Is pirc defense still reliable?

the pirc is used even by Super GM's to fight for a win.
all respectable defenses equalize. Some just take longer than others.
in fact, the main drawback of the pirc is that black has to do most of the heavy theory since white has so many different ways to at keep a small advantage to equalize whereas black has to play in narrow corridors. But there is nothing "weak" about it. All the secondary defenses (scandinavian, pirc/modern, alekhine, Nimzowitsch, Owen )  are playable at all levels, but a big reason for their inferiority in top level games is that they lack the flexibility of the big 3 or the solidity of the Caro Kahn.

dark   guess I disagree with you,

Take for example the scandinavian. I have won many games with Black with this opening up to and including grandmaster. Also wrote a book on that opening. And my games are in books on the scandinavian played later than my book. If you learn and know a particular opening  at a high level you learn the good lines Against that opening. Now I know how to play against that opening and think White has very strong lines which might even refute that opening?

What I know about the Pirc is White has very strong lines against it  When these lines are known [and they will be known] Black will be sorry he ever played the Pirc as one of his main defenses to 1. e4

The Pirc is still reliable. It just takes more work to equalize than others as dark has said, since white can play almost any reasonable setup and keeps small edge.

I've also experimented a lot (against Shredder) with 4. Be2 which has a lot of move order possibilities, and still leaves open Be3 Qd2 or immediately h4 or classical. But I think it is still a close to equal and hard fought game.  Maybe there is a line where white can force an endgame with a slight advantage, but many openings have that [and it's really less fun to go there right away].

not really, i won a pirc player just in 17 moves, in the way people crush sicilian dragon:

Ya, that is what i thought in the beginning

it is a right sentence, it does leave some weaknesses, but you get them right in one move or two

Well, I doubt that! The guy doesn't know Petroff, Berlin and stuff ya... probably

Ridiculous. 

Here is one line---I can't go further as am playing in a vote chess game which started this way,  We are way past this move however.

the loewenthal gives black GREAT chances in low time controls

Aha, now that is something i was looking for
