Problem

The Auction:

West has led the ♠5. You can count on four (hopefully one more) tricks in spades, two in hearts and diamonds, three in clubs. You miss the ♥Q and ♦Q, and although a chance of winning a single finesse is 50 %, the probability of two finesses both being successful is only 25%. Besides – you cannot afford to lose a trick as you have just declared 7NT.

How are you going to make it?
