West leads the ♠2, you play dummy's ♠4 and East plays the ♠8.


Winners:   ♠ = 3    = 0    = 2   ♣ = 2   Total = 7

Needing just two more winners it looks straightforward to establish dummy's suit.
Suppose you win the ♠10 and play the 9. If the defenders win this trick you are home free. You win their ♠ return with your ♠A, then continue s to drive out their last stopper while you still have the ♠K as a dummy entry.

This won't work against good defenders, who will hold up on the first trick and win the second. Then when they continue ♠s you won't have another to return to dummy, so while you can use the ♠K as an entry to establish the s you will never get back to use the good ones.

Instead you should win the first trick with your ♠A. Now when you attack s a defensive holdup won't hurt you because you have TWO ♠ entries, the ♠J by a finesse and the ♠K.

  West is almost certain to hold the ♠Q because his ♠2 opening lead promises an honor and the ♠Q is the only one you don't have.

So the ♠ finesse is an odds-on play to get a second dummy entry.
