World Computer Bridge Championship Contestants

The first time, we know of, that bridge programs got together to play one another was back in 1989. Since then, several programs have tried to prove best. We tried to gather information regarding all of those programs.

Acolmaster

Acolmaster was written by Paul Jones from the United Kingdom. Paul originally wrote Acolmaster to bid as the 'fourth guy' when playing bridge with friends. Eventually the ability to play was introduced.
It was written for DOS on a 286 and has never been on sale. It is said to work on a Windows system, and can be downloaded from his website!

Acolmaster did not participate in any of the ACBL Computer Bridge World Championships.
In the early years of computer bridge Acolmaster participated in the predecessor of the Computer Bridge World Championships. In those days only 3-4 participants entered a competition of 10-12 boards and Acolmaster was the winner of the first championship ever in 1989.

The program never competed again as the author went travelling soon after the championship. The author continued his career as a software designer for a bank. He was struck by MS and nowadays maintains a website about MS.

Bridge Baron

In 1982 Tom Throop completed the first version of Bridge Baron. In 1958 he had written a first computer bridge program, on a UNIVAC I computer at a US Navy lab in Washington, DC. This program could only finish one round of bidding before running out of memory.

In 1983, Tom Throop published the book Computer Bridge. In 1985, he founded Great Game Products. Nowadays the Bridge Baron team is being formed by employees George Yanakiev / Stephen Smith from the United States.

In the early years of computer bridge Bridge Baron participated in the predecessor of the Computer Bridge World Championships. In those days only 3-4 participants entered a competition of 10-12 boards with Bridge Baron organising some of the events. Bridge Baron finished 4th in 1989, 2nd in 1992 and won the competition in 1990, 1991, 1993 and 1995. The very informal competition of 1994 (when some programmers met in the Throop's residence) was also won by Bridge Baron.

Bridge Baron has participated in ACBL Computer Bridge World Championships from the beginning, but only won the first one in 1997.
Results Bridge Baron: 1997: 1, 1998: 4, 1999: 7, 2000: 5, 2001: 5, no entry in 2002, 2nd in 2003 and 2004, and 5th in 2005 and 2006, 2007: 2, 2008: 6, 2009: 6, 2010: 4.

Eventually Bridge King became Q-Plus.

BridgeMate

BridgeMate was written by Bob Richardson from the United States.
Written with the main objective to provide the user with a tough opponent, Bob allowed for BridgeMate to peek all other hands during play.
As its peeking behaviour wouldn't be a fair skill for a championship BridgeMate participated in the separate bidding contests only that were organized in the ACBL's 1997 and 1998 championships.

Originally developed as BridgeMate during a sailing-trip, the creator later promoted the program's name to Bridge Captain.

Gib participated in ACBL Computer Bridge World Championships where it reached the 4th position at its debut in 1997. Gib won the Championship in 1998 and 1999. Gib didn't participate in 2000 and 2001. In 2002 Gib withdrew with technical problems during the tournament after losing to both Jack and Micro Bridge in the Round Robin.

Grand Slam Bridge

Grand Slam Bridge was written by Electronic Arts from the United States.

Grand Slam Bridge did not participate in any of the ACBL Computer Bridge World Championships.

Website: Grand Slam Bridge has had 2 releases: in 1986 and the last one in 1992. Several sites were found offering -almost- free copies of the program. On the Electronic Arts website no reference to the program was found.

Hoogli

Hoogli turned out to be a copy of Gib that tried to enter the 2001 Championship. When the fraud was detected Hoogli withdrew before the event started.

Jack

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.
The bridge skills of World Champion Berry Westra and Dutch top-player Wim Heemskerk resulted in a program that took the top from the start, yet is still continuously being improved.

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 (World Champion in 2001, 2002, 2003 and 2004). After 4 years of domination Jack's reign was broken by WBridge5 from France in the final of 2005 (2nd). Jack recaptured the title in 2006. In 2008 Jack won the Round Robin far ahead of the field but lost the final with a smaller margin. In 2009, it was Jack who reclaimed the title in a direct match against WBridge5, succesfully defending it again in 2010.
Results: 2000: 3, 2001: 1, 2002: 1, 2003: 1, 2004: 1, 2005: 2, 2006: 1, 2007: 3, 2008: 2, 2009: 1, 2010: 1.

RoboBridge was written by Job Scheffers from the Netherlands. When Job started playing bridge back in 1982 he had some trouble memorising all the bidding rules. The program was started as a bidding program, to assist his own bidding training. 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.

Shark Bridge

Shark Bridge was written by John Norris from Denmark. Somewhere around 1995 John 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.
Allthough it finished last, Shark Bridge performed well grabbing 5 VP's, or more, from all of its opponents. Two new contestants entered the 2007 championship and both finished behind Shark Bridge.

WBridge5 was written by Yves Costel from France.

WBridge5 is the World Champion of 2005, 2007 and 2008. WBridge5 had already been very close to the ACBL Computer Bridge World Championship title for a few times. Losing the final to Jack by 1 IMP in 2002, WBridge5 had one foot in the final of 2003 when Bridge Baron pulled a stunt and WBridge5 didn't make the final by just a few points.
In 2005 WBridge finally got the title. In the final, that was broadcasted live on Bridge Base Online, 4-time reigning World Champion Jack was defeated. In 2006 Jack recaptured the title, to loose it to WBridge5 again in 2007. In 2008 it was WBridge5 again, to switch back to Jack again in 2009, 2010 and 2012.
