CheckerBoard lets you play checkers against your computer against different opponents. The built-in AI engine plays checkers at superhuman strength with an huge opening book and endgame databases with perfect knowledge of all positions with 6 pieces or less (8-piece database available as optional download). You can save, load, analyze and publish games. Further goodies are a database of grandmaster games and a checkers tutorial by English grandmaster Richard Pask. The database is searchable by player name or by position. Engines for other checkers variants (Italian, Spanish) are also available.
