e5 is what white wants to play asap. if black prevents that and plays on the queenside or attacks/opens the center black can equalize or even be better
"pirc alert" by "lev alburt" explains black's plans very well. you can find it in pdf format online
I play pirc defense against e4. however I find often in hard situations specially due to kingside attack with agressive bishops.
I'm looking for some concepts and ideas specially for 6th move.
Some played moves:
6th: c6 (I guess this allows queen b6 later on is that the idea?)
6th: Nd7 (do you feel comfortable with that place for your knight?)
6th: b6 (fianchetto on both sides)
6th: c5 (challenging d4 pawn, often white moves d5)
6th: a6, preventing white bishop come down to b5)
BTW what's the role of Black's dark square Bishop in Pirc defense?
Do you try to maintain the king pawn structure formed in first 4 moves, or normally you go pawn storm on king side?
