@Lizard1
I enjoy your annotations because they are so instructive. They explain the position perfectly and clearly. Thank you.
Bxf6 is truly remarkable. I would never have thought of it.
Black set up is not good, in this line there must be a black pawn watching to the "d5" square, typically by pushing ...c6 or even ...Be6, Bxe6 fxe6. Letting a white knight coming to d5 leaves black too passive...
Maybe I'm wrong, but for me the idea of Bxf6 makes sense only because black doesn't have 13... 0-0 which would solve all his problems. Later he could move Rfe8 instead of Nd7. Truly the problem of e5's Pirc.
no Black rarely castles in the e5 system Sicillian67 is right that black didn't guard d5
