Editing Tigran Petrosian (section)

== Olympiads and team championships ==
Petrosian was not selected for the Soviet [[Chess Olympiad|Olympiad]] team until 1958; though he had already been a Candidate twice by that time. From that point, however, he made ten straight Soviet Olympiad teams from 1958 to 1978, won nine team gold medals, one team silver medal, and six individual gold medals. His overall performance in Olympiad play is impressive: +78−1=50 (only one game lost, to Robert Hübner, out of 129 played), or 79.8 percent, the all-time third-best performance after [[Anatoly Karpov]] (+43−2=23 or 80.1 percent) and [[Mikhail Tal]] (+65−2=34 or 81.2 percent).<ref name="olimpbase">[http://www.olimpbase.org/players/ikkqkgyh.html Petrosian, Tigran] team chess records at olimpbase.org</ref>
