Winners:   ♠ = 0    = 2    = 1   ♣ = 3   Total = 6

You only need one more winner and you have several possibilities. The finesse might work, or the ♣s might split 3-3. But you need to consider the defenders winners also. They have already scored 2 tricks and will get 2 more as soon as they gain the lead. (The spot cards told you that West has a 5-card suit.) Plus they have the 2 top ♠s which they can take whenever they like. So if your play sets up just one more trick for them you will go down.

No, you must establish ♠s, the suit where they have 2 winners anyway. So you play a ♠ which West wins. He takes his 2 s but you are now home free. When you gain the lead again you will get your ♠ winner established and only lose 2 ♠s and 4 s.
