Contract is no trump.  South to lead.  Win 4 tricks.
Solution:  Start by playing the ace of spades.  West cannot discard a club on this trick or all three clubs in the north hand become good, so West must discard his final heart or diamond.  Regardless of which of these cards West discards on the first trick, Declarer discards the heart 6 from the north hand.  Declarer now plays the 2 of clubs.  West must play the seven or eight, if he plays the four Declarer wins the trick with the six and cashes the other high clubs.  Assuming West plays the seven or eight, Declarer wins the trick with the nine and plays the eight of hearts.  If West kept the nine of hearts  on the first trick then East can duck this trick but then West is endplayed to lead into Noth's club tenace.  If East wins this trick with the ace then he is endplayed, he must lead from his five and three of hearts into South's seven and four.
