Pretty interesting move there, it might be non optimal against someone who happens to also play the KID but for the 'purist' Grunfeld player it might be a real pain in the ass.
Personally, I think that something like 3...e6!? could make white just as unconfortable and from a practical point of view might be the best try, otherwise it wouldn't be bad to learn a favorable variation in the KID but that would be exactly what the white player expects. Another interesting try is 3...Nd4!?, 4.f3-Nf6! 5.e4, luring the white pawns forward in the same fashion as in Alekhine's defense.

Any thoughts on this system?
