I faced this opening last year, and I played the same way I did in that game”, 谭中怡 (Tán Zhōngyí) said afterwards. She alludes to 15. Nf4 Nh5 16. Bd3 Nxf4 17. exf4 Kd7 18. Kd2 Rae8 19. b4 Kd6 20.

15. ... Ke7 16. Bh3 Rhg8. 16. ... Rae8 gave raise to a model strategic game: 17. Nf4 Kd6 18. Kd2 Re7 19. a4 a5 20. Ra3 Rhe8 21. Rb3 Kc7 22. Rc1 Kd6 23. Bg2 Nh5 24. Nxd5! cxd5 25. Rb6+ Kd7 26.

22. Rg8 Rxg8 23. Rxg8 Bf3 24. Bf1 Rxh4 25. h3 Re4 26. Ra8 a6 27. Ra7 Re7 28. Kc3?! White undertakes an adventurous King march towards b6, aiming at the Queenside Pawns. Objectively, it might be safer for White to play 28. a4 h5 29. a5 h4 30. Ra8 Kg7 31. Ra7 Kf6= with a likely draw.
28. ... h5 29. Kb4 h4 30. a4. If 30. Kc5 then 30. ... f4! 31. Kb6 fxe3 32. fxe3 Rxe3 33. Rxb7 Re1 34. Bxa6 Bg4!⩱ with the upper hand for Black.


30. ... f4! “Indeed, I wanted to play ... f5-f4 early in the game... But the exact time was after I had played the Bishop to h1 because then I can play ... f4-f3, a strong manoeuvre”, 谭中怡 (Tán Zhōngyí) then argued. “I had to be careful because I would lose if I didn’t play exactly”.

34. Bd3? The losing move. White ought to play 34. Ra7! Bg2 35. Bxa6 Rxe3! 36. Rxb7 Re2! 37. Bd3 Rxf2 38. a6 Bf1 39. a7 Bxd3 40. a8=Q Rc2+ 41. Kd6 f2 42. Rb8 Bh7 43. Qa1 Bd3 44. Qa8 Bh7 with a draw.

“I wanted the game to be competitive, but I didn’t know if she’d accept the unbalanced aspects of the game”, 谭中怡 (Tán Zhōngyí) said eventually. “But it would not be a draw”. Photo: Anna Shtourman/FIDE.
