To get to 7 hearts in a natural system, you need to open S hand (which is not so out: 11 HCP, with 2 As and a 5-card suit). Otherwise you will have difficulties in telling N that:
- you have a max for a passed hand
- you have a fit in hearts
- you have a diamond suit
OTOH, you need diamonds 3-2 for a grand (plus a few cases with a fav 4-1). The grand should be around 73-74%, which is not bad at all, but maybe not good enough.
The best solution to get there is not playing Drury
If it goes P-1♥-2♦ N should be much more active,

It also helps if you have a more sensible response method to Drury.
1H-2C
2D* *I'm interested. Relay me back to the major and I'll tell you why.
2N* *I'm interested in slam opposite a limit raise.
With this approach, the acution can be:
1H-2C
2N-3H* *Excellent hearts
3S-4D
5D-5H
6D-7D
7H.
However, I would have opened 2N like Justin and had no chance - would feel fortunate to get to 6.

I would have passed as South, and I would
not have reached 7H.

But even if South opens, I think it would be hard to reach 7♥.

Unless the methods you use can find out about the 5th diamond, I think it's more reasonable to settle for the small slam.
BTW, I'd open south's hand.

Agree !
I would have played 6♥ after a 2NT opening and a puppet like sequence.

Is 2NT really a GF opposite a passed hand pard ?
I have always played such kind of sequence as invitational, nonforcing, say a good 13/14 hand.

Yes. To bid 7 without knowing of the 5th diamond is a bit of a shot.
Some shots are worth taking, though.

Indeed, but playing the odds is generally the best way to reduce losses in the long run ( including losing partners LOL)

pass---1♥
2♣*A---2♦ *Reverse Drury
3♦----4♣
4♦----4NT
5♠A----5NT
6♦----7♥
Since south passed, so it's ok bidding 6D showing extra length.

yes, it's good to have such methods, eh? in the relay precision from gerben's site (assuming south passes)
p : 1c
2d : 2h
3d : 3h (3352 : control ask)
4c : 4d (4 : spiral scan)
etc
but i agree with gerben that missing the grand shouldn't cause a p'ship to fall apart

It doesn't seem that complicated to show ♥AQ,♦A and 5 ♦ after a drury sequence, is it?

Help

pass--1♥
2♣A--3♣
3♦----3♠
4♥----4NT
5♠A--5NT
6♥----pass
7♥ took chance of 60%+, would you bid 7? and how?
BTW, do you agree with south's initial pass?
