Sicilian Defence, Najdorf Variation

[edit | edit source]

Moves:1.e4 c5 2.Nf3 d6 3.d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6.Bg5 e6 7.f4 Be7

This used to be the main line, mostly out of Fischer's theoretical work. Today it is considered the sharpest line, with sacrifices on d5, b2, g7, and f7, and other such things. Mostly it is because of the large mass of variations that stem from this position. Today, however, the variation has rather fallen out of favor due to the increasing popularity of the Poisoned Pawn Variation after 7...Qb6.
