This hand drove me insane trying to figure out what he could have for 5h. So I played for a distribution, or rather the only distribution, that seemed consistent with the bidding and signals available after trick 1. I placed declarer with x AKQxxxx A Qxxx. This is not a terrible gamble, as you know whatever cards partner has are going to be in the minors, so you hope to find better clubs than diamonds. For the defense unfortunately, Ace of clubs and a club continuation is the only way to beat the hand on this lay-out. It never occured to me that declarer could have xx AKQTxxxx Ax x, yes a 2-8-2-1 hand
No matter how long your hearts, you're looking at two spade losers and chances are you'll find either the Ace of clubs or the King of Diamonds, but probably not both. So with that hand I'd double knowing that partner could have the perfecto.
In defense, having "figured" out the hand, I played the Ace of clubs, partner playing the six from Q876. He apologized for not playing the eight, although honestly the only card that could have stopped me from continuing clubs was the Queen and that would be very hard to find and be wrong when declarer has a doubleton club.
BTW, I absolutely loved partner's 2s bid with KQxxx x QJx Qxxx. Yes, you could pass and hope to balance at the two or three level later, but if it goes 4h on your left, you're out of the auction forever.
I mentioned that partner took a while before playing to the first trick, because it did happen and I'm pretty sure at least some of the players would be calling the director rather than congratulating you on your brilliant defense, had it been right. Partner does have a problem after all, he's worried about how many spades would cash and what his signal might mean. It'd be interesting to send this hand to a reputed director with the 1714 hand for declarer and see how he/she would rule.
