Pirc

Pirc is a chess opening characterized by the moves 1. e4 d6 2. d4 Nf6 3. Nc3 g6. It is a hypermodern opening, meaning that Black allows White to establish a pawn center, intending to challenge it later with pieces. The name "Pirc" comes from the Yugoslavian chess master Vasja Pirc.

The Pirc Defense is a flexible system that can transpose into various other openings depending on White's response. Common continuations for White include the Classical Variation (4. Nf3 Bg7 5. Be2 O-O 6. O-O), the Austrian Attack (4. f4), and systems involving g3. Black's main goals are to control the center from a distance, develop pieces harmoniously, and often launch a kingside attack.

While not as popular as some other defenses, the Pirc remains a viable option at all levels of play. It can lead to complex and unbalanced positions, offering players opportunities for active counterplay. Its strategic richness and the potential for surprise make it an attractive choice for those seeking to avoid mainstream theory. Black aims for a solid pawn structure and seeks to exploit any overextension by White.
