     (1).  Forcing to game.
     (2).  A real diamond suit.
     Fritz Babsch of Austria reported this hand in the June
Bulletin of the International Bridge Press Association.  It
occurred in a team tournament in Aldrans.
     In the open room, North's double of seven clubs requested
that partner make an unusual lead.  South did not have many
choices and decided that the king of diamonds was the best he
could do.  Unfortunately for the defense, declarer was also void
in diamonds and the doubled grand slam was worth 1630 points.
     In the closed room, North passed and East opened the bidding
with two diamonds which was a part of the system that this pair
was playing and only said that East had a game forcing hand.  The
bid did not specify any suit.  South passed to wait and see what
would happen next.  West showed a diamond suit, East showed a
heart suit, and South came out of hiding to bid four spades.  A
couple of cue bids later, South found himself to be the declarer
in seven spades, vulnerable, doubled, and redoubled.
     The opening lead was the five of hearts.  Declarer ruffed,
drew the outstanding trump, ruffed the four of diamonds in dummy,
noted that East had no diamonds, returned to hand with a ruff and
took ruffing finesses through West.  The score was 2940 for the
North-South pair.
     The team total was 4570 on this hand alone which was a 24
IMP (International Match Point) swing.  Despite this monster
result, it was only one match and at the end of the event this
team was only able to claim second place.
