♣ Q 3
  South is to play 3NT. West leads the ♠2.

Winners:   ♠ = 2    = 0    = 2   ♣ = 1   Total = 5

Obviously you need to establish 4 winners and by driving out the A you can manage that handily. The problem is that dummy has only one sure entry, (the ♠A), and the defenders may be good enough to hold up their A twice.

To assure the contract you should win the first trick in your hand with the ♠K. Then play Q, J overtaking with dummy's K so you can continue establishing the suit while you still have that ♠ entry.
