# Sicilian Defence, Poisoned Pawn Variation

Moves: 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6.Bg5 e6 7.f4 Qb6

Black launches a direct attack on the b2 pawn. White should defend it with 8. Nb3 or leave it to the enemy with 8. Qd2. This variation gained notoriety in the 1960s with Fischer's espousal of the system. His idea was that after grabbing a pawn, he could use his almost flawless technique to neutralize White's dangerous lead in development, and then win with his extra pawn and bishop pair.
