Editing GNU Go (section)

== Strength ==
At this level of performance, GnuGo was between six and seven stones weaker than the top commercial programs on good hardware as of early 2009, but comparable in strength to the strongest programs not using [[Monte Carlo method]]s. It did well at many [[computer Go]] tournaments. For instance, it took the gold medal at the 2003 and 2006 [[Computer Olympiad]]<ref>{{cite web|url=http://www.computer-go.info/events/index.html|title=Computer Go - Past Events}}</ref> and second place at the 2006 Gifu Challenge.<ref>{{Cite web|url=http://computer-go.softopia.or.jp/gifu2006/English/08.html|title=Gifu Challenge 2006|access-date=21 June 2007|archive-url=https://web.archive.org/web/20070703231248/http://computer-go.softopia.or.jp/gifu2006/English/08.html|archive-date=3 July 2007|url-status=dead}}</ref>
