The auction looks normal, but there's something to be said for converting 3NT to 4♥. That gains when we need to set up the heart suit in 3NT, and partner has only one entry, and we don't have four losers in 4♥. It loses when either the hearts were already cashing and 4♥ has four losers, or we can make 3NT without using the hearts and the trump losers mean 4♥ goes down.
The lack of spots in the minors makes that last chance less likely than normal. I'm sure I'd have passed at the table, but on this particular hand I think it's better to bid 4♥.
Edit: I wouldn't consider upgrading. The AK doubleton more than counterbalances the positive features.

I like the honour structure, all aces or touching honours so I think that is worth 22, but the AK tight is a minus so for me it's a pretty solid 21.5, I'm relatively happy either way playing 20-21, I would upgrade playing what I play which is good 19-21.
I would pull to 4♥, there is a danger you will never get to some or all of partner's hearts in 3N.

*** Rosenkrantz had upgrades for more than expected controls.
2Nt expects 5 controls; having 8, I'd start 2C.
How can partner envision slam even with DA + K+ K?
He expects we are at 8-9 controls, NOT 12!
Not only would I get to 4H, but I must Q-bid 4C on the way.

I quite like this rule, assuming it only applies after a 2N opening not a 1N opening.
4H was successful on this hand, partner held xxx JT987 A9 JTx, so 4H was massively better. Trumps were 5-1 but it was still worth a swing when four rounds of diamonds stood up.

It's in one of the books of Marshall Miles. Someone mentioned that in the past in one of these forums of BBF if i remember correctly, he was also refering M.M as the source.
"It's only when a mosquito lands on your testicles that you realize there is always a way to solve problems without using violence!"
"Well to be perfectly honest, in my humble opinion, of course without offending anyone who thinks differently from my point of view, but also by looking into this matter in a different perspective and without being condemning of one's view's and by trying to make it objectified, and by considering each and every one's valid opinion, I honestly believe that I completely forgot what I was going to say."

For instance, he doesn't like being used as a human shield when we're being shot at.
I happen to think it's a very noble way to meet one's maker, especially for a guy like him.
Bottom line is we never let that difference of opinion interfere with anything."

great shot at 9 opposite xxxxx in either minor and with
so many controls just plain too good for a mere 2n
(20-21) opener.
If responder had a cruddy 5 card major and enough to
go to 3n they would have used stayman to make sure
they had a 9 card fit before playing in their cruddy suit.
That means thei hearts are reasonable quality and
converting 3n to 4h makes a good deal of sense.
I will admit I do not see any real value in cuebidding
except for the idea this hand is too good for a 2n opener
anyway sigh. I p had slam aspirations surely they would
have at least invited. No sense letting the opps know just
how good your hand is with little to be gained.

OK my D are nice but with 21 HCP I have to have some nice suit.
I have no 5 card suit and AK tight has to be enough of a downgrade to cancel out the other factors. If I upgrade to 2C I will then show 22-24 in many systems and that really scares me as we may get overboard.
As for pulling 3NT I'd like to see a sim and perhaps MP vs IMP is different from the sim results. That being said, I pass and say GLP.

I think no one would be bidding hearts on these two hands as South. I would think the same rules apply to hand in question after the 2NT opening, but of course if partner hitched a long time before bidding 3NT... WELL, that would be a horse of a different color. Of course, should you bid 4♥'s in that case, expect to be ruled against if 4♥ makes.
I am not up to running a simulation today, but I did do a very quick bridgebrowser check for 2NT-P-3D-P-3NT where the 2NT bidder had a 4432 with specifically AK doubleton in hearts and responder was balanced or semi-balanced with exactly five hearts. Passing 3NT was the clear winner at both matchpoints and imps. I did not examine the hands, just average results.. no double dummy play was studied... just how people faired. The sample size was small, 77 deals -- each deal played 16 times (a total of 1136 different auctions). In this study, the scores for 3NT and 4♥ are shown. Of course, other people reached different contracts on the same hands... slams, partscores, even other suits. 3NT was a clear winner, averaging in this LIMITED study +1.46 imps, and 54.2% matchpoints. 4H averaged +0.26 imps and 44.7% matchpoints. The sample size is too small, plus, with no constraints but the auction, a lot of people way overbid either not stopping lower when they should or going too high. In fact, less than 1/2 the auctions ended in either 3NT or 4♥, so it is not clear how useful this is. I did look at 2N-3h-3S-bid game and it followed the same trend and the same preference for 3NT to be right.
