Source-derived summary

Tigran Vardani Petrosian was a Soviet-Armenian chess grandmaster. The ninth World Chess Champion from 1963 to 1969, he was nicknamed "Iron Tigran" due to his almost-impenetrable defensive playing style, which emphasized safety above all else. Petrosian is often credited with popularizing chess in Armenia.

Editorial summary

This brief starts where responsible research should: with the source description of “Tigran Petrosian” as soviet-Armenian chess grandmaster (1929–1984). Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—1963, 1969—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Tigran, Petrosian and Soviet-Armenian can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as soviet-Armenian chess grandmaster (1929–1984). Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 5, 2026. The first chronological checks are 1963 and 1969.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
