Sicilian Defense: Najdorf, Poisoned Pawn
Main Line
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qb6
Overview
One of the most theoretically dense lines in chess. After 8.Qd2 Qxb2 9.Rb1 Qa3, Black grabs the b2-pawn and accepts a massive White lead in development in exchange for a permanent extra pawn and the bishop pair. Bobby Fischer's signature weapon — he played it in his 1972 world championship match against Boris Spassky, scoring a critical win in game 11. Memorize 25+ moves of computer-checked theory or get crushed in 20 moves — there is no middle ground. Modern engines now consider the line objectively fine for Black with precise play.
