Ed Trice
Full nameEdward A. Trice
Country United States

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. He is a USCF rated Class-D chess player with a rating of 1303. He is also a Gothic Chess expert with a Gothic Chess rating of 2046.

Chess

Trice wrote a chess program called The Sniper, which in April 1987, was the first software program to eclipse the Elo performance rating of 2200, which is equivalent to that of "United States Chess Federation Master". The Sniper ran on processors no faster than 16 MHz, and achieved this result 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.

Gothic Chess

Main article: Gothic Chess
Ed Trice playing Grandmaster Susan Polgar.

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. It should be pointed out that Gothic Chess is closer to Bird's Chess (first proposed by Henry_Bird of Great Britian in 1874) than Capablanca's Chess.

Collaborating with Gil Dodgen, Trice produced a Gothic Chess program named Gothic Vortex, which was based on the chess program Crafty by Robert Hyatt. In 2004, the first ever Gothic Chess Computer World Championship was held, fielding entrants from four different countries. Gothic Vortex, with its ability to announce checkmate from a distance of 268 moves, won by the score of 14-0.

Checkers

In 2003, Trice and 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 a so-called "Perfect Play Lookup" database to demonstrate how to potentially postpone a loss indefinitely. Dodgen and Trice were the first to implement such technology. In 2007, Jonathan Schaeffer solved the game of checkers, and acknowledged Trice and Dodgen's database verification.
