I don't claim to be an expert, but I have surprised people with the Russian Variation against the Grunfeld. (I looked it up in the database: Kasparov, Smyslov, Karpov, Petrosian, Anand, Ivanchuk, Kramnik, Carlsen, Topalov, Aronian and Giri have played this line against the Grunfeld.)
But there is NO transposition here, this is simply a DIFFERENT opening.
Man, I should get back to this forum, when people learn some good openings.
No one has claimed that there is a transposition here, the text was used as an analogy only. Please try to be more aware.
