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, which has 80 squares (instead of 64) with two new chess pieces. He has also written programs to play the games of chess, checkers, and Gothic Chess.
Gothic Chess
In 2000, Trice patented the commercial 80-square chess variant Gothic Chess, derived from Capablanca Chess and an earlier version by Henry Bird. This variant places the new pieces, the Chancellor and the Archbishop, on each side of the King.[2]
In 2004, Trice organized the Gothic Chess Computer World Championship, which was won by his own Gothic Vortex computer program.[3]
Chess
In 1987, Trice wrote a chess program called The Sniper. Capable of running on a home computer of the time, this was the first software program to eclipse the Elo performance rating of 2200,[citation needed] 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.[4]
In 1989, he won an exhibition game against the Deep Thought chess program in 20 moves,[5] its quickest loss ever.[6]
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).[7] Their World Championship Checkers computer program was the first to use their database and methodologies.[8] In 2007, Jonathan Schaeffer solved the game of checkers,[9] and acknowledged Trice and Dodgen's database verification.[10]
