Neither side vulnerable.  
North deals.

     After a strength showing reverse by North, South elected to
rebid his spade suit instead of bidding three clubs.  Four no
trump was Roman Key Card (RKC) Blackwood.  The five heart
response showed two key cards and denied the queen of spades. 
South wisely decide to sign off at six spades.
     It would appear that this slam was doomed as a result of the
bad break in both spades and clubs.  While a small spade is
probably the best opening lead on this hand, West tried to be
tricky and led the ten of clubs!  My advice here is to not be
tricky too often.
     Dummy's jack won the first trick and a spade was led.  South
thought carefully when the queen appeared on his right.  He won
this trick with the ace of spades and decided that if East had
started with the doubleton queen-jack of spades there would be no
problem with the hand.  Accordingly, he concentrated on finding a
way to make the hand if the queen was singleton.
     Declarer cashed the ace of clubs, noting the fall of the
king.  He finessed the heart queen successfully, cashed the heart
ace and ruffed a heart.  He then cashed three top diamonds and
ruffed another heart.  As he had hoped, West was reduced to three
trumps, the jack, nine and four, while declarer had the king-ten
of spades and the queen of clubs.  Having not yet lost a trick,
the queen of clubs was tabled.  West had no choice but to ruff
and concede the last two tricks to declarer.  This was a case
where declarer had to decide what distribution would allow him to
reach the desired end position, and then play for it.  A skillful
performance with a just reward.
