Both sides vulnerable.  North deals.

          The Bidding://
                  NORTH    EAST    SOUTH    WEST                  
                   1C       1D      1H      Pass
                   2H       3D      4H      Pass
                   Pass    Pass
     After North opens the bidding and then raises hearts, South
will always find his way to four hearts.  West will lead the
eight of diamonds and East will win the king and then the ace.  A
third diamond will be covered by South, trumped by West and
trumped higher in the dummy.
     South should now be working on a way to avoid taking the
spade finesse.  Forget the fact that a spade to the jack will not
work, it is just good bridge to try and improve the odds on
making the contract.
     Since East is likely to have the ace of clubs, South leads a
low club from dummy to the queen.  When that holds, he leads the
five of clubs and plays low from the dummy.  East will probably
win the ten of clubs and exit with a trump (West should make the
same lead if his nine holds).  South draws the outstanding
trumps, ending in dummy, and leads a small club, trumping in
hand.  This play works when East started with two or three clubs
to the ace.
     When the ace does not appear on the third round of clubs
(and West follows with the jack), South has an excellent count on
the hand.  Have you been paying attention?  East started with six
diamonds (West showed out on the third round) and four clubs (you
can safely assume he has the ace from the play).  He also
followed to two rounds of hearts so he has only one spade. 
Accordingly, South cashes the ace of spades and when East's
singleton turns out to be the ten, he finesses West for the queen
and claims ten tricks.
