[August 12, 2017] Updated Opening Line by Aleksandar Kovačević:
Sicilian Defense, Najdorf Variation – English Attack with 6… e5 7. Nb3 Be6 8. f3 Be7

[Line 500 : 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Be3 e5 7. Nb3 Be6 8. f3 Be7]

After the usual 9. Qd2 O-O 10. O-O-O, Black has in 10… a5 a fitting alternative to the main 10… Nbd7 (Line 500). In response to 10… a5, White usually chooses one of the following options: 11. a4, 11. Bb5 and 11. Kb1.

White permanently stops the a5-a4 advance with 11. a4, but that comes at a cost of making his King somewhat vulnerable. After 11. a4 Nc6 12. g4 Nb4 13. Kb1 Rc8 Black gets sufficient counterplay thanks to the d6-d5 motive.

By choosing 11. Bb5 White keeps an eye on the a4-square, but Black is often ready to sacrifice his a-pawn for the initiative by playing a5-a4.

The third important option is 11. Kb1, where after 11… a4 12. Nc1 a3 13. b3 Ra5 Black wants to play d6-d5, with mutual play.

[Diagram: Black to Move] White’s poor piece coordination together with the weakened position of his King provide Black with an opportunity to strike a final blow. How can Black develop a decisive attack?
