Chessmaster 4000 Turbo, however, combined many sophisticated features and a stronger chess engine to form a more serious chess program. With its wide range of features and beautiful graphics, the Chessmaster-programs mostly appealed to the novice and the average chessplayer. Each version has offered more features than its predecessor and a modified chess engine. The first version of Chessmaster, Chessmaster 2000, appeared in the mid-eighties on the Amiga/Atari and was later transferred to the PC. All I ask is minimal assistance from you during the troubleshooting process. In the extremely rare event I cannot get this title to work on your system I will take it back for a full refund. Rapid response technical support for three years is always an e-mail or phone call away. Want the game off your computer? Click Uninstall.
