The plan, from masters' games

The Pirc's move order has a reason behind it. comes before the fianchetto because the knight hits e4 at a moment when no White piece defends that pawn. White has to spend the move holding it, usually with 3.. Only then do you play and bring the bishop to g7. That is the plan of 62 of every 100 strong online players and 73 of every 100 over the board; around 18 of every 100 strong online players develop that bishop to e7 instead.

With 4. White puts pawns on d4, e4 and f4 and gets ready to push to e5 and kick your f6 knight. Two pawns already back that push, and only your d6 pawn holds it up. Your does two jobs. It clears f8, which you need in order to castle. And it tucks the bishop behind the knight: while the knight sits on f6 the bishop sees only that square, but as soon as the knight moves, the diagonal opens all the way to e5 and d4. 97 of every 100 strong players choose it.

With 5. White adds a third defender of e5 and a second defender of d4, which until then only the queen covered. You answer : your king leaves the center before the e5 push can open lines, and settles behind the g7 bishop and the pawns on f7, g6 and h7. 72 of every 100 strong players go this way.

At your level that line is rare. After , only 8 of every 100 opponents play 4.. Far more often you will see 4., the Classical Variation, or 4., the Byrne Variation, where the bishop attacks your f6 knight. The plan stays the same: and castle short. Watch for two earlier cases as well. If White answers with 3., e4 is still undefended and wins the pawn. And if White plays 3., hitting your knight, you score 60 of every 100 at your level.
