祝融夫人 (Lady Zhùróng)


Last Sunday, China National Space Administration has released footage recorded by its 天问一号 (Tiānwèn-1) Mars probe. The videos and photos taken by the camera installed on the 祝融 (Zhùróng) rover of the 天问一号 (Tiānwèn-1) spacecraft show the lander deploying a parachute before touching down on the surface of Mars and the rover driving away from its landing platform.

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. b3!? Dernier cri.
6. ... e6 7. Bb2 Be7 8. Qd2 Qc7. Also interesting is 8. ... b5 9. f3 0-0 10. a4 b4 11. Nd1 a5 12. Ne3 Bb7 13. Rd1 d5 14. e5 Nfd7 15. f4 Nc5 16. Bd3 Nc6 17. 0-0 ½ : ½ Kr. Georgiev – Pintér, Zonal Tournament, Prague 1985) 9. 0-0-0 b5? Asking for trouble.


10. Bxb5+! Almost a classic. Three Pawns and the initative are well worth a piece. 10. ... axb5 11. Ndxb5 Qb6 12. Nxd6+ Bxd6 13. Qxd6 Nc6? Black had nothing better than to exchange Queens.


14. Nd5!+− exd5 15. exd5 Nxd5 16. Rhe1+ Be6 17. Rxd5 Qb7 18. Rc5. Also strong was 18. Bxg7 Rg8 19. Bf6 with decisive threats such as Re1xe6+.
18. ... Ra6?! 18. ... Rc8 is probably a little better — though, of course, after 19. Bxg7 Rg8 20. Bf6 White’s attack continues.
19. Rd1 Qa8 20. Bxg7 Ne7 21. Qd4 Rg8 22. Bf6 Nd5 23. a4 Nxf6 24. Qxf6 Bxb3 25. Rd6 Rxd6 26. Qxd6 Be6 27. Rb5 Qd8


28. Rb8? An impulsive move which throws away all attack. The right way was 28. Qe5! (actually threatening Rb5-b8) 28. ... Kd7 (28. ... Kf8 29. Rb8 Bc8 30. a5 transposes to the game) 29. Rb7+ Kc6 30. Qb5+ Kd6 31. f4!+− with deadly threats.
28. ... Bc8 29. Qe5+ Kf8? But 侯逸凡 (Hóu Yìfán) returns the favour. After 29. ... Kd7! Black is well and alive with nothing to worry about (if 30. Rb5 then 30. ... Qe7).
30. a5 Rxg2 31. Qc5+ Kg7 32. Rxc8 Rg1+ 33. Kb2 Qd1 34. Qf8+ Kg6 35. Rc6+ Kg5 36. Qg7+ Kf5 37. Qxf7+ 1 : 0.

14. Ne4 f6 15. h3!? b6 16. Qa3 a5 17. Bxd5. White is satisfied with winning a (not too valuable) Pawn — 17. Nc3!? Nb4 18. Qb3 was also interesting.
17. ... Nxd5 18. Rxc6 Bb7


19. Re6? A tactical oversight that costs White the Exchange. White had first to play 19. Rd6 Qc7 20. Re6 Nb4 21. Ng3 Bd5 22. Re7 Qc4 23. Rd7 Be6 24. Rb7 Bd5 with a draw by repetition.

11. Na2! Nxc5


12. axb4! A very strong novelty, with which White forces the gain of two Knights for a Rook (and temporarily a Pawn), in fact tormenting his oppenent to the very end. Previous theory gave 12.

23. c4! bxc4 24. Ba4!? 侯逸凡 (Hóu Yìfán) is desperately looking for her first win in the tournament and doesn’t hesitate to take risks to make her goal. Objectively speaking, 24. Naxc4 Nc5 25. Rea3⩲ might have been a better modus operandi.
24. ... Rf8 25. Bc6!? Consistent — and consistently controversial. A safer continuation was, probably, 25. Bxd7 Qxd7 26. Naxc4 Bc8 27. Kh2 f5 with a double-edged, but essentially balanced game.

Nxa5 Nf4 leads to a Knight ending that looks more drawn than won) 26. ... Kxg7 27. Qc7+ Nd7 28. Nf3!? with a definite edge but no forced win. Now, instead, everything comes very easy to Artemiev:
26. Nb3 c4 27. Nd4 Rxg3 28. Qxg3+ Qg6 29. Qd6 Rf7 30. Nf5 Qg5 31. Qe6 Kf8 32. Nd6 1 : 0.

“It was a difficult game for her in the sense that she never had any real counterchances. She was also struggling to stay afloat, and then it’s easy to make mistakes eventually”, Carlsen finally said. Screenshot from the live stream.

Ethereality

In an interview with Prasad Ramasubramanian of The Times of India, four-time Women’s World Chess Champion 侯逸凡 (Hóu Yìfán) talked about her début in the Champions Chess Tour 2021, about her struggle to maintain a good balance between chess and university, and also about the next World Chess Championship match between Carlsen and Nepomniachtchi. A must read, enjoy.
I agree that I haven’t played a lot of major tournaments. In the last few years, I have been busy completing my Masters in public policy. Managing chess with academics has been tough. Once I finished my course at Oxford, I began playing a few tournaments. As a professor at 深圳大学 (Shēnzhèn University), I devote my full time to that and also train in chess whenever there is spare time. The COVID-19 pandemic means that travelling is difficult and so I will feature in online tournaments only. When the situation becomes better and travel bans are lifted, I hope to play in over-the-board events too. [Read more]

我同意我没有参加过很多主要比赛。 在过去的几年里,我一直忙于完成我的公共政策硕士学位。 与学者一起管理国际象棋很困难。 在牛津完成学业后,我就开始参加一些锦标赛。 作为深圳大学的教授,我把我的全部时间都奉献给了它,并且一有空闲时间就会下棋。 COVID-19 大流行意味着旅行很困难,所以我只会参加在线锦标赛。 当情况好转,旅行禁令解除后,我希望也能参加团体赛。【阅读更多】。
