The ACM's Twelfth North American Computer Chess Championship (NACCC) was held from November 8 to 11, 1981 at the Bonaventure Hotel, Los Angeles, California, USA [1] .

Mike Valvo acted as Tournament Director, replacing David Levy, who previously served in that capacity and was expected to enter his own program. Tournament guests were Shelby Lyman [2], chess commentator for WNET's television chess shows and emcee for the Fisher-Spassky World Championship Match in 1972 [3] , and Isaac Kashdan, Chess Editor for the Los Angeles Times. A computer chess panel discussion and short paper presentation was part of the technical program [4] .
