cxd4 7. Qf3 Nh6 8. Ne2 0-0 9. d3 d6. 9. ... Ng4! 10. Bb3 d6 11. 0-0 а5 12. а4 Nе5 13. Qg3 Nd7 14. Qh4 Nc5 15. Bg5 Rе8 is possibly Black’s best defence, Najer – Tiviakov, 37th International Chess Tournament, Groningen 1999.
10. Qg3 Kh8?! 10. ... Ng4 was still worth considering: 11. 0-0 Ne5 12. Bb3 Nd7 (12. ... a5! 13. a4 Nd7 14. f4 Nc5 is a substantial improvement, Borsuk – Azarov, 74th Belarusian Chess Championship, Minsk 2008) 13. f4 Nc5 14. f5 Nxb3 15. cxb3! Qa5 16.

11. h4! f6 12. h5 g5 13. f4. Here 侯逸凡 (Hóu Yìfán) has probably let slip most of her advantage: after 13. Nxd4! f5 14. c3 Qc7 15. Bxg5 fxe4 16. 0-0 White would stand much better.
