Marion Franklin Tinsley was an American mathematician and checkers player. He is considered to be the greatest checkers player who ever lived. Tinsley was world champion from 1955–1958 and from 1975–1991 and never lost a world championship match. He lost only seven games from 1950 until his death in 1995. He withdrew from championship play during the years 1958–1975, relinquishing the title during that time.

It was developed between the years 1989 to 2007 at the University of Alberta, by a team led by Jonathan Schaeffer and consisting of Rob Lake, Paul Lu, Martin Bryant, and Norman Treloar.
