The Pirc Defence: 1.e4 d6 2.d4... Bg7 arises after 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.f4 Bg7 and falls under ECO code B09. This is the standard developing move for Black, completing the fianchetto and directing the bishop toward White's expanding center. White's central pawn mass represents an increasing positional threat, and a push with e5 would effectively neutralize the fianchettoed bishop's activity. Black is currently safe from this advance for tactical reasons, but as White prepares and coordinates pieces, Black will need to take concrete steps to restrain e5. With 2.5 million Lichess games across all rating levels, it is a specialized opening choice.
