Sicilian Defence Najdorf Poison Pawn Variation: New Annotated Chess Opening with Computer Practice on

I have added an annotated opening for the Sicilian Defence Najdorf Poison Pawn Variation with computer practice and Grandmaster examples on the main site at

The Poisoned Pawn Variation is a name used to describe several chess opening variations where a pawn is said to be 'poisoned' because its capture can result in positional problems or material loss for the captor.

The best-known of these, and that most often described as the "Poisoned Pawn Variation," is a line of the Sicilian Defense, Najdorf Variation that begins with the moves:

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Qb6 after which 8. Qd2 Qxb2 usually follows, accepting the 'poisoned' b2 pawn, although White can also play 8. Nb3, protecting the pawn.
