Commodore 64 Emu Cyrus II (1986)

CYRUS II was written by Richard Lang and published in 1986. CYRUS II plays quite a good game but is let down with it’s inability to Ponder while waiting for it’s opponent to move. The chess board and graphics are simple but effective.

The PC direction keys can be used to play CYRUS II. Pressing SPACE BAR at any time takes you to the Analysis Screen.
