  With 12 obvious tricks your first thought should be that perhaps the ♠s will split 3-3.

Then, your second thought should be that dummy's J is a Threat against West's Q, so if it is West who holds 4 ♠s you will be able to squeeze him.

Since the contract is 7NT you take the first trick with the A.

  With one trick in the bag you should test s next. When you play the A East discards a ♠.

You continue with the Q and K, East discarding a and a ♣.

  Since East has shown up with a void he has become the odds-on favorite to hold the ♠ Guard. His ♠ discard makes it very likely that he started with 5 ♠s.

To find out for sure you play ♠A, then ♠Q. Sure enough West discards a on the second round.

  You can't squeeze West in s and ♠s because he doesn't hold the ♠ Guard, East does.

But now a completely new possibility shows up.
Say to yourself, over and over, "West must guard s, and East must guard ♠s. Nobody can guard ♣s."

You start playing dummy's winners.

  With one more in dummy, things look like this.

When you play the 5 East must keep both ♠s to guard against your ♠7. So he discards the ♣6, hoping partner can stop that suit.

Your ♠7 is now worthless so you throw it.

West has no problem, (yet), he discards the 10.

  It is now time to pressure West.

Play dummy's ♠5 to your ♠K.

West MUST keep his Q so he releases his ♣5.

And you win the last three tricks with ♣K, ♣A, ♣8.

This is called a Double Squeeze.
