Playing a style of 2/1 where Opener's 2NT Rebid is 12-14 bal or 18-19 bal, obviously the bigger hand bids again.
With a doubleton in Responder's suit, it makes sense for Opener to rebid 4NT quant.

My question is, would 4♣, 4♦ and 4♠ over 3NT in this sequence show three card support for Responder's minor and a slammish 18-19 bal hand?

It seems logical to me playing this 2NT rebid style, but I've never read/talked about it, and I usually play a different structure.

Thanks

I'd argue that opposite 18-19 bal with 5332 shape and no major fit the most likely slam is 6NT even if you have a 5-3 fit in a minor, so I'd probably interpret this as a general cue bid, neither promising nor denying diamond support. Also I think this two-way 2NT is a bit shifty - the bidding is already GF, and now opener needs to introduce artificial bids at the 4-level to show his strength. Normally 2/1 avoids this, bidding slowly with strong hands.

I was taught to respond 2NT as 12-14 and 3NT as 18-19 (17+ over 1M).
Not sure what disadvantages this has compared to a two-way scheme, the advantage of clarity is obvious.

I would have said the advantages of going slow were fairly obvious also - eg what if responder has heart support and was planning to make a delayed raise of 3♥ then start a cuebidding sequence? If the right spot is no-trumps, you can always show your strength later; if not, you get the extra room to find it.

A poll was done on the 3NT bid at BW a couple of years ago - far and away the most popular option (45%) was a 15-17 that wasn't suitable for 1N, with 28% voting for 18-19 options, 12% saying never bid it, and 8% some form of minimum. Many of the voters / commenters who voted for it showing 18-19 said they'd still go the 2NT - 4NT route for suitable 18-19 hands.

My preference that these show shape in a (semi)balanced hands. E.g. if you are 2524, you get a much more defined auction if you first bid 2N and then follow-up with 4C. If you start with 3C, and partner bids 3♥ (which he often has to do on a doubleton), then what next?
4D would show 3-card support.

1♥ 2♦

That looks playable!
The players who use the structure used Opener's Jump-3NT rebid for something else, but this makes a lot of sense.

My preference is:
1♥-2♦:
3NT = 15-17 and ♣ Splinter
4♣ = 18+ ♣ Splinter

1♥ - 2♦
2NT - 3NT:
4♣ = 3 ♦ + ♣ cue bid
4♦ = 2542 18+
4♥ = 3♦, Solid ♥, no ♣ cue
4♠ = 3♦, no ♣ cue bid, no solid ♥

Sir ,to me it sounds a club cue with an honour to three D support and of course 18-19 HCP as per the bidding understandings mentioned.

Seems to me it would show the higher range, with concentration in C with relatively weak S.
