Man Vs. Machine World Champion
Chinook is the first computer program to win the world champion title in a competition against humans. In 1990 it won the right to play in the human World Championship by being second to Marion Tinsley in the US Nationals. At first the American Checkers Federation and English Draughts Association were against the participation of a computer in a human championship. When Tinsley resigned his title in protest, the ACF and EDA created the new title Man vs. Machine World Championship, and competition proceeded. Tinsley won with four wins to Chinook's two, with 33 draws.
In a rematch, Chinook was declared the Man-Machine World Champion in checkers in 1994 in a match against Marion Tinsley after six drawn games, and Tinsley's withdrawal due to pancreatic cancer. While Chinook became the world champion, it never defeated the best checkers player of all time, Tinsley, who was significantly superior to even his closest peer.
In 1995, Chinook defended its man-machine title against Don Lafferty in a 32 game match. The final score was 1–0 with 31 draws for Chinook over Lafferty. After the match, Jonathan Schaeffer decided not to let Chinook compete any more, but instead try to solve checkers. It was rated at 2814.

Famous quotes containing the words man, machine, world and/or champion:
“Conversation is an art in which a man has all mankind for his competitors, for it is that which all are practising every day while they live.”
—Ralph Waldo Emerson (1803–1882)
“... in the fierce competition of modern society the only class left in the country possessing leisure is that of women supported in easy circumstances by husband or father, and it is to this class we must look for the maintenance of cultivated and refined tastes, for that value and pursuit of knowledge and of art for their own sakes which can alone save society from degenerating into a huge machine for making money, and gratifying the love of sensual luxury.”
—Mrs. H. O. Ward (1824–1899)
“All grandeur, all power, all subordination to authority rests on the executioner: he is the horror and the bond of human association. Remove this incomprehensible agent from the world and at that very moment order gives way to chaos, thrones topple and society disappears.”
—Joseph De Maistre (1753–1821)
“Let’s not quibble! I’m the foe of moderation, the champion of excess. If I may lift a line from a die-hard whose identity is lost in the shuffle, “I’d rather be strongly wrong than weakly right.””
—Tallulah Bankhead (1903–1968)
