Former Edmonton Convention Centre [1]

The Sixth World Computer Chess Championship took place from May 28 to 31, 1989, in the Edmonton Convention Centre, Edmonton, Alberta, Canada. It was held in conjunction with Congress '89 [2] of the Canadian Information Processing Society (CIPS), and was sponsored by Alberta Government Telephones (AGT) [3]. Tony Marsland's hard work in obtaining funds and recruiting attendees was apparent in the impressive chess expertise available to comment on the event - he further organized the New Directions in Game-Tree Search two-day workshop during the tournament. 24 teams from 9 nations participated. Canadian Chess Champion Kevin Spraggett was present commentating on the games along with David Levy, Mike Valvo, Danny Kopec, Julio Kaplan and David Slate. A large crowd of about 300 were on site during most of the games [4] . Deep Thought won with a perfect score, winning all five games - runner up was Bebe.

Tournament Director


The Workshop New Directions in Game Tree Search was organized by Tony Marsland [16] and held in conjunction with the WCCC on May 29 and 30, 1989. Revised contributions of the workshop were published in Computers, Chess, and Cognition.

Session 1

The first session was disclosed by John McCarthy mentioning the often cited metaphor of computer chess as the Drosophila of artificial intelligence research, and attributed it to Alexander Kronrod [17] :

Session 2

The second day began with opening remarks by Claude Shannon, who recalled that in the 40s relays rather than transistors were the state of the art. He still feft that games were an excellent test bed for understanding intelligence, and predicted that within the next 25 years computers would outplay the best humans at chess [18] :

Congress '89

John McCarthy and Donald Michie were invited speakers of the Congress '89 conference of the Canadian Information Processing Society on May 31, 1989 [19] . Their presentations were also published in Computers, Chess, and Cognition:
