The '''Second Computer Olympiad''' was held from August 15 to 21, [[Timeline#1990|1990]], in the Octagon library of [[Queen Mary, University of London|Queen Mary & Westfield College]], [https://en.wikipedia.org/wiki/London London], [https://en.wikipedia.org/wiki/United_Kingdom United Kingdom]. In [[2nd Computer Olympiad#Chess|Chess]], [[Mephisto]] by [[Richard Lang]] took revenge on [[Rebel]], first time running on an [[ARM2]] processor, from [[1st Computer Olympiad#Chess|last years]] defeat and managed a 100% score. Newcomer [[Zugzwang (Program)|Zugzwang]] was a great surprise, and [[Kaissa#PC]] was a new program with an old name, developed by a 9-member team around [[Mikhail Donskoy]] <ref>[[Zsuzsa Horváth]] ('''1990'''). ''Report on the 2nd Computer Olympiad''. [[ICGA Journal#13_3|ICCA Journal, Vol. 13, No. 3]]</ref>. The second Computer Olympiad was again associated by the [[2nd Computer Olympiad#Workshop|Heuristic Programming in Artificial Intelligence]] workshop, soon followed by [[Advances in Computer Chess 6]]. Proceedings were edited by [[David Levy]] and [[Don Beal]], published in 1991 <ref>[[David Levy]], [[Don Beal]] (Eds.) ('''1991'''). ''Heuristic Programming in Artificial Intelligence - The Second Computer Olympiad''. Ellis Horwood</ref>.

The '''Second Computer Olympiad''' was held from August 15 to 21, [[Timeline#1990|1990]], in the Octagon library of [[Queen Mary, University of London|Queen Mary & Westfield College]], [https://en.wikipedia.org/wiki/London London], [https://en.wikipedia.org/wiki/United_Kingdom United Kingdom]. In [[2nd Computer Olympiad#Chess|Chess]], [[Mephisto]] by [[Richard Lang]] took revenge on [[Rebel]], first time running on an [[ARM2]] processor, from [[1st Computer Olympiad#Chess|last years]] defeat and managed a 100% score. Newcomer [[Zugzwang (Program)|Zugzwang]] was a great surprise, and [[Kaissa#PC]] was a new program with an old name, developed by a 9-member team around [[Mikhail Donskoy]] <ref>[[Zsuzsa Horváth]] ('''1990'''). ''Report on the 2nd Computer Olympiad''. [[ICGA Journal#13_3|ICCA Journal, Vol. 13, No. 3]]</ref>. The second Computer Olympiad was again associated by the [[2nd Computer Olympiad#Workshop|Heuristic Programming in Artificial Intelligence]] workshop, soon followed by [[Advances in Computer Chess 6]]. Proceedings were edited by [[David Levy]] and [[Don Beal]], published in 1991 <ref>[[David Levy]], [[Don Beal]] (Eds.) ('''1991'''). ''Heuristic Programming in Artificial Intelligence - The Second Computer Olympiad''. Ellis Horwood</ref>.
