Cyrus is the 2nd Chess game that Radio Shack put out... this one came out 2 years after the original Microchess. This one has a more intelligent computer player, and a lot more options, than the original Chess game. It has options to take back moves, to auto-play (computer can take over a move at any time), provide hints for the human player, and allow you to switch sides at any time.
