  You were expecting to see all four hands, not just North/South again.
The reason you are seeing it like this is that you must do some deducing first.

You saw the bidding and you know that West started with the A and East started with the K.

Before you can make a good Plan you need to figure out where the ♠A, K and ♣K are located.

  The three unaccounted for honors have a value of 10 points and every one of them must be in East's hand. With the K he still needs those points to have enough strength to open the bidding. So you can forget about either finesse working.

Now on with the plan. East/West took the first two tricks and then played a third which you won, discarding the 2 from dummy.

  You need to pull trumps so you play your ♠K. East wins with his ♠A and returns the ♠3 to your ♠Q.**

This pulls all the trumps and also serves to rectify the count for your upcoming squeeze.

**By the way, notice that if East had played any other way he would have handed you the contract.

A Q 10 7
♣ A J 4
  You plan to squeeze East in s and ♣s. But if you start running your trumps now you will have a problem with dummy's discards. You will come down to the A Q and the ♣ A J and will have to discard one of them BEFORE East has to discard.

So dummy's Q cannot be one of the Threat cards. Instead you must make the J in YOUR hand a Threat. You do that by playing the A immediately, a Vienna Coup.

  Now that you have your Threats properly positioned you can get on with the squeeze.

Overtake dummy's ♠10 and run three more ♠s.

Discard all three s from dummy.

East will discard his 2 s, the 9 and the ♣6.

  And now the moment you have been waiting for all these 20 Deals.

Play your ♠2 and discard dummy's ♣4.

Poor East will squirm and try to figure out which discard is best because he doesn't actually KNOW what two cards you have left.

But you aren't squirming because you know that whichever card he throws it will give you your contract.
