Q 3      
Contract is spades.  South to lead.  Win 4 tricks.
Solution:  Play the ace of diamonds discarding the ace of clubs from the north hand!  Declarer then plays a second diamond and ruffs it.  Now the two of clubs from North and East can win his king but is then forced to play another club, allowing South to win the last two tricks with the club queen and a small diamond.  Alternatively East can duck the club at trick three but will still give up tricks to the queen of clubs and South's long diamond.
