'''Cyrus''',<br/><br />
[[Richard Lang|Richard Lang's]] first chess program, written in [[Assembly]] for a [[Z80]] CPU. Starting programming in January 1981, his tournament debut at the [[European MCC 1981|2nd European Microcomputer Chess Championship]] at the [[Personal Computer World|PCW]] Show 1981 in London was already a breakthrough. Cyrus was the clear winner with 5 out of 5 in a field of 12 Micros. Cyrus ran on a [https://en.wikipedia.org/wiki/Nascom Nascom] microcomputer using a 4 MHz Z80 CPU, and Lang immediately was offered two contracts by [[David Levy]] and [[Kevin O’Connell]], one for Cyrus, and one to work as programmer for [[Intelligent Software]]. Lang accepted, and ''Cyrus IS-Chess'' for the [[ZX Spectrum|Sinclair ZX Spectrum]] was his first commercial entry, followed by programs for various [[Dedicated Chess Computers|dedicated chess computers]] merchandised by ''Intelligent Software'', as well a further improved version of Cyrus, Cyrus II. In an 2003 interview, Richard Lang stated that there is still much of Cyrus in current versions of [[Chess Genius]]. For example, he had never used [[Quiescence Search|quiescence searches]] and relied instead on a [[Static Exchange Evaluation|static swap off routine]] <ref>[http://www.chesscomputeruk.com/Richard_Lang_Q_A.pdf Richard Lang - Question & Answer Interview given to a German magazine in 2003], pdf hosted by [[Mike Watters]], [http://www.chesscomputeruk.com/index.html Chess Computer UK]</ref>. <br />

<br />
Working for [[Intelligent Software]], Richard Lang continued the Cyrus development including a [[6502]] port to cover the growing market of [[Apple II]] and [[Commodore 64]] [https://en.wikipedia.org/wiki/Home_computer home computers]. <br />
<br />
At the [[European MCC 1982|3rd European Microcomputer Chess Championship]], September 1982, [[La Regence]] became strong runner up behind [[Advance|Advance 2.4]], while Cyrus II itself didn't quite come up to its expectations.

In about 1983 Richard Lang started to write his new program [[Psion]] for [[68000]] family of processors, and was about to abandon the work for [[Intelligent Software]], who continued their own work by owning the Cyrus brand by primary programmer [[Mark Taylor]], yielding in [[Cyrus 68K]]. Its predecessor, competing under the name ''65 Cyrus X'' at the [[WMCCC 1983]] in [https://en.wikipedia.org/wiki/Budapest Budapest] is assigned to ''Intelligent Software'' with the authors [[David Levy]], [[Mark Taylor]] and [[Kevin O’Connell]] at the [[ICGA]] tournament page <ref>[https://www.game-ai-forum.org/icga-tournaments/program.php?id=405 Cyrus' ICGA Tournaments]</ref>.<br />
