It was a four round Swiss tournament, with both Belle and CHAOS finishing with 3½. The championship was decided by the most exciting game of the tournament, a playoff between Shannon's Type A versus Type B strategy in presence of its innovator, which was won by Belle, the type A brute force program with about 1000 times more nodes per second.
It was remarkable that in the round three game of CHAOS versus Nuchess[12] , almost the same book-line occurred as six years before at WCCC 1974 in the game of CHAOS versus Chess, both programs with David Slate involved. In 1974 CHAOS already played 16 NxP!! - a move which has been acclaimed as the finest ever made by a computer of that time, as mentioned by Alex Bell[13] .
Truscott and Wright continued to participate in the Chess Tournaments and in 1980 they competed in the 3rd world Computer Chess Championship held in Linz, Austria. Thompson and Joe Condon, who was a researcher at Bell Labs, were also in the competition. Truscott notes that Thompson and Condon "had completed their hardware chess machine and snagged first place. Duchess came in third. And Claude Shannon was in attendance, and even handed out the trophies at the awards ceremony. Afterwards we all went over to a TV studio to watch a West German TV special on computer chess and the championship. Claude Shannon and his wife were very engaging people. Someone took a photo of all of us, I have a copy buried somewhere".
