Chess Openings: Part III: King's Indian:Petrosian system

This is my 3rd part of opening repertoire. I voted for a very interesting system which arises from King's Indian defense and it's called as Petrosian system after Armenian grandmaster and world champion. 

White can play 7.0-0 . But in this system white closes the center for a while to rearrange his pieces and only later to give a punch to black's army. 

Black's main options are`

1. 7...Na6 to prepare Nc6 in the next move.

2. 7...c5 which would give positions like in Benoni defense. White can counter here with Bg5!. If black will play 8...h6 , so after 9.Bh4 Ne8 10.Qc1 Kh7 11.h4 f5 15.h5 will give white very comfortable game.

3.7...a5 introduced E.Geller and L.Stein. After 8.Bg5 h6 9.Bh4 Na6 10.0-0 Qe8 11.Ne1 Bd7 12.Nd3 Nh7 13.f3 h5 the position will be equal.

4.7...h6 is a dubious choice from black, and as T. Petrosian recommended after 8.0-0 Nh7 9.g3 f5 10.Nh4 Qe8 11.exf5 gxf5 12.f4! position will be in white's favour.

The main is this 7...Nbd7 8.Bg5 h6 9.Bh4 g5 10.Bg3 Nh5 11.h4...

And I want to show a game of this position where Petrosian played as white and Lev Aronson as black. And if you know "Iron Tigran" was a master against King's Indian.

Thanks for reading!
