2♥ - 2NT?
What does this 2NT mean in your partnerships?

This is actually true in two partnerships, but in different ways. In one, it is explicitly a bad raise. In the other it's just a competitive way to get to the 3-level, but nothing else but a club raise would make sense given the auction so far.

You can have your cake and eat it too by playing 2N as NF with either a bad club raise or 18-20 BAL.
"NF lebensohl" (my name) is useful in other situations, too, e.g.
1♣-(2♠)-P; 2N = a) MIN 6+ C b) 18-19 BAL,
and is one reason for not playing Mexican 2♦ in a standard system.

I think that with a balanced 18-20 it is ok to double again. Or maybe, if a 1NT overcall includes some 18 counts and the free 2♣ bid shows some (5)6 points, you can just force to game.

I will have to ask my partners! lol
Options at this point are
1 dbl Surely a penalty dbl we have advertised a heart suit
2 2♠ a good hand with a spade suit, too good for an initial 1♠ overcall
3 3♣ support for clubs nothing exciting
That leaves
2N, 3♦, 3♥, 3♠ and 3N
3N looks like 19+ balanced, as my 1N overcall is 15 -18, with good red suit stoppers
3♦ looks like 19+ balanced, no ♦ stopper
3♥ looks like 19+ balanced, no ♥ stopper
3♠ GF I really like ♠
2N could then be "partner are you better than minimum" if not bid 3♣. If I then bid on we are GF. If partner bids something else we are GF
Effectively, this is reversing the suggestion that 2N is a competitive raise and 3C is forward going

Using it as some Lebensohl-style bid to denote good or bad club support by the doubler just seems pointless to me (just my opinion).
As Helene_t indicates, that the free bid of 2♣ in this competitive auction is so limited in strength that the doubler should know where the auction is heading, and should bid accordingly.

I may be wrong but I think Helene meant that the minimum value of 2♣ was 6 hcp (5 at a push) I think there is a fair amount of upside before partner can do something more constructive like 2♦
After all with a 4414 hand the doubler can have only 13hcp
2N to play looks like trying to land on a sixpence (or dime) (or cent)

1. penalty for hearts (takeout for diamonds)
2. big, balanced with good hearts
3. big, balanced with poor hearts
Obviously if we want to take action with #1 then that has to be with a double. That would lead me to choosing #3 for 2NT. #2 then becomes the "unbiddable" type and we therefore have to choose between X and 2NT depending on the strength of our hearts and suitability for penalising. That would make 2NT neither completely natural nor completely artificial but a bit of both. If we instead were to use 3NT for that then there is no room left to check back for the quality of the stopper, which would seem to be a fatal flaw.

You don't think there is some value in being able to show a hand that just wants to play 3C as well as a hand that wants to invite partner to bid on with a 10 count and pass with a 6 count? That's exactly what playing some sort of good/bad gains you here.
The thing is that adding any convention means you have to give up something. Often what you give up isn't that important (e.g. the ability to play 2C opposite a 1NT opener when you start playing Stayman), but good/bad 2NT means you can no longer bid 2NT naturally. Sometimes, and this is one of those auctions, the natural meaning is valuable. So you have a choice when you design your system. You can either make the rules simple to remember and straightforward to apply, or you can assign the optimal meaning in all situations.
If you try and find the best meaning for 2NT in all competitive situations, you will wind up with something that you can't remember. Especially because then someone will come along and point out (correctly) that in many cases the weak hand should be bidding directly at the three-level, while the good hands go through 2NT. But not always. And now you have a whole new thing to remember. So we've made some trade-offs and come up with rules we can remember and apply in a broad range of situations.
There are some times when we think it's not the best meaning for the auction, but we accept those. It's not that we've thought about this precise auction, but that our general rules lead this one to be a bad raise to 3C. I actually think having the two ways to get to 3C is good here, but it's probably not a huge difference one way or the other.

It seems better for 2NT to be the weak raise, because when doubler actually has extras you might want to play 3NT, and it will be important to play it from the right side (often, but not always, advancer's side).

It is therefore forcing. Partner is asked to choose 3C or 3NT.

If 3C is the good raise you can still arrange it so either hand can play 3NT. If 2NT is the good raise, you're locked into the doubler declaring. Often but not always the best person to declare.
