This is a www.playbridge.com deal, and not actually played; however, I found it interesting.
You, West, open 3rd seat with 2♣, partner answers 2♦, and you say 2NT. After a checkback Stayman, you end in 3NT.
The defense starts with two rounds of diamonds, South unblocking the king. How do you proceed?
You have 7 high, but the defense will surely cash 3 more diamonds if they get on lead. You can get 2 more in ♥ if the Q drops singleton or via finesse if South has Qx - both unlikely. You can't get a 4th heart via finesse due to the blockage; South is not going to "cover an honor with an honor" seeing the 1085 still in dummy with no other entries. So the best play is to cash ♥AK and hope for the Q to fall - or other chances ....
Both follow low to two rounds of hearts, so you cash a high spade, cross to the ♣K, and take the ♠ finesse.
Pity poor North!
No matter whether South covers or not, North is squeezed in three suits on the 3rd spade. The ♥Q or a club is immediately fatal, so North throws a diamond. But now you just exit in hearts or diamonds. The defenders get 3 diamonds and a heart, but then North must lead away from the J4 up to the A10. A 3-suit strip squeeze!

Note: If South plays an honor when you play a club to the king, and North throws a low heart on the 3rd spade, you can try to drop the QJ doubleton. If on the other hand, North plays a club honor, you're best off taking the club finesse (giving you 5 clubs if it wins, and heavily favored via restricted choice).
That puts North in a rather interesting position if you switch one of North's low clubs with the club Q
