You have 7 points so you know your side does not have a game.
You also have no reason to think there is any better contract than 1NT.
So you pass.

North would play 1NT. To make life more convenient the hands will be rotated so that South becomes declarer.

Click ROTATE .

  South plays 1NT. West leads the Q.

Winners: ♠ 1 : 2 : 1 : ♣ 1 : Total = 5

You need two more winners. Even if the s split 3-2 you can get only one more from that suit. So clearly you must use the ♠ suit. Since you have only one entry to dummy you must save it until the right time.

Win the first trick with the K. Then play ♠A followed by ♠2. Continue playing ♠s until the ♠K is forced out. Win whatever they play next and play your other winners. You cannot be stopped from taking 7 tricks.

  Imagine what would have happened if you had taken the first trick with dummy's A.

What would you try next? A ♠ finesse? Whether West took his ♠K right then or later you would go down. You could never reach dummy again.
