"In March 1998, the New York Times sponsored an exhibition match between MAVEN and a team consisting of world champion Joel Sherman and runner-up Matt Graham. It is not clear whether the collaboration helped or hindered the human side, but the computer won convincingly by a score of six wins to three. The result was not an anomaly. In July 1998, MAVEN played another exhibition match against Adam Logan (at AAAI-98), scoring nine wins to five."
