Sicilian Defense: Najdorf Variation

What Is The Najdorf Variation?

5...a6 takes b5 from White's pieces. Without it, ...e5 runs into Bb5+, or Nb5 hitting the d6 pawn. With a6 in, you hit the centre with ...e5 or ...e6 on your own terms and gain the ...b5 break. a6 is no waiting move, it is what makes the system work.

After ...e5 the d6 pawn is backward and d5 is a hole, so White's play runs through that square: Bxf6 and Nd5. You accept that for the dark squares and a fast queenside. Najdorf games are decided by speed, not material. In the English Attack, 6.Be3, White castles long and storms with f3 and g4 while you race with ...b5-b4; the Poisoned Pawn, 6.Bg5 e6 7.f4 Qb6, has Black grab b2 and defend precisely for the extra pawn.

How Should You Respond To The Sicilian Defense: Najdorf Variation?

There is no main line against the Najdorf, and the spread proves it: 24% choose 6.Bg5, 23% 6.Be3 and 11% 6.Bc4. Black has spent a move on ...a6 without developing anything, which buys the b5 square and takes away every check and jump that square offers you.

...a6 is a move against your pieces rather than a developing move, so punish it by getting your pieces out before Black finishes preparing. 6.Be3 heads for the English Attack with f3, Qd2 and a pawn storm, which is the most direct way to make that tempo count. 6.Bg5 is sharper and far more theoretical. Black scores 49% to 45% across 2,137 games, better than in any other Sicilian branch, so choose one system and know it properly rather than improvising.
