Declarer can also use the Rule of Eleven.
11 - 7 = 4. There are 4 cards that can beat the 7 in the North, East and South hands. Since you are looking at all 4 of them, you know that East has none. So you play the ♠2 from dummy and win the first trick with your ♠8. Later you take two finesses in ♠. Only by winning 4 ♠ tricks can you make this contract.
