When the fraud was detected Hoogli withdrew before the event started.

Jack was written by Hans Kuijf from the Netherlands. He started programming Jack in
2000 with one goal in mind: to create the best computer bridge program in the world, both
in bidding/play and in features.

Jack participated in ACBL Computer Bridge World Championships where it reached
the semifinals at its debut in 2000 (3rd). After another hard years work
Jack won the title in 2001 and successfully defended it until 2005

After that the program was used to practice the new software technologies Job
encountered as a software developer. Between 2004 and 2007 he took the program
to a higher level adding a double-dummy solver. How high that level actual is
will have to show at the 2007 World Championship.

started the program as a pure bidding program, which he wrote for fun. Then the
program was laid on ice between 1997 and 2001 when he was busy with his newborn
twin daughters. Starting 2001 the play part was added to the program to be
put to the test against the other bridge programs for the first time in 2006.
Shark Bridge made its debut at the 2006 ACBL Computer Bridge World Championships.
