Ideally I'd like to agree hearts, show my club control and hear a diamond cue before keycarding right?
If 4♣ would accomplish that then great but wasn't sure - that bid could mean a few different things (splinter maybe?)
I gambled on keycards and we were ok but agreed to look at this particular auction.

So after opener's 2H as above (which does not deny 3 spades) we would like to be able to:
- invite game with 5 spades
- suggest slam with 5 spades
- invite game with 4 hearts (3H surely)
- suggest slam with 4 hearts

We have 3S designated as 6+ spades with slam interest. Supporting opener's minor at the lowest level possible is slam interest with that suit as trump.
Repeating the new minor we have defined as 2 suited invitational but could be artificial I suppose.

Suggestions?

If your style is "never" to rebid 1NT with a singleton in responder's suit, you can agree that after the 2♥ bid
- 2♠ is invitational.
- 2NT is forcing! Think about it: an invitational balanced hand with only four spades would not use NMF.
- 3♣ may be invitational if you play 3♣ on the previous round as weak. But it may be simpler to forget about the weak hands with long clubs, or, alternatively, forget about the invitational hands with long clubs and only four spades. In that case, 3♣ is GF.
- 3♦ obviously forcing
- 3♥ maybe be played as invitational but in that case you need to let 2NT force opener to rebid 3♣ (or 3♦) so that responder has room to set hearts as trumps. In other words, opener can't show 3-card spades support after the 2NT bid. If this becomes too complicated, agree that 3♥ is forcing: responder already showed invitational+ strength, discovering a 4-4 fit in a major should be enough to upgrade to a game force.
- 3♠ forcing with 6+ spades as a forcing hand with five spades would have bid 2NT.

If your style is sometimes to rebid 1NT with a singleton in responder's suit, I suggest these responses to NMF:
2♦: nonmax 1444/1453. Now anything at the 2-level is nonforcing, 3-level forcing.
2♥: 2-3 spades, 4 hearts. Continue as in the other version.
2♠: nonmax with two spades! (Or something terrible like 3343).
2NT: Max with 1444, 1453, 2344 or 2353. Responder can set trumps, or ask with 3♣. Unfortunately there is no way of setting clubs as trumps at the 3-level. Maybe someone can come up with a solution?
3♣: Reasonable hand with 3 spades and less than 4 hearts. This is GF as responder's hand upgrades in light of the spades fit. Responder still has room to set diamonds as trumps.


Maybe not so helpful but honestly: I would suggest diching NMF and play some other checkback structure like xyz or transfer checkbacks. NMF becomes very complicated (and non-standard!) if you want to make it work well. Especially when opener's suit is clubs, it is really inefficient to use 2♦ as the only checkback.

Usually 2H showes 4hearts and a min, with 4 hearts and a max. opener bids 3H.
2H should also deny 3 spades, with 3 spades and 4 hearts opener should show the
spades, if responder has 4 hearts, he also has 5 spades, but sometimes responder
has 5 spades without 4 hearts.
Openers aim is to show the feature, that is most relevant for responder.

From this followes, that most of your req. are no longer relevant
#1 you have no fit
#2 you have no fit
#3 opener rejected the invite
#4 3H

There are more complex version out there 2-way Checkback, which give you
more room, and enable you to find the 44 heart fit in the presence a the 53 spade
fit, but the set of hands, where it does make a real difference is small.

With kind regards

---Note that Responder starts all game forcing auctions with NMF.
---The jumps are all invitational or weak.

Not only reasonable, but easy to remember .

Here, Responder has 2-ways to bid 3H:

1D - 1S
1NT - 2C! ( NMF )
2H - 3H = GF

1C - 1S
1NT - 3H jump = invitational or weak

Marlowe's post almost represents the very early "Hardy" adjunct for NMF continuations (which we still employ some 45 years later). I have thrown in a bit of editing to make it closer; but, for this hand it works.

With the Hardy style (not the OP style), 2H has already shown exactly 2-4-4-3 distribution and only 12 HCP --because of all the inferences. Opener can normally just place the contract after that, so 2S and 3H are both reserved for slam intent.

However, the fact that after a 1D opening and 1NT rebid there is no need for "2-way" and all possible strengths and patterns in Opener are uncovered easily and cheaply after 2C is dependent on a style which many posters will not agree to-----

1) 1C can't be 2 cards
2) (3-2)4-4 opens 1C not 1D.
3) 1NT rebid will not have singleton in responder's suit.
4) Balanced hands with 4 Spades do not bypass after a 1H response.

If you object to any of those four conditions, plain old Hardy NMF will not work for you.
