This may sound like an odd suggestion but the book "One Jump Ahead: Computer Perfection at Checkers" by Jonathan Schaeffer is a surprisingly interesting book. The author is a computer science professor in Canada who describes his attempt to solve the game of checkers, as part of a broader effort to build the best checkers-playing software program in the world. In the book, he goes into detail about the world of international competitive checkers matches and the impact that having a computer beat the reigning world champion has on that unique subculture. I was surprised that I couldn't put the book down once I started reading it.
I learned Marion Tinsley's story from Jonathan Schaeffer's book, <em>One Jump Ahead</em>.
Schaeffer headed the team at the University of Alberta that solved the game of checkers in 2007.
