          Opening lead: DQ
  In a Bracket One team event, I felt that the hand I held as South was too
strong for a simple overcall.  I made a take-out double and West redoubled 
to show a good hand.  This came back to me and I bid one spade. After two 
passes, East bid two no trump.  I bid my second suit, clubs.  West doubled
and partner took me back to three spades.  East doubled and West led the 
queen of diamonds.
  The jack of diamonds won the second trick and the ace of hearts won the
third trick.  Another heart was trumped with the seven of spades.  The king
of spades drove out the ace.  East returned a small club which went around 
to the queen.  I led dummy's last spade, drew trumps and claimed for plus
730.
  This was always going to be a good score but when our teammates came back 
to the table we found that they had played the hand in the East-West direction
at three no trump, making an overtrick.  The combination of a vulnerable game
in each direction was worth 16 imps (International Match Points).
