"In the 1990s, world chess champion Gary Kasparov played two historic matches against IBM's Deep Blue supercomputer. He won the first match but lost the second by just a single point. As a graduate student at Stanford writing a thesis on artificial intelligence at that time, I was fascinated by the match. I'd been a computer hobbyist since the 1980s as well as a chess buff. Over the years I've tried practically every commercially available chess program on every platform, including Sargon, Socrates, Chessmaster, and others. I used TRS 80 and Apple II computers, and then IBM PCs running DOS, followed by Macintosh and Windows systems. Since that time I've wanted a chess computer as powerful as Deep Blue - my own world-champion-level sparring partner."
