Strong NT system question

1C/1D (whichever you open)-(2H)-2S-p
What is the correct bid here?
The reason I'm asking is because partner and I are thinking of switching from weak NT to strong, and it'd be a good idea to get niggles like this sorted out before staring to play it I've seen some strong club systems use the cuebid (3H) as a "help me please partner" bid in situations like this, but that could get you awfully high when partner, holding an invitational hand, still has no idea whether you have enough for game or not. Is some sort of artificial 2NT needed?

You can give up the natural 2N for a good/bad 2N, but there are times when you want to play 2N, and you also give up the possibility of having the natural auction 1D-(2H)-2S-(P)-2N-(P)-3N, which leaks a lot less information than any other auction to 3N.

1♦ followed by 3♣ is exactly the reason why most open 1♦ with this hand. Otherwise you just have to swallow a 2nt rebid without a stopper.

don't forget that when rho doesn't raise, it often means partner's got values there.

Jxx, T9x or similar in hearts would make me lean towards 2NT.
HH and some Hx in spade you can make a simple raise to 3S.
Chunky holdings in both minors might try 3C.
And with a maximum I might stretch with 3H (although this depends a bit on partnership agreements).

It has been observed by others that T-Walsh and unbalanced diamond openers all loose out on preemption over 1C openings, which tends to get overloaded.
If you believe in interference against strong club system, you should do likewise against those.

This is the main argument people make for oepning 1♦ with 4-4 in the minors.
If you open 1♣ you are forced to bid 2NT, relying on that RHO has not raised and preemptor rarely has a solid suit.
This scenario is essentially an advertisement for negative free bids at the two level.
A negative free bid is not weak but constructive with a good suit, but it is not forcing.
Nine times out of ten people make the same suit bid with the same hand whether they play 2♠ forcing here or not.
Only the negative free bidders are in a much more comfortable position, while others get too high.
The forcing 2♠ frequently hold a hand where they have to choose between overbidding (forcing their partner) or getting stolen blind, if they pass or negative double.
When responder has a truly game forcing hand playing negative double he either jumps to 3♠ which is strong with a good six card suit or doubles and bids spades later, which shows a game forcing hand with a 5 card suit or six mediocre spades.
The scenario that you might get preempted (LHO jump raises preemptor to a high level) when responder has a game forcing hand almost never happens in practice.

However, I am in three minds as to how to handle WJOs here :
(1) Natural and forcing is easy, together with a values (penalty orientated) double. However, over a non-jump overcall I like 2♠ to be non-forcing, and if they have a normal WJO in hearts, it is quite likely responder may have a similar hand in spades, and it is a shame to lose that.
(2) A negative free bid (NFB) that is non-forcing misses out when responder wishes to double them for penalty. Double for me is a hand with some values and hearts, no long suit, not good enough for 3NT (or prefer to double), where the knowledge that opener also has a couple of hearts means that you do not expect their contract to make. This is not uncommon. (If opener does not have 2+ hearts, he will have 6 clubs and take the double out to 3♣.) If a "GF with 5 spades" hand is forced to double when playing NFB then you miss out on this.
(3) In some other circumstances I play transfers over a WJO, starting with double, but not after a strong NT, and as we open 1♣ with a weak NT hand, it should not apply here for the same penalty reason.
Thoughts, anyone? I am leaning towards NFB with a forcing 2NT response. A GF hand with a 6 card spade suit can make a forcing 3♠ bid, and a 5 card (maybe 4 card?) spade suit can start 2NT and see how it develops. The "natural 2NT hand" will double for penalty. Is this workable? Any idea of how bidding should go after the forcing 2NT?

Which leads to the argument for combining the unbalanced diamond with a strong club so as to combine the disadvantages together.

Of course there are other mainly artificial possibilities.
But playing transfers makes it difficult to stop in 2♠, when responder has say 5 spades and opener two or three unless transfers start with double, in which case I do not know what you do with 4144,

May I ask you to elaborate a little?
2♠ = to play
2NT = transfer to clubs, to play or better
3♣ = transfer to diamonds, to play or better
3♦ = transfer to spades, invitational or better
3♠ = 6 card GF
?
If this is it, I could happily take this as a base. It meets my needs, if I extend the 2NT bid to alternatively mean other things, such as the 4 spades takeout, which can then be shown by using the possible rebids over 3♦.

We basically just treat 1♣-(2♥) exactly the same as 1NT-(2♥), which in our case means
2NT = Clubs INV+ or signoff in diamonds or "slow" 3NT bid (with stopper)
3♣ = Diamonds INV+
3♦ = Spades INV+
3♥ = Short in hearts, typically 3145
3♠ = Would show the minors over a 1NT opening, here exceptionally it is a transfer to 3NT, typically showing an antipositional stopper such as Axx or JT9x.
3NT = "fast" 3NT bid (values but no stopper)
Analogously over 1♣-(2♠):
2NT = Clubs INV+ or signoff in diamonds or hearts or "slow" 3NT
3♣ = Diamonds INV+
3♦ = Hearts INV+
3♥ = Transfer to 3NT
3♠ = Short in spades
3NT = "fast" 3NT
