GRANDMASTER CHESS

Moves are entered simply by typing the grid reference of the square to move from, followed by the square to move to, then RETURN. e.g. E2E4 RETURN. You can correct wrong moves by using the DEL key.

The number next to the letter P indicates GRANDMASTER’S current depth of analysis, e. g. P3 means that GRANDMASTER has analyzed one move for himself, one move for you, and another for himself. The best move that he has found so far is displayed below.

The number next to the letter L indicates the playing level. This can be changed by pressing L followed by 0-9.

Excerpts taken from “GRANDMASTER CHESS” Instructions.

Grandmaster Chess plays a surprisingly good game considering it was sold in 1982. At that time it may have been the strongest chess program available on Home Computers. It would be nice to know who programmed the Chess Software.
