This work remains a milestone in AI research. Samuel's program reportedly beat a master and "solved" the game of checkers. Both journalistic claims were false, but they created the impression that there was nothing of scientific interest left in the game (Samuel himself made no such claims). Consequently, most subsequent game-related research turned to chess. Other than a program from Duke University in the 1970s (Truscott 1979), little attention was paid to achieving a world championship-caliber checker program.

Samuel's successes included a victory by his program over a master-level player. In fact, the opponent was not a master, and Samuel himself had no illusions about his program's strength. This single event, a milestone in AI, was magnified out of proportion by the media and helped to create the impression that checkers was a solved game. Nevertheless, his work stands as a major achievement in machine learning and AI. Since 1950, the checkers world has been dominated by Tinsley.

Long-time world checkers champion Marion Tinsley consistently bested all comers, losing only nine games in the 40 years following his 1954 crowning. He lost his world championship title to a computer program in 1994 and now that same program has become unbeatable; its creators have proved that even a perfectly played game against it will end in a draw. Jonathan Schaeffer and his team at the University of Alberta, Canada, have been working on their program, called Chinook, since 1989, running calculations on as many as 200 computers simultaneously. Schaeffer has now announced that they have solved the game of American checkers, which is played on an 8 by 8 board and is also known as English draughts. The team directed Chinook so it didn't have to go through every one of the 500 billion billion (5 * 1020) possible moves.

Checkers computer becomes invincible

An invincible checkers-playing program named Chinook has solved a game whose origins date back several millennia, scientists reported Thursday on the journal Science's Web site. By playing out every possible move -- about 500 billion billion in all -- the computer proved it can never be beaten. Even if its opponent also played flawlessly, the outcome would be a draw. Chinook, created by computer scientists from the University of Alberta in 1989, wrapped up its work less than three months ago. In doing so, its programmers say the newly crowned checkers king has solved the most challenging game yet cracked by a machine -- even outdoing the chess-playing wizardry of IBM's Deep Blue.
