Luckier against 2233 – or tougher?

Hi everyone! Thank you for you kind comments on a recent game where I crushed a stronger guy in the PIrc.

This time, there is another big fish that got caught in my net. But why is it again the Austrian Attack? No idea. Let's see at which stages Black rushed it a bit. (Not something to do in such a complex opening!)

1. e4 d6 2. d4 g6 3. Nc3 Nf6 4. f4 Bg7 5. Nf3 c5

One of the two popular moves in this position. Black strikes at White's center immediately, so I need to know a good response.

6. Bb5+ Bd7 7. Bxd7+ This capture actually simplifies the position and helps Black develop at their leisure. Black chooses to unleash their g7 bishop.
7...Nfxd7 8. O-O O-O 9. Kh1

Should have pushed with d4-d5 in the last few moves. It does not seem to be good to allow Black to take on d4, as Black gets a target to attack with ...Nc6 and ...Qb6.

9...cxd4 10. Nxd4 Qb6 11. Nf3?! Retreating. In fact, 11. Be3 would be quite playable, as 11...Qxb2 would be met by 12. Nd5! targeting c7 and e7 – at least winning the pawn back. A good idea to remember for the future!
11...Nc6

We are getting into a tense middlegame. In the Austrian Attack, the key point is that Black's kingside may end up under a massive assault with f4-f5, so Black must watch out.

12. Nd5 Qd8 13. c3 Playing it safe on the queenside, but the Pirc is not about that.
13...e6 14. Ne3 Nc5 15. Qc2 b5

Black's intentions are clear: to pressurize c3 and create targets for attack. In response, we are launching it against Black's king. Let's see if they can handle it.

16. f5 Rc8 17. a3 a5 18. Ng4

Things are getting hot over there. Now Black should hold on under pressure and respond with 18...Nxe4!, utilizing the fork after 19. Qxe4 exf5 to win their piece back.

18...exf5 Black snaps and helps me open the lines towards their king.
19. exf5 h5?

Even without any calculation, you can see this is weakening the exact area where White is attacking. The g6 pawn, for example, is now there for the taking.

20. Nh6+ Kh7 Walking right into the following check. 21. Ng5+

21...Kh8 1-0 Black resigned without waiting for my deep thought about which knight to use on f7 first. It turns out either is good! Black will likely reply with ...Rxf7 and then (the other) Nxf7 will follow, winning the queen. However, the added nuance is 22. Ngxf7+! would force Black to take with the rook, as if Black retreats with 22...Kh7 then 23. fxg6#! This spectacular checkmate deserves a diagram:

It's a pity this did not happen in the game, but still. Woohoo! Here is the full analysis of this game and my other games against the Pirc.

Did Black rush by moving too quickly? Anyway, openings like the Pirc do not tolerate any rush. I do realize though that there is a lot more tactics to learn and master. And you? What would be your conclusions after such a game?
