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 1955–1958 and 1975–1991 and never lost a world championship match, and 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. Derek Oldbury, sometimes considered the second-best player of all time, thought that Tinsley was "to checkers what Leonardo da Vinci was to science, what Michelangelo was to art and what Beethoven was to music."
Checkers, also known as draughts, is a group of strategy board games for two players which involve diagonal moves of uniform game pieces and mandatory captures by jumping over opponent pieces. Checkers is developed from alquerque. The term "checkers" derives from the checkered board which the game is played on, whereas "draughts" derives from the verb "to draw" or "to move".
International draughts is a strategy board game for two players, one of the variants of draughts. The gameboard comprises 10×10 squares in alternating dark and light colours, of which only the 50 dark squares are used. Each player has 20 pieces, light for one player and dark for the other, at opposite sides of the board. In conventional diagrams, the board is displayed with the light pieces at the bottom; in this orientation, the lower-left corner square must be dark.

Chinook is a computer program that plays checkers. 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. The program's algorithms include an opening book which is a library of opening moves from games played by checkers grandmasters; a deep search algorithm; a good move evaluation function; and an end-game database for all positions with eight pieces or fewer. All of Chinook's knowledge was programmed by its creators, rather than learned using an artificial intelligence system.
