Ba7 has been more fashionable recently. } 9... Nbd7?! (9... e5 { is probably necessary, transposing into a Najdorf where Black is lagging in development, but where perhaps White did not want to commit to f2-f4 just yet. }) 10. g4 h6 11. Qf3 { What can Black do? } 11... g5?! { A thematic break, but Black is too underdeveloped here to make use of it. } (11... Qc7 12. Qh3 { is a powerful idea. }) 12. e5! dxe5 13. fxg5 { Only now, when Black's pawn on e5 prevents ... Nd7-e5! } 13... hxg5 14. O-O-O (14. Rf1 { is even more accurate, according to the engine. }) 14... Rg8 15. Rhf1 Rg7 16. h4 Ng8 (16... gxh4 { was necessary, as the g-pawn may prove to be a target. } 17. g5 Nd5 18. Nxd5 (18. Ne4?? Nxe3 19. Qxe3 Bxg5 20. Nxg5 Qxg5 { was Black's point, where suddenly the king is safe and the extra pawns are decisive. }) 18... exd5 19. g6 Nf6 20. gxf7+ Kxf7 $16 { when, okay, at least Black has a center. }) 17. Ne4 gxh4 18. g5 { Without the resource of ... Nf6-d5, Black is dead in the water. } 18... Qc7 19. Qh5 Bf8 20. Rxf7 { Black has seen enough. } 1-0
