Edward A. Trice (born December 5, 1966 in Philadelphia, Pennsylvania) is an American inventor and entrepreneur. He invented a chess variant known as Gothic Chess, and has created several chess and checkers programs.
Gothic Chess
Main article: Gothic Chess
In 2000, Trice patented the commercial chess variant Gothic Chess, derived from Capablanca Chess. This variant differs from Capablanca Chess in the initial positioning of some of the back-row pieces.
Chess
Trice wrote a chess program called The Sniper, which in April 1987, which he claims ( no reference of proof given)was the first software program to eclipse the Elo performance rating of 2200, which is equivalent to that of "United States Chess Federation Master", roughly four years after the Belle chess machine became the first ever hardware machine to earn the Master title.
In 1989, he won an exhibition game against the Deep Thought chess program in 20 moves, its quickest loss ever.
Checkers
In 2003, Trice and Gil Dodgen demonstrated that it was possible for a checkers program to fail to win a theoretically-won position with as few as seven pieces on the board (four for the winning side, three for the side that should lose). Their World Championship Checkers computer program was the first to use their database and methodologies. In 2007, Jonathan Schaeffer solved the game of checkers, and acknowledged Trice and Dodgen's database verification.
