Lang: 'It was written in such a hurry and the tournament came in the middle of its development period rather than at the end'.

Various programs derivate from Cyrus competed at the [[European MCC 1983|4th European Microcomputer Chess Championship]], September 1983. Cyrus 2.5 finished best (4th) of the home computer programs tied with [[White Knight|White Knight 11]] by [[Martin Bryant]], behind [[Advance|Advance 3.0]] and [[Chess 2001]].
