About the Sicilian Najdorf

The Najdorf has been the weapon of choice for Fischer, Kasparov, and many other world champions. The move 5...a6 serves multiple purposes: it prevents Nb5, prepares ...e5 or ...b5, and controls the b5 square. White can respond with the English Attack (6.Be3), the Classical (6.Be2), or the aggressive 6.Bg5. Each leads to completely different types of positions.

Key Ideas

  • 5...a6 is multipurpose — prevents Nb5, prepares b5 and e5
  • The pawn structure is asymmetric — Black gets queenside play
  • ...e5 is the key central break for Black
  • ...b5 expands on the queenside
  • Be ready for sharp tactical battles in every line
