As an aside, our responder has a way to ask opener's shape after 1D-1H, 1N.

More important, responder has a way to show approximate shape after 1D-1M, 1N. For example...

1D-1H,
1N-2D,
2H-2N,
3C-3D

shows 4H, 5+D and short spade. We assume 1453 but it could be 1462 or 0463, etc.

We use relay points (queen points) and parity cue bidding for other relay auctions. Should we do so here?
Opener could ask for QPs and then ask where those points are located.

But we have the problem of an assumed shape. Plus responder may be aware of a 6-cd suit (especially a major) and thus a fit that opener is unaware. Also, what would the base QP be?

I think we probably can't avoid co-captaincy, but looking for ideas for either captaincy or co-captaincy continuations.

You should probably also tell us what Responder has shown since they are not just using the cheapest bids each time. Since you are only at 3♣ I do not understand why your next relay could not ask for exact shape - 3♥ = 1453; 3♠ = 1462; 3NT = 0463; or whatever. Then you can get back into your QP relays with shape known.

Well, we have the room to show a little more shape ending in this instance, but

1D-1H,
1N-2D,
2H-2N,
3C-3S would show 4H, 5+D, and short club

Basically, we show "assumed shape" of 5431, 5521, 4441, 6332, and 6331 and exact shape of 5422
