The Pirc Defense arises after 1.e4 d6 2.d4 Nf6 and falls under ECO code B07. Black develops the knight while putting pressure on e4, entering the main line of the Pirc Defence. White has multiple ways to protect the e-pawn, with 3. Nc3 being the most popular. Black typically continues with 3...g6 and 4...Bg7, fianchettoing the bishop and preparing to castle. Since Black's development is relatively slow, White has the opportunity to seize additional space, particularly on the kingside with 4. f4, the Austrian Attack (followed by Nf3), which clamps down on e5 and prevents Black's key freeing move ...e5. If Black tries 3...e5 instead, 4. Nf3 transposes into a Nimzowitsch Philidor. The Lion's Jaw, 3. f3, is another way to defend e4 while preserving the option of c4 for further expansion. After 3...g6 4. c4 Bg7 5. Nc3, the position transposes into a Samisch King's Indian. This setup also permits 3...e5, though 4. dxe5 leads to a queen exchange (4...dxe5 5. Qxd8+ Kxd8 6. Bc4 Ke8), making 4. d5 a preferable response. The quieter 3. Bd3 or 3. Nd2 are occasional alternatives that defend e4 without blocking the c-pawn. With 27.2 million Lichess games across all rating levels, it is a well-established opening choice.
