        West leads the 
        S6, won 
        in dummy who then cashes the HK.  When West shows out, declarer plays 
        dummy's DA and ruffs a Diamond with 
        H4 -- this places South with the 
        same number of trumps as East (both four left).  
        If Spades break 3-3, 
        declarer needs 5 more tricks after HK and ruff.  Ruffing 2 
        more Diamonds in dummy and 2 finesses are required, but how?  
        Playing the fourth dummy Spade provides the answer -- if East ruffs, 
        South overruffs.
