Checkers was one of the very first games to be implemented
on computers, and one of the first to have a successful
playing program. Papers about checkers by Samuel
were probably cited more than any other in the history
of game playing programs. For years, a very
successful program, Chinook, defeated all challengers,
except one lone human expert, Marion
Tinsley. Chinook finally became the undisputed
champion in 1995, when Mr. Tinsley died. Subsequently,
Checkers was solved
in the strictest sense, by generating a complete game
tree, in 2007.
All this applies to the traditional "American Standard"
checkers, which is close to the game you probably played as
a kid, except "jumping own men" is not allowed. There
are hundreds of variants, some regional, some modern.
Boardspace has two interesting variants; Turkish
Checkers and International Checkers.
Beats me (take that literally) but I've never claimed to be
a checker players.
