HITECH
Dr. Hans Berliner, a former world correspondence champion himself with Carl Ebeling, Murray Campbell, Andrew James Palay, Gordon Goetch & Chris McConnell, programmed a chess engine named HITECH, which won Pittsburgh masters’ tournament with a performance rating of over 2400, the North American computer championship in 1986, and then the 1988 Pennsylvania State Chess Championship outright after defeating International Master Ed Formanek (2485) in the last round. It was the first computer program to become a U.S. Chess Federation Senior Master and the first to beat a Grandmaster (defeated GM Arnold Denker 3½-½). In 1990 Hitech won the AEGON-90 tournament in the Netherlands beating in a game the former world title challenger David Bronstein.
