Dutch Defence A85

1. d4 f5 2. c4 Nf6 3. Nc3 g6 4. h4! Bayonet attack! 4. ... Bg7. Possibly better was 4. ... d6 5. h5 Nxh5 6. Rxh5! gxh5 7. e4 fxe4 8. Qh5+ Kd7 making the position very double-edged. 5. h5! Nxh5

6. e4! fxe4 7. Rxh5! gxh5 8. Qxh5+ Kf8 9. Bh6! Black’s King is already in danger. 9. ... e6. If 9. ... Bxh6 then 10. Qxh6+ Kg8 11. Qg5+ Kf7 12. Nxe4 Qg8 13. Qf4+ Ke8 14. Qxc7 with a very powerful attack, Nakamura – Barron, PWC Open, Toronto 2009. 10. Nxe4 Qe7. Equally bad is 10. ... d5 11. Bxg7+ Kxg7 12. Qe5+ Kh6 13. Nf6 and White wins, Turov – Sabirova, Tashkent 2012. 11. Bxg7+. Even stronger might be 11. 0-0-0! Bxh6+ (if 11. ... Qf7 there follows 12. Bxg7+ Qxg7 13. Rd3 Nc6 14. Rg3 and wins) 12. Qxh6+ Qg7 (12. ... Ke8 13. Rd3 Rf8 14. Rg3) 13. Qf4+ Qf7 14. Qxc7 d5 15. Qd8+ Kg7 16. Qg5+ Kf8 17. Nd6 and wins, Valles – Frederic, Le Grand-Bornand 2007. 11. ... Kxg7 12. 0-0-0 d6 13. Rd3 Rf8 14.

Qg6. Threatening Ng5-f7+. 18. ... Rxg5 19. Qxg5 Qg7 20. Bd3? Hardly inspired and certainly not best. 20. Qh4! e5 21. dxe5 dxe5 22. Nxe5 was the clearest way for White to win. 20. ... Bd7? Black’s only chance was 20. ... e5, although after 21. dxe5 dxe5 22. Qxg7+ Kxg7 23. Nxe5 h5 24. f3 White will emerge a clear Pawn ahead in a very advantageous position. 21. Qxg7+ Kxg7 22. g5 1 : 0.

袁元凌 (Yuán Yuánlíng) – Mariya Muzychuk
Women’s World Chess Championship; Krasnaya Polyana, March 17, 2015
Caro-Kann Defence B15

Yesterday Grandmaster Kevin Spraggett wrote: “Canada is fortunate to have youngster Yuán Yuánlíng (born 1994) represent its colours. The super-busy Yale undergraduate has recently come back to active chess after a 2 and a half year absence between January 2011 and the summer of 2013. She scored an excellent 7½ points at the Tromsø Olympiad in 2014, and has played in several tournaments already this year as a warm up for Sochi. Yuán’s first round opponent in the knockout event is the Ukrainian Mariya Muzychuk, one of the top females in the world, and sister of world number three Anna Muzychuk. I am certain that all of my readers wish her the best of success in Sochi!”.
