     Opening Lead: CK
     It was late at night when this hand came up at the weekly
rubber bridge game.  Everyone was tired and the North-South pair
were way behind in the rubber.  Had West made the pedestrian lead
of the three of hearts there would be no story to tell.  While
declarer can set up the spade suit and come to ten tricks, he
can't do this unless he can see all of the cards.  The defense
should always score four tricks before declarer makes his game.
     West, however, led the king of clubs!  South won the ace and
played two rounds of hearts, ending in hand.  A small spade was
led to the king and ace.  East returned a club, ducked by
declarer and ruffed by West.  West continued with the ace of
diamonds and a diamond to the king in dummy.  Declarer still had
a spade to lose for down one.
     The winning line of play is to draw three rounds of trump
ending in the South hand and then play a spade to the king. East
can do no better that to win the ace and return a diamond.  West
wins the eight plays a diamond to the king.  At this point
declarer's problem is a lack of entries to the board.  He still
needs to establish a long spade trick to allow him to discard a
club loser.  The correct play is a low spade to the eight.  It
wins in every situation except when East started with four spades
to the A-J-10.  Unfortunately, declarer did not find the winning
play until the ride home.
