Hi.
If you know that playing the KID is the ultimate goal, in other words not using any irregular options stemming from waiting with Nf6, then move order would indeed likely matter a lot less. It could still matter a little bit in subtle ways though. E.g.:
- There are some early deviations that can be made less likely depending on move order chosen.
- In principle one can somewhat benefit from considering what move order the opponent would waste most time in the opening thinking about.
- Just being able to threaten some non-KID transposition could still bring a reaction from the opponent; even if there is no actual intent to go for the line the opponent doesn't like.
When it comes to how a Pirc or modern player should handle the 1.d4 openings.If not entering the proper KID, Grünfeld or Modern Benoni you tend to have to puzzle together responses that fail to enter these major openings for all white early move sequences.
The reason I focused on 1.d4 with g3 to follow immediately or after one or two moves is that it always seems hard to find something that is not just a transposition to a KID or Grünfeld there. If, however, you can
go for 1...g6 and these types of mostly irregular Benko type lines I proposed previously... There is not to much saying you shouldn't be able to do that against fianchetto setups from white and play 3...d6 to attempt re-entering non-Nf6 KID lines if white doesn't go for a fianchetto setup. I don't think there are very significant benefits for white players not aiming to fianchetto when black goes 1...g6, 2...Bg7 and 3...d6 instead of 1...d6, 2...g6 and 3...Bg7. You lose the options, as black, to aim for 1.d4 d6 2.c4 e5, 1.d4 d6 2.Nf3 g6 3.c4 Nf6 4.Nc3 Bf5 and 1.d4 d6 2.c4 g6 3.e4 e5, but none of these lines seem like lines critical for a repertoire to me.
I think a 1.d4 g6 repertoire where, as black, you basically never enter any of KID/Grünfeld/Modern Benoni would be quite possible. That would also confuse white players a lot.
