Guys, responder is inviting slam opposite an (assumed) minimum opener. I agree with all that Josh said, except I like 5♥ better than 4N - asking for good trumps seems about what we want to know about.
I also like 5
♥, but I have a problem with it: on competitive auctions I play 5
♥ asking for a control in opponent's suit.
IMO this is not to be considered a competitive auction, but I wouldn't risk partner thinking the other way.
That's why I like 4
♠, partner might bid 4NT just for free, and we will show 3 key cards, wich in fact, its all we have. (not true on the actual hand since partner has a void).
On the other hand, Frances is right that 4NT is our only way to reach 7 with confidence. But I would not assume partner has 7 hearts, IMO he could have only AKQ10xx, and that's not a grand I wanna play.
After 4
♠ -5
♣ we might even propse 6
♣ wich can be great if partner has
