As I understand it, "bog-standard" 2/1 with 15-17 NT has 1x-2y-2NT showing 12-14 or 18-21 (though I suspect most would open 2NT with 20-21). 1x-2y-3NT would show 15-17.

Question 1: say you adjust your NT range to 14-16. Do you also adjust these rebids to show 11-13/17+ and 14-16 accordingly? Or would you be worried that that 17 is not enough to "make a move" after 1x-2y-2NT-3NT?

Question 2: say you agree to systematically open 1NT with 5-card majors. Do you keep the 3NT rebid for the "I judged to open 1M anyway" hands or is there some more useful meaning?

On a related note, if you are playing 1♦-2♣ as game forcing, what would 1♦-2♣-3NT show?

I suggest the following:

1. Keep the 2NT rebid as 12-13 or 17-19 and the 3NT rebid as 14-16.

2. You can either do
- 2NT rebid as 12-13 and 3NT as 17-19
- 2NT rebid as 12-13 or 17-19 and 3NT as some 17-19 as well, but with a 6322.

3. 1D-2C-2/3N can be defined as in case 2.

AFAIK 1M-2y-2NT shows 18-19. With minimums you rebid 2M (which doesn't promisse a 6 card). If you open 1M with 15-17 balanced as well, then you might want to split up the ranges differently (I prefer 11-15 and 16+).

If you prefer a 2-way 2NT rebid, then I'd adjust the range.

You could use it to describe your hand very well. For example, 18-19HCP, 5M332 with doubleton in partner's suit.

I prefer this to show 18-19HCP with exactly 3♦s (so 4=4=3=2 exactly). Again, a picture bid.

2NT.

While we also use the 2NT rebid to show exactly 4=4=3=2 (both majors), we believe it should be the split range of 12-14 or 18-19. This allows us to establish a major suit fit at the three-level if there is one and, then use serious 3NT to show the 18-19 hand after responder has revealed the major suit fit.

This leaves, by inference, the 3NT rebid instead of 2NT as a different picture bid: exactly 3-3-5-2 with 18-19 (an exception to always rebidding 2D with 5).

1M - 2x - 3N is such a nothing bid, that if you want to assign a specialized meaning to it (like a solid suit and quacks outside), I don't think you lose anything by doing so.

We play 14-16 NT with 5 cards major. So for us 2NT is either 11/13 or 17/19.

We also play rebid of 2 major is mostly but not mendatory 6 cards. Opener can rebid with 5 if he believes it is better lie than 2NT bid such as;

after 1♥--2♦

Jx AQJxx KJx xxx

And we definetely prefer not to rebid a major suit with something like Kx QTxxx Kx AJx and bid 2 NT.

After 1♦-2♣ it's nice to have a weak ♣ raise and a strong ♣ raise available, as well as a clear difference between 12-14 and 18-19 balanced. Therefor I prefer a little artificiality:
2♦ = 5+♦ any strength (min if 6+♦)
2♥ = strong NT with 4+♦ or strong ♣ raise
...2♠ = relay
......2NT = 18-19 bal, 4+♦
......3♣ = strong ♣ raise
2♠ = 4=4=4=1 exactly, any strength
2NT = weak NT
3♣ = weak raise
3♦ = extra's with 6+♦
3M = splinter with ♣ support
3NT = 18-19 bal, <4♦ (so 4=4=3=2)
This way responder also knows for sure if there's a ♦ fit or not when he has 5+♣-4♦, and there's no ambiguity about NT range.

You could also play around with this a bit and change 3NT to 3=3=5=2 (using the strong 2NT with 3-4♦, responder can bid 3♦ and opener rebids 3NT with 4=4=3=2).
