Pirc Defense
Also known as: Pirc Defence
The Pirc Defense, 1.e4 d6 2.d4 Nf6 3.Nc3 g6, is a hypermodern system in which Black cedes the centre to attack it later. The bishop on g7 and timely breaks with ...e5 or ...c5 give Black flexible, counterattacking play.

Strategic ideas
The Pirc Defense is a hypermodern system in which Black allows White a broad pawn centre and prepares to challenge it from a distance. After 1.e4 d6 2.d4 Nf6 3.Nc3 g6 Black fianchettoes the king's bishop to g7, aiming it along the long diagonal at White's centre and queenside. Rather than staking a claim in the centre with pawns, Black develops flexibly and waits to strike back with the freeing breaks ...e5 or ...c5.
This approach cedes space in return for a resilient, elastic position with many piece-play possibilities. Black typically castles kingside early and keeps options open, choosing the moment and the manner of the central counter based on White's setup. The trade-off is that if Black delays too long, White's space advantage can grow into a dangerous initiative.
Main variations
White's most aggressive try is the Austrian Attack with f4, building an imposing pawn front of e4, d4 and f4 and often castling kingside with attacking intentions. The Classical System with Nf3 is more restrained, developing naturally and keeping a healthy space edge. The 150 Attack, featuring Be3, Qd2 and f3 with ideas of Bh6 and a kingside pawn storm, has become a popular and direct way to challenge the Pirc.
Against each setup Black relies on the same toolkit: complete the fianchetto, castle, and time the ...e5 or ...c5 break to contest the centre. The choice between these breaks depends on White's structure; ...e5 challenges the d4 pawn head-on, while ...c5 pressures d4 from the side and can open the c-file for counterplay.
