Thanks for the shared analysis!

Against the Austrian with 6.Bd3 & 7.0-0 I almost exclusively played 7...Nc6, but sometimes the tension in the center fizzled out a bit too soon for my taste and it seemed difficult to avoid the outcome with Black.
7...Na6 is of course a very worthy alternative (and I think today even Mainline), as it generates a more strategic and dynamic middlegame fight. So I recently included it in my repertoire and got complex games, experience and feeling for the arising positions still need to be established though. 

When I looked up your book references and refrehed some of my notes, it seemed that 9.Qe2 and 9.f5 post the most (practical) problems for Black - 9.Kh1 (very popular) and 9.a3 (maybe rather played as an SOS on move 6!) I wouldnt consider to be too dangerous.
In general, when Black is able to play both ..Rb8 and ..Bg4 (9.f5 is stopping this of course), he should be quite alright in my opinion, although 9.Qe2 as it prepares e5 and stops ..b5 has to be taken seriously.

Will be interesting to see, how further authors will evaluate these lines in the future! 

Hello.

I have now looked a bit at this 9.f5 continuation also.
(1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Nf3 0-0 6.Bd3 Na6 7.0-0 c5 8.d5 Rb8 9.f5)

Interesting stuff. I mainly checked the combative response 9...gxf5!?

Here is a PGN with some analysis:

Hello.
I was thinking of including this line in my black repertoire as an alternative to 6…Nc6.

1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Nf3 0-0 6.Bd3 Na6 7.0-0 c5 8.d5 Rb8

I’ve read up a bit using Vigus’s books “the Pirc in Black and White” and “Chess Developments the Pirc”. I also have Moskalenkos The Perfect Pirc-Modern and Khalifman on Anand 4. There is a lot to absorb because white has quite many ninth moves and play in almost all continuations is complex. I thought 9.f5 looked decidedly most dangerous and difficult for black though which brings me to my first question.

How is the theoretical status of this line today, some years after it was last covered in literature?
(1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Nf3 0-0 6.Bd3 Na6 7.0-0 c5 8.d5 Rb8 9.f5)


Another thing I wondered was if in the line:
(1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 5.Nf3 0-0 6.Bd3 Na6 7.0-0 c5 8.d5 Rb8 9.Qe2)

Anyone has analyzed the continuation 9…Bg4?

Other continuations after 9.Qe2 look unappealing to me; this is why I ask.
