What's your opinion on this one:
1♥-P-2♣-P
3NT-P-4♥ ?
Preference or slam invitation ?

With strong hand bid slow. 2♣ promises a 2nd bid, so there is no reason to jump like an kanguruh. 2NT shows 12-14 OR 18-19. If partner raises to 3NT you can show your 18-19 with a quantitative 4NT.
Playing SAYC 3NT shows 18-19 I guess. 2♣ shows 10+ HCPs. In this range (with 28-31 combined HCP) 3NT is always better than 4♥. So the 4♥ bid is strongly inviting to slam. It is forcing for 1 round at least asking opener to cue or go RKCB.
♠♥♠ BAD bidding may be succesful due to excellent play, but not vice versa. ♦♣♦

I guess the most popular treatment is to play 3 NT as exactly 5332 with 15-17 HCPs.
In this case 4 ♥ is simply to play. Maybe you look at xxx,Axx,x,KQJxxx and think that 4 Heart is safer/gains more tricks. With SI you can make an advanced cuebid.
But when you read throught the convention cards at bbo, you will see that this bid (1 Heart 2 Club 3 NT) has different meaning.
Just from the FD-Files:
It is not defined in Sayc
It is 18-20 without clubs in SEF.
It is 15-17 with 2 clubs in bbo advanced (aka 2/1)
It is not defined in wj2005 (but is is 15-17 5332 here too)
So I would play it as Slam invitation in SEF and to play in the other systems.

What the range for the well-defined 3NT is... now that's another question. Minimum for me.

The most popular approach with 5332 15-16 hcp in NA is arguably to open 1N, so we should scratch that holding from the mix for many players.

Knut: this problem, as posted, is of no real utility.
No-one can tell you what the 4♥ means, not even the player who bid it, unless we are informed as to the meaning of 3N.
If I were playing opposite an unknown partner.. and he threw this at me, both he and I would be guessing. I'd be guessing what he meant. He'd then be guessing what I guessed it meant, and so on. Therefore neither player would know what either bid meant.
Tell me what 3N was intended to show, and I will tell you what 4♥ 'should', imo, be.
BTW, bridge logic tells me that the best use for 3N is natural, too big for a 1N opener.... 5332 with good 17-19 hcp. That automatically makes 4♥ a slam try.. but is it a forcing bid? Just because it shows slam interest need not make it forcing, so even answering the OP question is only half the battle.

FWIW, I would take 3NT in 2/1GF with "frequent" 1NT on a five-bagger as showing a 6322 15-17 count (-ish), without discussion.

And 2♣ followed by 4♥ shows a GF (vs a min 1♥ opener) with 3-card support. Thus 4♥ is a slam try, but NF.

I don't believe you.
I think 3NT shows 5332 and 17-18, because you would open 2NT with 5332 and 19.

It seems there are various ways of interpreting this bidding sequence. The board was played on BBO with the 2♣/4♥ bidder having sayc as profile (nothing more) and the 3NT bidder had a 5-3-3-2 hand with 17 points. I suppose the 3NT bidder tried to adopt to partner's sayc (?) and (mis)interpreted the 4♥ call as preference. Outcome was 7 tricks....
Thanks again for all your insight.

Noting that many non-Americans who say that they play SAYC don't play Jacoby 2NT, I most certainy would interpret this pull to 4♥ as preference if playing with any pickup. PD interested in slam can bid something else.

1H>2C GF /say 12+ C suit may contain 4 cards
3N>Ty but i m 13-14 will try my chance for 3NT with 25-26 HCP by partnership cards; since 2NT still forcing one round and pass not expected i decided to give a shutout bid with any limit 5332. If i had a 4+cards side suit for sure I wld show it. Moreover I dont have 3+ clubs to support yr 4/5 cards clubs.
4H : I got yr message p. Well not today, my distribution unbalanced , why dont u try safer 4H contract with ruff chances. Srry, i cant use any convention (Gerber/RKCB) or bid a new suit to ask a mild slam possibility under such circumstances. My rebid also denies J2N. If I had i wld use directly while i found a good fit to your opening suit.
