Not sure if this is a B/I problem, but I had the following sequence with a very good player that I had not played with before.

Natural or cuebid, in a 2/1 setting:

1♥ - 2♦
2♥ - 2♠
3♦ - 4♦
4♠

Cue.

The Cue should promise a top honor, since it is partners suit, and it is
also a good idea, that the first cue in general showes a honor.
The cue does not deny AK in hearts, p should assume that there is a
heart control, if he needs a heart control.
So the 4S is also kind of natural, ..., sort of.

But there is a 3rd meaning: 4S showes 1KC, lots of players play 4D as
Key Card ask for diamonds, and I would be more worried, that p did
intend 4D as keycard ask.

With kind regards
Marlowe

PS: Having read Han's response - for me 4H would also be a cue, promising
a good suit, a source of tricks, so in the end, it is also a suggestion play there,
but it would be a cue for us. Oh, and we also dont play minorwood.

4H would be a suggestion to play there, 4S is a cue.

It doesn't make sense to propose playing in a 4-3 fit at this point. But holding xx AQJ10xx Qxx Qx it would be a shame if you couldn't play hearts anymore.

I think that 4D as keycard ask is a terrible agreement for this reason and others. Also, you should discuss whether 4D denies a club control. If so, 4S should show a club control.

Good. I'm not going crazy then!

Responder has at most two hearts maybe fewer, exactly four spades, and five or more diamonds. Opener has three or fewer spades, 5 hearts and 3 diamonds OR 6+ hearts and 3-4 diamonds. 4S is cuebid. If opener has a soft hand with six or more hearts and only three diamonds, opener could have bid 4H as a suggestion to play. But 4S cannot be a suggestion to play.

Worst case scenario, responder can just have a spade fragment instead of a suit, with concentrated values in spades and diamonds, no heart support, no club stopper, and no six-card diamonds, something like KQx-xx-AQJxx-xxx where no other bid makes sense unless systemically required to bid NT even with one suit wide open [I would not like it].

I'd like to see the hands.

I'm not 100% sure the hands are useful here, as opener had a very sub-min...

Wow! even I would not open that rubbish. 1H, 3D and 4S all seem to be highly dubious bids.
