It's hard to believe that it's been over a decade since One Jump Ahead: Challenging Human Supremacy at Checkers was published. I'm delighted to have the opportunity to update and expand the book. The first edition ended on a sad note and that was reflected in the writing. It is now eleven years later and the project has come to a satisfying conclusion. Since its inception, the checkers project has consumed eighteen years of my life twenty if you count the preChinook and postsolving work. It's hard for me to believe that I actually stuck with it for that long. My exwife, Steph, would probably have something witty to say about my obsessive behavior. Rereading the book after a decade was difficult for me. When I originally wrote One Jump Ahead, I vowed to be candid in my telling of the story. That meant being honest about what went right and what went wrong. I have been criticized for being hard on some of the characters. That may be so, but I hope everyone will agree that the person receiving the most criticism was, justifiably, me. I tried to be balanced in the storytelling, reflecting things as they really happened and not as some sanitized everyonelivedhappilyeverafter tale.
