a [[Parallel Search|multi-processor]] chess engine by primary author [[Giancarlo Delli Colli]], initially written in [[Java]] and later ported to [[Cpp|C++]] based on the source code of [[Fruit]]. Lion participated at the [[CCC 2005]] in [[https://en.wikipedia.org/wiki/Bologna|Bologna]] and the [[WCCC 2006]] in [[https://en.wikipedia.org/wiki/Turin|Turin]]. At the WCCC, after five rounds were played and a protest was filed by a participant, [[Yngvi Björnsson]] and independently [[Jonathan Schaeffer]] inspected Lion's source code and found it a close derivative of [[Fabien Letouzey|Fabien Letouzey’s]] program Fruit, which would have been acceptable if this had been revealed, credit given, and permission received before entering <ref>[[http://www.impalapublications.com/blog/index.php?/search/kasparov/P10.html|Computer Chess – a conversation]], May 30. 2006</ref>. The Lion authors did not deny, and provided their own [[WCCC 2006#TheInterpretationOfRules|interpretation of rules]] since they had included a file crediting the effort by Fabien Letouzey, albeit invisible for other people <ref>[[Jaap van den Herik]] (**2006**). //The Interpretation of Rules//. Editorial, [[ICGA Journal]], Vol. 29, No. 2, [[http://ilk.uvt.nl/icga/journal/pdf/toc29-2.pdf|pdf]]</ref>. Lion++ 1.5 was disqualified according to rule 2 <ref>[[http://www.game-ai-forum.org/icga-tournaments/program.php?id=86|Lion's ICGA Tournaments]]</ref>. The controversial term 'application detail' was later amended by the [[ICGA]] and made explicit as 'submission details' as part of [[ICGA Tournament Rules|rule 2]] <ref>[[http://www.game-ai-forum.org/icga-tournaments/event_info.php?id=12|WCCC Rules (ICGA Tournaments)]], June 11-18, 2007</ref>. ||
