Colossus Chess 4 Spectrum 48/128/+2

Colossus is probably the most complete chess program available for any home computer, written using the very latest techniques. It has the widest range of true features available, including some before implemented.

Colossus also has a perfect understanding of all the rules of chess, including under-promotion, the fifty move rule and all draws by repetition. It can also handle all the standard mates, including King, Bishop and Knight versus King.

Colossus offers the choice between the usual two dimensional flat board display or the three dimensional real life board which allied to optional joystick control makes it clear and easy to use.
