather than 3 diamonds) might be the only way we find a 4-4 fit (or even a good 4-3) fit.
OTOH we are used to support doubles so I'm hesitant to suggest an exception for this specific auction

I also agree that perhaps 2D is better as artificial..
Can you give a quick summary of continuations or refer me to somewhere?

[Zelandakh]

Now Opener bids bids 3NT to show a half stop and Responder's 4♣ ends the auction.

It is possible to agree that X always shows hearts when they bid 1♠ over our 1m. If you do this then it would be support that is the exception.

Ah, a delayed NT bid to show a half stop. This isn't something I thought about while mulling over this auction. very cool.

The original idea for the relay after 1m-non jump in suit-2m is sometimes known as a Bourke relay (which you can google), but we adapted it and home hashed the responses. I believe for Bourke, the relay would be 2♥ as we've bid diamonds (not 100% sure), but we use the suit above partner's regardless of whether we've bid it or not. In it's original form it was treated like 3rd suit forcing as an analogy to 4SF.

The only thing you have to remember in our scheme is that 1♣-1suit-2♣-2N shows diamonds invitational (or more diamonds but still inv if you already bid them), if you have a standard 2N inv bid you go through 2♦.
