From an interview I had with Yochanan Afek in the 'Chess House' (the headquarters of the Israeli Chess Association in Ramat Aviv, Israel):
[Young man passes us, waves to Afek; Afek exchanged a few polite words.]
Afek: You know who this was?
Me: No.
Afek: It's Mikhail Botvinnik. No, not that one, of course; it's just his name.
Me: With a name like that, he must be a good player...
Afek: Pretty decent! He's a master who played in some international youth tournaments. By the way, in one of those, he played a young Armenian player with an interesting name...
Me: Armenian? Don't tell me... isn't there a young player called...
Afek: ...yes, Tigran Petrosian!
