I really can't say I have figured out already one single question of your last post. But again it seems advisable to take a look at the Pirc proper first.
1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Be3 c6 and again I am not satisfied with the Argentine/150-Attack 5.Qd2 b5 6.f3/6.Bd3.
So I recommend 5.h3 Bg7 6.f4. When Black plays ...b5, White always has the choice between e5 and Bd3. I think this very attractive.
In the Robatsch move order we get: 1.e4 d6 2.d4 g6 3.Nc3 Bg7 4.Be3 c6 5.f4 b5
a) 6.h3 The question is now, if Black can postpone ...Nf6 to his benefit; else it will become the Pirc.
b) 6.Bd3 Nd7 7.Nf3 might be more precise, only playing h3 immediately after ....Nf6.
I don't like an early Qd2 very much. This costs a valuable tempo, if White follows the well known plan from the GPA: Qd1-e1-h4, f5, Bh6, Ng5 and mate. From White's point of view the moves (after 5.f4) Nf3, Bd3 and 0-0 are necessary. The early ...b5 makes castling queenside hazardous. So why play 7.Qd2, as Speelman and McDonald recommend?
These are general considerations. I have yet to back this up with concrete lines and that will take quite a long time.
5...Nd7 with the idea of an early ...e5 is another idea which I haven't investigated yet.
Michael, please have mercy. I have not even finished the Ujtelky Defence (4.Be3 a6) yet.
