     Bridge players are no different than anyone else.  They each
have their own idea of what is right in any given situation. 
Here, East decided to bypass a perfectly good four card heart
suit and respond one no trump after partner had opened a diamond. 
South should bid two spades in either case, but here it ended the
auction.
     The hand came up at a local duplicate bridge game and Gail
Joelson of University Heights was declarer.  The opening lead was
the queen of diamonds.  Joelson could count five spade tricks,
two diamonds and a club for a total of eight.  Her contract was
safe so it was time to play for over tricks.  Remember, in the
game of duplicate bridge, this hand has just as much importance
as a doubled grand slam.  The top score that could be achieved on
this hand was eight match points, no matter what the contract
was.  What better time to look for over tricks than when your
contract is ice cold?
     The opening lead was won in the South hand with the king.  A
small spade was led to the ace.  The four of spades was led to
the jack, which held.  The king of spades captured the queen and
completed the task of drawing trump.
     With one over trick assured, Joelson saw no harm in
attempting to win a tenth trick.  This would mean that one of her
losers would have to "disappear".  The spade length in the South
hand indicated that there might be squeeze possibilities.  With
nothing to lose, Joelson led a small club and when West played
the six she called for the nine from dummy. East won the king and
returned a small heart to West who won the queen and the ace.
     The defense had taken three tricks at this point.  West
shifted to the jack of diamonds.  Joelson won the ace and then
ruffed a small diamond.  She played the ten of trump and came to
this three card ending:

     South is on lead and plays the nine of spades.  West is
finished.  No matter what is discarded, the last two tricks will
be won by declarer.  How will you know what to discard from
dummy?  After all, you cannot see West's final three cards.  The
only card you have to be aware of is the ten of diamonds.  You
know that West has it since East showed out on the third round of
diamonds.  Therefore, if West discards a club when you play the
last spade, you must pitch the eight of diamonds.  It cannot be a
winner.  Either the ten of clubs will stand up as the tenth
trick, or it won't.
     As it turns out, the ten of clubs is the tenth trick and
Joelson's careful play earned her a tie for top on the hand.
