What is the purpose of editorial comments in Informants? I was browsing an old Informant today and came across an editorial comment, marked with RR. I've seen several of them at the beginning of a game that reference another game, involving a completely different opening, by other players. What is the purpose of these comments?
RR = Redaction Remark, meaning they consider recommended line to be better, or that the game/line they pointed out is relevant...
