Cyber Chess is a chess-playing computer program developed by William Tunstall-Pedoe.[1][2] It was written for the Acorn Archimedes and published commercially by The Fourth Dimension.[2][3][4][5][6][7]


Evaluation of moves was tuned by use of a genetic algorithm.[8]


The game provides play against another human or the computer (at various levels of difficulty). Saved games and graphics export as vector Drawfiles are supported.[9]


In Acorn User's games review of 1993/94, Cyber Chess was listed number 55 in the Best 100 Games.[10] The game was well received by the magazines Acorn Computing[5] and Archimedes World,[6] but the retail price of £35 was criticised by The Icon Bar in an article about the marketing of RISC OS games.[11]
