Suppose you are playing 2/1 and your auction starts:

1♠ - 2♣ - 2♥

When responder has 3+♠, he can bid 2♠ next and you're in a very good position to look for slam. Opener can pattern out and you're still low enough to have space for control bidding and serious/non-serious before you get to 4♠. In fact this is so good that it might be worth bidding this way even on hands where you'd normally bid Jacoby 2NT or the like (since you get more/better information by starting the auction lower).

However, things are not nearly so good when responder has 4♥ (and fewer than three spades). If you proceed with the normal/natural 3♥ call, you've consumed a whole level compared to the auction where the fit is in spades. You still have a bit of space, but you're not going to be able to get both opener's shape and control bidding in before you get to 4♥.

In fact, it seems like you might do better to bid 2NT with a heart fit, expecting that most of the time opener will pattern out with 3m (or 3♥) and you can set the suit then and/or start control bidding. But this will occasionally get you in trouble, either because opener rebids 3♠/3NT (taking up a lot of space and muddying the waters as to the trump suit) or because opener decides that you cannot really have four hearts on this auction and are instead scrambling for a game.

Does anyone have good methods to suggest here, when our side's fit is in opener's second suit (or for that matter, responder's suit)?

Did I misunderstand or do you mean we would do better using 2nt to show 4♥ gf?

Much may depend upon whether (and how) one plays Neb 2C, but howz about a variation on JLall's 1M-1N-2x-2N = Lebbish suggestion? So

1S-2C-2H-2N-3C-?3D = 1=3=4=5 or 2=2=4=5?3H = strong H raise?3S = S raise, either extras or min or very good S (contrast with 2S immediately)?3N = suggestion to play?4C = slammish?
Then 1S-2C-2H without 2N Lebbish:2S = S raise, either extras or min or very good S (contrast with N Lebbish treatment)?3C = C3D = 1=3=4=5 or 2=2=4=5?3H = min H raise?3S = something opposite of the 2S raise, with some I've played this as Serious?Non-Serious, whichever3N = suggestion to play?
Many possibilities....
Somehow I can't separate the alternatives to the next line....

I haven’t thought through all the potential sequences, and the devil is always in the details but here’s an idea:

1S 2C 2H 2N.

If by agreement 2N can contain 4 hearts, have opener bid 3D as a checkback. Responder bids 3H with 4 and something else, presumably usually 3N, with fewer.

But this simply delays getting to 3H, so we need to break our heart rates into no slam interest and slam interest. I think it is probably best for the slow auction to promise mild interest.

1S 2C 2H 3H shows 4 hearts with a hand that has no slam interest, but of course opener is unlimited so slam remains possible. Opener knows not to make a try without a very useful hand. Gong through 2N shows slam interest.

This method may make life difficult when opener is 5440 and responder is 2=2=4=5 or 2=3=4=4 and a diamond contract is best but this will happen rarely.

One wrinkle is that sometimes opener is 5413 so wants to bid 3C. Is responder’s 3H now hearts or a cuebid for clubs?

I'm not suggesting that. I'm suggesting that since 2NT is forcing (and nominally natural), you can often temporise this way. For example compare:

#1: 1♠ - 2♣ - 2♥ - 2NT - 3♣ - 3♥

Here you know that opener has 5413 or similar (thus short diamonds), you set hearts at the three level, and can now start cuebids.

#2: 1♠ - 2♣ - 2♥ - 3♥

You obviously have less information about opener's shape and you're at the same level of the auction. This seems strictly worse than #1.

However the danger is:

#3: 1♠ - 2♣ - 2♥ - 2NT - 3♠

Now you know opener is 6-4, but opener doesn't know what trump is. If you cue 4m, partner will probably assume spades are trump. So you might be worse placed than if you had auction #2.

Of course it's also common to see:

#4: 1♠ - 2♣ - 2♥ - 2NT - 3NT

If you bid 4m, will partner know that this is a cuebid for hearts? That might actually be a good agreement since nothing else makes a lot of sense. But I've never discussed this with any partner. You've also lost serious/non-serious in this auction since 3NT was just natural (assuming a normal 2NT call).

If I'm going to actually suggest something, I'd go with using the cheapest call as a relay and letting the next call show the fit with opener's first suit. So we'd have:

1♠ - 2♣ - 2♥:

2♠ = relay, asking about opener's pattern, less than 3♠
2NT = 3+♠

The relay sequence can be used with a heart fit but also with a random balanced hand and no obvious fit. Similarly:

1♠ - 2♣ - 2♦:

2♥ = just relay, asking about opener's pattern
2♠ = 3+♠ as normal

Yes, you are not going to be able to get both openers shape and control bidding of hand in before you get to 4H, agree.

One thought, worry less about openers shape. Now you can focus on openers control bidding.

With only one or zero keycards, assuming Hearts are trump, opener rebids 4H over 3H.
With 2+, start to control bid, A or K or stiff or void. To be clear opener cannot show a stiff or void in clubs, on this specific auction.
