Contract is hearts.  South to lead.  Win 3 tricks.
Solution:  Start by winning your 6 with the A and then returning the ♣4.  Ruff this with your last trump and play the ♠8 (this is very important it cannot be the ♠5).  Everyone is down to just spades and you need only one more trick.  If West wins the first spade trick then your ♠K is guaranteed to take a trick so assume West plays the ♠6 in an attempt to not win the trick.  You now play North's ♠2 forcing East to win with the ♠Q or ♠J (now you see why it was important to play the ♠8 and not the ♠5 and it is also important that even if West covers the ♠8 with the ♠9 you still play low from North).  If East returns the ♠Q or ♠J (whichever one they kept) you cover with the ♠K, if East returns the ♠7 you play low.  Either way West will need to win this trick with the ♠A (the first scenario he obviously needs to cover the ♠K, in the second scenario if West doesn't play the ♠A then North will win the ♠10).  Now the final trick will be won by either North's ♠10 or South's ♠K depending on which of the above scenarios takes place.
