| From the introduction, the bidding in bridge goes 1 Club, 1 Diamond,
1 Heart, 1 Spade, 1 No Trump, 2 Clubs, 2 Diamonds, ..., 7 No Trump; and
bidding by the four players is in clockwise order around the table.
By clue 1, Omar opened the bidding at 1 Heart, followed by Wong bidding
1 Spade.  By clue 3, Ben followed Karpov's bid of 2 Clubs with a bid of
2 Diamonds.  Then Ben is either Wong or was Wong's partner.  If Ben were
Wong and Karpov Omar, by clue 4, Hoyle would have been Omar's partner and
Johnson Ben's; and for Omar to have bid 2 Clubs, Hoyle would have had to
have bid 1 No Trump--no (clue 4).  So Ben was Wong's partner and Karpov
Omar's partner.  By clues 1 and 4,  Omar can't be Hoyle; so Ben is Hoyle
and Omar Johnson.  Ben Hoyle bid 2 Diamonds in his first auction opportunity,
and Omar Johnson passed on his second chance (4).  By clue 2, Carolyn is
Wong and Lisa Karpov; and Carolyn went 2 No Trump in her second chance in
the bidding before the other three players passed.  In sum, the bidding went
as follows:
 
 
-  Omar Johnson, 1H 
 
 -  Carolyn Wong, 1S
 
 -  Lisa Karpov, 2C
 
 -  Ben Hoyle, 2D
 
 -  Omar Johnson, P
 
 -  Carolyn Wong, 2NT
 
 -  Lisa Karpov, P
 
 -  Ben Hoyle, P
 
 -  Omar Johnson, P
