This isn't quite a blind guess, but there's a whole lot of holdings that partner might have when 7♥ is going to have no play.

In particular, its far from clear whether you are going to have an entry into partner's hand

There's a couple cards here that could be crucial to making the Grand.

The first is the King of Spades
The second is the T of Hearts
You can't place either of them with certainty.

That you do know is that partner is pretty much certain that you have three aces and the King of of Hearts.
Opposite a human, the choice to bid 6♥ rather than 6♦ or 6♣ would be telling.
Opposite a robot, its pretty much meaningly.

This might be a good hand for sim

I suspect that I would pass, but I'm far from certain

It would be nice if all grand slam bidding were totally scientific. Here we have more than sufficient evidence to bid 7nt even though we are not CERTAIN it is correct. The 2n bidder surely has more than a meagre 8 hcp to be looking for slam and our 5n response has left them in a quandary about a couple of things. The trump queen and 2 or 4 keycards. We have the max for both and to be honest I would probably have bid 7h over 4n. The dummy will inevitably come down Qxx 42 QJxx AKQx sigh.

It may very well depend on whether it's IMPs or MPs, and, if it's MPs, how good the field is.

With 3♥ showing 5+ hearts, I think even GIB is very unlikely to bid Blackwood with just a 5-2 fit, making an entry in trumps pretty certain.

I would have responded 5♦, as GIB's judgement over 5NT isn't going to be very good, and if GIB follows up with a 5♠ queen ask, we know they have the ♣A, which must make grand worth a shot. Of course, if they don't, we still have a decision to make.

And I don't think the field matters much, as everyone will be opening 2♣ and rebidding 3♥, so will be forced to slam in the same way (just a case of whether they go through 5NT or 5♦), and there will be very little to the play. Well, there may be a few 4♥ preempts, knowing BBO.

But this hand needs to be moved to the robot forum, as with a human this auction is entirely non-existent and of zero interest to non-robot players.

There were some various other openings in the field which included 4♥, 6♥ and 1♥ as well.

The most important thing to learn from that is that the world is full of very very very bad bridge players
