Software developer edit
Kaplan had always been interested in computer chess throughout his career, and this led him to found Heuristic Software Corporation,[6] whose first development was Heuristic Alpha in 1990–91,[7] which eventually evolved into Socrates and later Socrates II.
Socrates II was one of the corporation's most successful programs, winning the 1993 ACM International Chess Championship[8] after defeating opponents with special-purposed hardware and software for playing chess, like HiTech[9] and Cray Blitz,[10] even though Socrates II ran on a stock 486 PC.
These achievements drew Electronic Arts's attention, and the company proceeded to hire Kaplan's development team to develop Kasparov's Gambit, incorporating former world chess champion Garry Kasparov as brand name and adviser.[11] Kasparov's Gambit was the first and sole effort of Electronic Arts to enter the chess market.
