The new World Computer Bridge Champion is Jack, developed by Hans Kuijf of the Netherlands. In the 64-board final of the World Computer Bridge Championship, Jack beat Micro Bridge (Tomio and Yumiko Uchida of Japan), 136-84.

In addition to the main competition there were exhibition matches pitting humans against computers. Jack and Micro Bridge joined as teammates and played eight-board matches against two different teams. One team was a team of International stars, Jacek Pszczola-Piotr Gawrys and Sam Lev-Pinhas Romik, who defeated the computer team by 18 IMPS. Another team of star players, Lisa and David Berkowitz and Marty Fleisher-JoAnnA Stansby, defeated the computers by 8 IMPs.

The players apparently enjoyed the experience, while the computers immediately showed a screen saver with the expression…wait until next year. Zia also came to play but the computers seemed to remember him and, sensing defeat, they shut down permanently.

Jack's developer, Kuijf, said the play engine for the program is four or five years old. The bidding part was first written in April of 2000. The way Kuijf decided on the name of the program is interesting. He is also a chess player, and he had a chess program called King. When he started on his bridge program, he called it Queen, but in the early stages of its development the program didn't perform particularly well, so it got a "demotion" from Queen to Jack.

Kuijf, who lives in The Hague area in the Netherlands, said he may publish a Dutch version of the program for commercial purposes by the end of the year. He isn't certain whether he will do one in English.

In an attempt to standardize alerts for the sanctioned Word Computer Bridge Championships (WCBC), a 'table manager' program was written by Blue Chip Bridge and all contestants 'plug in' so as to communicate with others. Not all interested programs were able to get this feature ready for this year's event, unfortunately, but enough to make it a go.

Last yearís winner, Meadowlark Bridge experienced technical difficulties in its program and will not be ready in time to defend its title.

Also, GIB who won the World Computer Bridge Championship in Bermuda, stated other promotional events prevented the program from arriving in time.

BRIDGE FORUM co-ordinator, Avrom, has been doing a lot of the ground work and will continue to do so. Between the two of us we will let you know IF the GIB event does take place and more on the WCBC. We should have some results tonight given the first cycle ends today.

Conditions of contest are at the website. It was decided by the participants to run a double round robin, with the top two programs squaring off in a 64-board final.

The ACBL's fifth annual World Computer Bridge Championship starts today and continues through Saturday, when the final will take place. Six programs from six different countries are scheduled to compete. The format will be a double round-robin coming down to two finalists. Matches will be played in the Saskatchewan Room on the mezzanine level at the Royal York Hotel.

Last year's championship was played in Maastricht, the Netherlands, in conjunction with the World Bridge Federation's World Bridge Team Championships. For a history of this event event see allevy/Maastricht.

Last year's champion, Meadowlark, has withdrawn from this year's competition, citing programming difficulties. The contestants are Blue Chip Bridge from the UK, Bridge Baron from the U.S., Micro Bridge from Japan, Q-Plus Bridge from Germany, WBridge5 from France and Jack from the Netherlands.

An exhibition pitting three top human teams against computer opponents will take place later in the week. Times and participants will be announced later, but Zia has said he wants in.

Digital Data Answers

1. Bridge Baron, developed by Tom Throop in 1979, and currently in version 11 for Windows and Macintosh.

2. Meadowlark Bridge, developed by Rodney Ludwig of the US. Technical difficulties with the program at this time have prevented Meadowlark from participating this year.

3. With instructional software such as those mentioned, one gets constructive lessons and predealt hands that aim to help raise the level of one's game. The programs in the WCBC are designed to think, and thus raise the level of one's game against other computers and humans.

4. Q-Plus, developed by Hans Leber of Germany, lost to Bridge Baron in Albuquerque, GIB in Bermuda, and was nipped on the last board of the final at Maastricht by Meadowlark Bridge.

5. As detailed in the book, "Man Versus Machines" by Marc Smith, some two years ago, Zia Mahmood faced seven computer programs in a series of matches

6. Q-Plus. On some online sites robots — also known as 'bots' — are used to fill a table if need be.

7. GIB, developed by Matthew Ginsberg of the US. GIB was invited to participate this year, but declined, saying other promotional events prevented his appearing.

8. Omar Sharif, whose name graces a program for the PC ("Omar Sharif on Bridge") and Macintosh ("Omar Sharif's Bridge Deluxe").

9. Al Levy, ACBL District 24 Governor, proposed the annual competition in 1996, and the first WCBC was held at the Albuquerque NABC in 1997.

10. "Chess is a game of perfect information and therefore a deterministic game. Bridge is a game of incomplete information and therefore a game of probability." — quoted from Al Levy's report on the Maastricht WCBC in the International Computer Games Journal, December 2000.
