Qxa6 Rxc2 with slight advantage to Black, Lautier – Movsesian, 7th Sigeman & Co. Chess Tournament, Malmö 1999. 19. ... Nh5. Nerwal: “19. ... Bb5 is certainly possible. It’s not clear how exactly Black is doing after 20. Rb1 (assessed as +/= by Ftacnik) or 20. Ng4, though. Possibly White keeps some initiative”. 20. Qg4 g6 21. Qh3! Well conceived, threatening Nf2-g4. True to her style, Miss 侯逸凡 (Hóu​ Yì​fán) attacks the King, her favorite target! For the more stereotyped 20. Qf3 g6 21. Ng4 f6 22. f5 (or 22.
