The bidding starts 1m-(1S)-X-(2S). For me X simply replaces the uncontested 1H response. A tad stronger maybe because responder does not need to keep the bidding open. If you put more in that double, it’s even more difficult. I would like a structure that can also be applied after 1m-(p)-1H-(2S). Please help me out.

X = 16+-19 bal or nearly with fewer than four hearts
2NT = weak or strong, if weak then m rebid (or C rebid if m = D); responder's 3C is limited to 11 when m=D, less when m=C
3m = nat, NF, extras
3om = nat, extras (NF if D, 1RF if C)
3H = heart raise, limited to bad 16
delayed 3H = heart raise, 16+-18
delayed 3S = splinter raise of hearts
immediate 3S = stopper ask, often with running m
immediate 3NT = to play, based on running minor and a stopper
delayed 3NT = to play, 19+ with a stopper
4H = to play, some shape
delayed 4H = 18+-19 balanced with four hearts

Matchpoints, NV against V opponents. Dealer holds:

Opponents pass throughout. How would you bid these hands after 1D-2D-2NT?

What system are you playing?

In KS, the response is not 2D, and the rebid is not 2NT.

The response certainly is 2D.  The rebid is arguably 2S or 2N.  

One possible auction is 1D-2D-2N-3S-4D (interest but no C control)-4H (kickback)-, which gets you to 6D.  Or responder bids 5C over 4D and maybe you stop in 5D.

Playing KS. Using https://www.bridgeworld.com/pages/readingroom/kaplansheinwoldupdated.html, B-1 indicates that 2D is the right response. B-22 suggests that both 2NT and 2S are candidate bids.

1D 2D
2NT     ?

I'm not sure why you think the response is not 2D, nor what you think it
should be. You are right that the rebid is not 2NT, which shows either
a 4=4=3=2 hand or a crappy 15 count.

"Likely 3-card m (could be balanced 15 with 4 cards, but poor for suit play)" No resemblance to opener's hand.

It's a 15 count with only one keycard and 10 of the 15 points in short suits.  That's not wonderful for 5m, and you aren't playing a spade Moyse with two deuces to the K9.  So, it's reasonable to call it bad for suit play.

In strong notrump systems, if there is a consensus about single raise of minor forcing (which I doubt), it is first to explore whether notrump is playable.

In KS, one first explores whether the fit is slam-suitable.

There is plenty of room to stop in 3NT or 4NT.

It's bad enough that if you reversed the majors,  I might open 1N in an odd numbered seat...

I might actually rebid 2S at the table.   I just wouldn't call 2N "not KS".

Sorry. I had the dealer and responder switched.

Now that I have the positions straight: the 2NT rebid would be clear without the diamond ten. With it, I would hate to de-emphasize the suit.

Richard, you (likely without malice aforethought) highjacked my thread.

I don‘t like to include 4crd raises in GB2N. Opener must be able to double 4S with the good 2N. Responder has a tough decision if there still can be a good H-fit. If X is t/o and not limited to a balanced hand, 3om can show the good H-raise.
