Participants
The Tournament
The defending champions had completely rewritten their program using Shannon's type A strategy and renamed it Chess 4.0. They did it again, but not with a 100% score - after winning three ACM tournaments and ten consecutive tournament games, it only managed to draw from Dartmouth CP in round 2 - being in trouble most of the game, Dartmouth CP repeated the position for the third time while one pawn ahead. In the third round Tech 2 defeated Dartmouth CP, Chess 4.0 defeated Coko 4 and CHAOS won its third straight game to take the lead in the tournament. The last round pitted Chess 4.0 against CHAOS - the winner would win the tournament. The game was a highly tactical one in which the large trees examined by Chess were too much for CHAOS to handle. On the last evening of the tournament, after the Chess 4.0 versus CHAOS game was completed, Charles Kalme played both programs in a simultaneous exhibition with a Queen handicap. He won the game against CHAOS (and a $100 side bet) but lost from Chess 4.0 [5] .
