Challenge v BillyFung2
BilllyFung2 wrapped up a pedestrian Moysian 4♥, overcoming the 5-1 trump break.
GIB and I punted 6♦. Down one, on a trump lead. I win the challenge, if I fluke this contract but got nowhere near the successful line.
I've simplified the deal, weakening the N-S hands, to bring into stark relief, a remarkable line to make this precarious contract, at double-dummy, on any lead.
Can you see it?

Ruff a spade, club to the Q pick the trumps up and W comes down to 4 hearts, club A and a spade, when you play the last trump he has to divest himself of the spade, meaning you can duck a club to his bare A and score the K and 3 hearts.

Spoiler

Win the trump lead with the king, deep diamond finesse. Club to the queen (West must duck or you have 12 tricks). Spade to the queen, ruff a spade, diamond hook. Now cashing your last diamond and the ♠A puts West in a squeeze without the count (having to find a discard from ♥QTxx ♣Ax)

CyberYeti and Manudude03 cracked it.
Win ♦A, finesse ♦8, lead a ♣ to ♣Q, finesse ♠Q, ruff a ♠, finesse ♦T. and cash ♦A, drawing East's last trump.
Now, finesse ♥J and cash ♥A, revealing the ♥ split.
This inspired play establishes the distribution of defenders' hands, which allows declarer to continue double-dummy (or claim).
West has been triple squeezed out of his ♠s.
Finally, in this 4 card ending, ♠A operates a positional-squeeze on West in the round suits, without the count.
Dummy keeps the suit that West abandons and declarer plays it.
