"Schaeffer has also released an updated version of a draughts-playing programme called Chinook. In the 1990s, this program failed to beat the then world champion Marion Tinsley, who is widely regarded as the greatest Checkers player ever. Before his death, in 1995, Tinsley lost only 9 games in a 45-year playing career."
Even in the 90's the best computer program couldn't beat him, I don't think the same is true of chess programs at the time and top level players. That says a lot about either the man, or the lack of interest in checkers programs.
45 years of tournament play and he lost only 9 games? Has any chess player ever come close to that? Tinsley was a checkers playin' demon!
By the way, how do you pronounce "draughts"? Is it drafts? Drawts? WHAT??
