This is the electronic chess game built with a realistic set of moves that challenges every ability level from novice to master. Play-tested by the University of Chicago Chess Team, the set's 64 levels offer eight built-in classical mate studies, allowing players to select between hint, training, and coach playing modes. With a Swedish ELO rating of 2,200, it allows players to set up positions for further study and take back up to 200 moves—players can even watch the computer as it "thinks" about its next move. Easy to use, playing spaces are lit with LEDs to indicate clear movement. Includes AC adapter (or requires six AA batteries). Chessboard 8" sq. (4 lbs.)
