I like playing the King's Indian Attack against just about any black setup, except for when black plays the Leningrad Dutch style setup.
I had a look at how white is dealing with this situation and it seems that the double fianchetto with white pawns on b3, c4, d4 and g3 is not bad.
My question is about the different move orders that can lead there.
After 1. Nf3, black can reach his setup via either 1. ... f5 or 1...d6.
Is there any difference between these for the white player?
In which order shall I go for the double fianchetto setup described above?
