神州行 (Easyown)

Valentina Evgenyevna Gunina – 居文君 (Jū Wénjūn)
14th “映美杯” (“Yìngměi Cup”) Chinese Chess League; 南京 (Nánjīng), May 23, 2018
Russian Defence C42

1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. c4 Be7 6. d3!? Nf6 7. d4 0-0. Or 7. ... d5 at once, transposing into the Exchange Variation of the French Defence. 8. Nc3 d5. Just the same. 9. Bd3 dxc4 10. Bxc4 Nc6!? Better is 10. ... Bd6! 11. h3 h6! 12. a3 Bf5 with a very comfortable game for Black, de la Bourdonnais – MacDonnell, London 1834, match game 44. 11. h3 Na5 12. Bd3 Be6 13. 0-0 h6 14. Re1 c5 15. Bc2 Nc6 16. Be3 Qa5? A big tactical error that loses the Exchange for no good reason. 16. ... b6 looked like nothing special for White. 17. d5! Rfd8 18. Bd2! The pointe. 18. ... Nxd5 19. Nxd5 Rxd5 20. Bxa5 Rxd1 21. Raxd1 Nxa5 22. Be4 Bf6 23. b3 c4 24. bxc4 Bxc4 25. Bd5 Rc8 26. Bxc4 Nxc4 27. Rd7 Rb8 28. Rc1 Nb6 29. Rd3 g6 30. Nd2 Kf8 31. Ne4 Be7 32. Nc5 Rc8 33. Rdc3 Rb8 34. Kf1 Ke8 35. Ne4 h5 36. Rd1 Kf8 37. Rdd3 Ke8 38. Rc7 Na8 39. Rc2 Nb6 40. Ke2 Kf8 41. Kf3 Ke8 42. g3 Kf8 43. h4 Kg7 44. Rd4 Kf8 45. Ng5 Nc8 46. Rcd2 Nb6 47. a4 Rc8 48. Kg2 Rc5 49. f4 Rc7 50. Kh3 a5 51. Rb2. Stockfish evaluates 51. f5! gxf5 52. Rf2 Bc5 53. Rxf5 Bxd4 54. Ne6+ Ke7 55. Nxc7 Nxa4 56. Rxa5 as a much better winning path for White. That said, it’s true that Gunina delays too much in mobilising her Pawn majority on the Kingside. 51. ... Bb4 52. Rd8+ Ke7 53. Rg8 Nxa4. Now, Black’s two passed united Pawns on the Queenside become telling, and finally, after much striving, 居文君 (Jū Wénjūn) can claim a compensation. 54. Re2+? This only helps Black in her long march towards the promised land. Much better was 54. Rf2 soonly followed by f4-f5. 54. ... Kd6 55. Rg7 Nc3 56. Re5 Nd5 57. Rg8 Kc6 58. Rd8 Nc3 59. f5 Kb6


60. Ra8. 60. Nxf7! gxf5! 61. Rxf5 a4∞ was quite unclear, but probably less dispersive than the text. 60. ... a4 61. g4? White was still in time for 61. Nxf7(!). Gunina’s continuous losses of time ended up putting her into a lost position. 61. ... a3 62. Nxf7? Now this is objectively wrong, but at least succeeds in unbalancing 居文君 (Jū Wénjūn). Anyway, other moves would not have probably prevented Black from making gradual progress towards a win. 62. ... hxg4+? This zwischenzug check turns out to be a cruel fata morgana. Simply 62. ... Rxf7! 63. fxg6 Rf8 would have lead to an easy win. 63. Kxg4 gxf5+. Now, if 63. ... Rxf7 64. fxg6 Rf8 then 65. Rea5! Bxa5 (with the King on h3, Black could give a deadly check at f3: ... Rf8-f3+) 66. Rxf8 a2 67. Rf1 Nb1 69. g7 with a likely draw. 64. Rxf5 a2 65. h5 Rc8 66. Rf6+ Kc7 67. Ra7 Kb8 68. Rxa2 Nxa2 69. h6 Bc3 70. Rg6 Rc4+ 71. Kh3 Rc5 72. Nd6 Bd2 73. Kg4 Bxh6 74. Rxh6 Rc6 75. Kf5 Nc3 76. Ke5 Ka7 77. Rh7 Rc5+ 78. Ke6 Nb5 79. Rxb7+ Ka6 80. Rxb5 ½ : ½.

The Queen’s Pawn

居文君 (Jū Wénjūn) – Olga Alexandrovna Girya
 14th “映美杯” (“Yìngměi Cup”) Chinese Chess League; 南京 (Nánjīng), May 22, 2018
Semi-Slav Defence D44

Just say bye-bye to the crown and the royal limousine. 上海 (Shànghǎi)’s Queen, 居文君 (Jū Wénjūn), has already got back to her (hard) daily work in the backwards of the Celestial Empire! 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. Nc3 e6 5. Bg5 dxc4 6. e4 b5 7. e5 h6 8. Bh4 g5 9. Nxg5 hxg5 10. Bxg5 Be7 11. exf6 Bxf6 12. Bxf6 Qxf6 13. g3 Na6 14. Bg2 Bb7 15. Ne4. If 15. Nxb5 then 15. ... 0-0-0 16. Qa4 cxb5 17. Bxb7+ Kxb7 18. Qxb5+ Ka8 19. Qc6+ Kb8 20. Qb5+ Ka8 21. Qc6+ Kb8 22. Qb5+ Ka8 ½ : ½ Obolentseva – Girya, Russian Women’s Cup Final 2016, Khanty-Mansiysk 2016. 15. ... Qe7 16. 0-0 0-0-0 17. h4. The alternative was 17. a4 Kb8 (Kasparov then suggested 17. ... f5! 18. axb5 cxb5 19. Rxa6 Bxa6 20. Nc5 Qxc5! 21. dxc5 Rxd1 22. Rxd1 b4!∞) 18. Qd2 b4 19. Rac1 e5 20. Rxc4 f5 21. Ng5 c5 22. Bxb7 Qxb7 23. Qe3 exd4 24. Qe5+ Ka8 25. Ne6 (Alexander Valeryevich Khalifman recommended 25. Qxf5±) 25. ... Qh7 26. h4 Rhe8 27. Qe2 Rd6 28. Qf3+ Qb7 29. Qxb7+ Kxb7 30. Nxc5+ Nxc5 31. Rxc5 d3 32. Rd1 Re2 33. Rb5+ Ka6 34. Rxb4 d2 35. Kf1 Rde6 36. Kg2 Rd6 ½ : ½ Kasparov – Smyslov, Candidates Final, Vilnius 1984, match game 5. 17. ... c5 18. a4 Rxd4 19. Qe2 b4 20. Rad1 Qc7 21. Ng5! This seems stronger than 21. Rc1 which yet gave White the win, but only after many complications that Black might have handled better: 21. ... Bd5 22. Nf6 Bxg2 23. Kxg2 e5 24. Ng4 Qb7+ 25. Kh2 f5 26. Qxe5 Qh7 27. Qf6 Rxg4 28. Qxa6+ Kb8 29. Qf6 f4 30. Rfd1 fxg3+ 31. fxg3 Rc8 32. Kh3 Qe4 33. Rd8 Rg8 34. Qd6+ Ka8 35. Qd5+ Qxd5 36. Rxd5 Rgd8 37. Rxd8 Rxd8 38. Rxc4 Rd5 39. Kg4 Kb7 40. h5 Kc6 41. h6 1 : 0 Matlakov – Sandipan, 15th Aeroflot Open, Moscow 2017. 21. ... Bxg2 22. Kxg2 Rhd8 23. Rc1 R8d7 24. Rxc4 Qc6+ 25. Kg1 Rxc4. Probably Black may improve her game somewhere, but it’s not quite so easy to guess how and where. From a human viewpoint, the text makes little sense, as any kind of simplification ends up enhancing the strength of White’s passed h-Pawn. So 25. ... Rd2 appears to be a more lively choice, and it is likely worth further analysis. 26. Qxc4 Nc7. Not 26. ... Qxa4? because of 27. h5 with a win coming soon. 27. Rc1 f5 28. h5 e5 29. Qg8+ Kb7 30. Qg6. Stockfish evaluates 30. Qf8(!) f4!? 31. Qf5 as a more convincing win for White. 居文君 (Jū Wénjūn), however, is eager to make things simpler, even at the cost of renouncing something. 30. ... Qxg6 31. hxg6


31. ... Kb6? Black ought to have played 31. ... Rg7 32. Rxc5 Rxg6 33. Nf7 Ra6 34. a5 which leaves White with much the better game (and possibly an almost won game) that, however, would still have to be won. 32. Nf7 e4? This loses off right, but also 32. ... Ne6 33. Nxe5 Rg7 34. f4 is undefendable. 33. g7 1 : 0.

Google Save the Queen

杜雨馨 (Dù Yǔxīn) – 谭中怡 (Tán Zhōngyí)
13rd “映美杯” (“Yìngměi Cup”) Chinese Chess League; 中山 (Zhōngshān), December 3, 2017
Spanish Game C77

1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. d3 Bc5 6. 0-0 d6 7. c3 Ba7 8. Bg5 h6 9. Bh4 Bd7 10. Nbd2 Qe7 11. Re1 g5! 12. Bg3 0-0-0! The heterogeneous castling means that Black is running to win. 13. b4 h5 14. h4 g4 15. Ng5


15. ... Ng8! Something went wrong with White’s opening as Black seized the initiative. Now the g5-Knight is in trouble. 16. d4? Amateurly speaking this is not a solution. White ought to play 16. Bxc6 Bxc6 17. Qb3. 16. ... f6 17. Ne6 Qxe6. Perhaps 谭中怡 (Tán Zhōngyí) could play for winning a piece by 17. ... Bxe6 (and if 18. d5 then 18. ... f5!), but she must have feared some kind of tricky attack against her own King. Whatever it is, her decision sounds quite good. 18. d5 Qe8 19. dxc6 Bxc6 20. Bxc6 Qxc6. Black contented herself with an extra Pawn and a much better position. 16th Women’s World Chess Champion has no difficulty in bringing home the point, which will give 重庆 (Chóngqìng) the team’s win over 深圳 (Shēnzhèn). 21. c4 Ne7 22. Qb3 Bd4 23. b5 Qb6 24. Rab1 c5 25. bxa6 Qxa6 26. Qb5 Kc7 27. Rb3 Ra8 28. Reb1 Qxb5 29. Rxb5 Rhb8 30. Nb3 Nc6 31. Nxd4 Nxd4 32. R5b2 Ra4 33. Rc1 Rba8 34. Rcb1 R8a7 0 : 1.

Nemo propheta in patria

Mariya Olehivna Muzychuk – 张岚琳 (Zhāng Lánlín)
13rd “映美杯” (“Yìngměi Cup”) Chinese Chess League; 中山 (Zhōngshān), December 2, 2017
Semi-Slav Defence D46

After a long strike, due to a dispute with the Ministry of Youth and Sports of Ukraine, former Women’s World Chess Champion Mariya Olehivna Muzychuk came finally back to the board, but not to represent her country. Both she and her sister are actually playing in the Chinese Chess League: Mariya Olehivna for the 河北 (Héběi) team, and Anna Olehivna for the 上海 (Shànghǎi) team. 1. d4 d5 2. c4 c6 3. Nf3 Nf6 4. e3 e6 5. Bd3 Nbd7 6. 0-0 Bd6 7. Nc3 0-0 8. e4 dxe4. The alternative is 8. ... dxc4 “transposing” into a Slav formation. 9. Nxe4 Nxe4 10. Bxe4 Nf6. This pseudo-gain of time doesn’t enjoy a good (theoretical) reputation. Both 10. ... c5 (11. Bc2 Qc7 12. Qd3 f5) and 10. ... h6 (11. Bc2 e5 12. Qd3 f5) are regarded as sounder. 11. Bc2 h6. Not 11. ... c5? because of 12. Bg5 (intending Qd1-d3) 12. ... cxd4 13. Qxd4 Be7 14. Qh4! h6 15. Bxh6! with overwhelming attack, Jaffe – Baird, New York 1911. 12. Ne5!? Probably a new move. In any event the old one is still very good: 12. Be3! Re8? 13. Qd3 Qc7 14. c5 Bf8 15. Ne5 with great advantage to White, Pillsbury – Winawer, Budapest 1896. 12. ... c5 13. Bf4 Qb6? A serious mistake that costs Black the Exchange for no compensation at all. She should have taken on d4.


14. b4! What follows is all forced: 14. ... Qxb4 15. Nd3 Qb6 16. dxc5 Bxc5 17. Rb1 Qc6 18. Nxc5 Qxc5 19. Bd6 Qh5 20. Bxf8 Qxd1 21. Bxd1 Kxf8 22. Bf3. The ending is hopeless for Black. 22. ... Rb8 23. c5 b6 24. cxb6 axb6 25. Rb4 e5 26. Re1 Be6 27. a4 Nd7 28. Bc6 Rc8 29. Bb5 Rc5 30. f4 f6 31. Rd1 Ke7 32. Bxd7 Bxd7 33. fxe5 Rxe5 34. Rxb6 Bxa4 35. Rb7+ Kf8 36. Ra1 Be8 37. Raa7 Rg5 38. Kf2 h5 39. g3 Kg8 40. h4 Rg4 41. Rb8 Kf8 42. Kf3 f5 43. Ra5 g6 44. Re5 1 : 0.

居文君 (Jū Wénjūn) – 李超 (Lǐ Chāo)
13rd Chinese Chess League; 北京 (Běijīng), June 11, 2017
Queen’s Indian Accelerated A50

1. d4 Nf6 2. c4 b6 3. Nc3 Bb7 4. f3 d5 5. cxd5 Nxd5 6. e4 Nxc3 7. bxc3 e5 8. Be3 Be7? It looks like an improvised Pawn sacrifice in a well-known position. For 8. ... exd4 9. cxd4 Bb4+ 10. Kf2 0-0 11. Bc4 see Riumin – Chekhover, Leningrad 1934. 9. dxe5 Nd7 10. Qa4 c6 11. Rd1 b5 12. Qb3 Qa5 13. f4 0-0-0 14. Nf3 Nc5 15. Bxc5 Bxc5 16. Bd3 Rd7 17. Ke2 Rhd8 18. Rhf1. 18. e6 fxe6 19. Ng5 was also very interesting. 18. ... h6 19. f5! Qc7 20. g3! a5 21. a4! 李超 (Lǐ Chāo) ended up getting completely outplayed by his opponent. 21. ... bxa4 22. Qxa4 Qb6


23. Qc2? 居文君 (Jū Wénjūn) hesitates in the moment of truth, throwing all her advantage away. The trivial 23. Rb1 Rxd3! 24. Rxb6 Bxb6 25. Rb1 Re3+ 26. Kf1! Rxf3+ 27. Kg2 Rf2+ 28. Kh3 Be3 might have given Black an easier – if not better – game, but 23. e6! seemed to put insurmountable problems to Black; for instance: 23. ... fxe6 24. fxe6 Rd6 (or 24. ... Re7 25. Rb1 Qa7 26. Bc4 followed by Nf3-e5 with devastating effect) 25. e7 Re8 26. Rb1 Qa7 27. Nd4! Kc7 (or 27. ... Bxd4 28. Rf8 Kd7 29. cxd4 Rxe7? 30. e5+−) 28. Nf5 with a (likely significant) gain of material. 23. ... Ba6! Well, the rest is quite uninteresting. White’s position still might be drawable, but 居文君 (Jū Wénjūn) has no longer the will to hold it, and slowly her opponent succeeded in picking the whole point. 24. Bxa6+ Qxa6+ 25. c4 a4 26. Rxd7 Rxd7 27. Ra1 a3 28. Ra2 Rb7 29. e6 fxe6 30. fxe6 Re7 31. e5 Rxe6 32. Kf1 Re7 33. Kg2 Kc7 34. Ra1 Qa5 35. Qd3 Rd7 36. Qc2 Bb4 37. Ra2 Bc3 38. Qe4 Bb2 39. e6 Re7 40. Qf4+ Kb7 41. Nd4 Qb4 42.

Db3 h6!? 马群 (Mǎ Qún)’s novelty actually appears to be better on 13. ... Be7 14. Ne5 0-0 15. 0-0 Nd7 16. Bxe7 Qxe7 17. Nxc6 bxc6 18. Na4 Rab8 19. Qc3 Rfc8 20. Rac1 h5 21. b3 h4 22. h3 Rb5 23.

Consistent with his 13th move and well calculated. White has no real way to exploit the weakening of Black’s Kingside, and indeed she will have to play with mood and tone for keeping a sound balance. 18. dxe5


18. ... g5 19. Bg3 Ne4 20. Qd1 Kg7 21. f4 Bb5 22. Re1 Nxc3 23. Rxc3 Rxc3 24. bxc3 f5 25. exf6+ Qxf6 26. fxg5 hxg5 27. Qd4 Qxd4 28. exd4 g4 29. Be5+ Kg6 30. Bd6 Re8 31.

26. Qb3? This is the beginning of all White’s trouble. White’s best consisted in 26. Ne2! Qxd3 27. Bxd3 Ra7 28. Ra2 Rea8 29. Rfa1 g6 with a rough equality. 26. ... Rec8 27. Ra2 Rc4 28. Ne2 Qe3.

35. ... Qxf4. Of course there’s nothing wrong with this, but also 35. ... Rc2!! would have forced checkmate in a few moves. 36. Rf1 (36. gxh3 Bxg1−+) 36. ... Qe3 37. Raf2 (37. gxh3 Rc1−+) 37. ... Rc1 38. Qb3 Qxf2! 0 : 1.
