The Pirc Defense are underrated?

1. THE OPENING.
The Pirc Defense is a exotic opening and involves a game with 1.e4 d6. The black will play the structure of the King's Indian Defense, with the fianchetto g6 and Bg7 and with Cf6.
2. HOW WHITE PLAY?
If you look in the analysis, the lichess engine consider 1...d6 a mistake and gives the advantage for white, but... How white can take advantage of it? Its simple. The best way for white play is taking the center and leaving the pieces stuck in the development.
3. WHY THIS INS'T "BAD"?
Incredibly, even after the white getting the advantage, the black can get a counter-game, but for this you need to know the theory of the opening and his variants.
4. CONCLUSION.
The Pirc Defense ins't too bad, but for high level chess is a little weak. I recommend you play If you like only in the rating 1200-1800.

THANKS FOR THE ATTENTION.
