日正當中 (High Noon)

Fabiano Caruana – 王皓 (Wáng Hào)
1st Online Nations Cup; India – China (25+10); chess.com, May 9, 2020
Russian Defence C42

By virtue of its half a point difference over Europe, United States will face China in tomorrow’s final. Fabiano Caruana has much merit, having scored, so far, 6½ points out of 8. 1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nf3 Nxe4 5. Nc3 Nxc3 6. dxc3 Be7 7. Be3 0-0 8. Qd2 Nd7 9. 0-0-0 Nf6 10. Bd3 c5 11. Rhe1 Be6 12. Bf4. Varying from their game at the recent Candidates (half)-Tournament: 12. Kb1 Qa5 13. c4 Qxd2 14. Nxd2 Rad8 15. f3 b6 16. g4 d5 17. g5 Nh5 18. cxd5 Bxd5 19. Ne4 f5 20. gxf6 Nxf6 21. Bg5 Kf7 22. Ng3 c4 23. Bf1 b5 24. a4 a6 25. axb5 axb5 26. Nf5 Bc5 27. Re5 Bxf3 28. Rxd8 Rxd8 29. Rxc5 Rd1+ 30. Ka2 Rxf1 31. Rxb5 c3 32. Bxf6 Kxf6 33. Ne3 Rf2 34. Rf5+ Ke6 35. Ka3 cxb2 36. Kxb2 h5 37. h4 Rxc2+ 38. Kxc2 Be4+ 39. Kd2 Bxf5 40. Ke2 Ke5 41. Kf3 Bd3 ½ : ½ Caruana – 王皓 (Wáng Hào), Candidates Tournament 2020, Yekaterinburg 2020. 12. ... d5 13. Ng5 Bg4? An unfortunate novelty. A recent correspondence game continued: 13. ... c4 14. Bf1 Bg4 15. f3 Bd7 16. Nh3 b5 17. Kb1 Bxh3 18. gxh3 a5 19. Be5 Qb6 20. Qg5 Rad8 21. Bd4 Bc5 22. Bxf6 Qxf6 23. Qxf6 gxf6 24. h4 Kg7 25. Re2 Rd6 26. Re7 Rfd8 27. Rb7 d4 28. Rxb5 dxc3 29. Rxd6 Bxd6 30. Bxc4 Ba3 31. Bd5 Re8 32. Be4 Rd8 33. Rd5 Rxd5 ½ : ½ Broadway – Sneddon, European Server Championship 2018, Preliminary 25, by correspondence, 2018. 14. f3 Bd7?! One misfortune calls another. 14. ... Bc8 15. c4! was not pleasant at all, but at least would have avoided immediate catastrophe.


15. c4?! Black’s Bishop on d7 allows White to immediately pseudo-sacrifice his Bishop at h7: 15. Bxh7+! with devastating effect. Quite paradoxically, however, Caruana’s move, allowing Black to close the d-file, is not as bad as to definitively compromise his Kingside attacking prospects. 15. ... d4 16. h4 Re8. The immediate 16. ... Bc6 may be a little safer (so as to reply to 17. g4 with 17. ... Bd6). 17. g4 Bc6 18. Qh2 Qa5 19. a3 Bf8. If 19. ... b5 there may follow 20. Nxf7! Kxf7 21. g5 with a crushing attack. 20. Bd2 Qb6 21. Qf4 (Δ Bd3xh7+) 21. ... Bd7. Straight into the fire, but 21. ... h6 22. Nxf7! Kxf7 23. g5+− was hopeless as well.


22. Bxh7+! Repetita iuvant. 22. ... Kh8 (22. ... Nxh7 23. Qxf7+ Kh8 24. Qh5+−) 23. Bf5 Bxf5 24. Qxf5 Kg8 25. h5 Qc6 26. Nxf7 Kxf7 27. g5 Qd7 28. Qg6+ 1 : 0.

1. e4 c5 2. Nc3 Nc6 3. Nge2 Nd4 4. d3 e6 5. Be3 e5. The text (quite possibly a novelty) is more solid than 5. ... Nxe2 6. Bxe2 d6 7. d4 cxd4 8. Qxd4 Ne7 9. Bg5 when an old game continued 9. ...

17. Qh5 Ng6. Taking the Pawn by 17. ... Nxd3 can hardly be good since after 18. Rh4 f6 (not 18. ... h6? on account of 19. Bxh6!) 19. Qxh7+ Kf7 20. Bf3! White enjoys a powerful initiative. 18. Rf2 Qd7 19. h3 f5 20. exf5 Rxf5 21. Rxf5 Bxf5 22. Rf1 Rf8 23. Kh2 b6 24. Bd5+ Kh8 25. d4 Be6 26. Rxf8+ Nxf8 27. Qf3 Bxd5 28. Qxd5 Qe6 29. Qxe6 Nxe6 30. d5 Nc7 31. c4 b5. This natural move is probably wrong. Black ought to continue 31. ... Kg8 in order to reply to 32. Bf4 with 32. ... Ne8 similarly to the game.


32. b3. On her turn, White could have missed here her hidden chance for victory! After 32. cxb5! Nxb5 (32. ... Nxd5 33. Bf4! is even worse) 33. Bf4 c4 34. Bd2! (34. a4? c3!= would lead only to a draw) 34. ... Nc7 35. Kg2 Nxd5 36. Kf3 White, in spite of being temporarily a Pawn down, has a nearly winning endgame, thus confirming the validity of Steinitz’s saying: “The King is a strong piece”. 32. ... bxc4 33. bxc4 Kg8 34.

The Tiffany touch

Ian Alexandrovich Nepomniachtchi – Maxime Vachier-Lagrave
1st Online Nations Cup; Russia – Europe (25+10); chess.com, May 7, 2020
8/8/8/4q3/kp3p2/5R2/5K2/3R4 w - - 16 80

Position after 79. ... Qg5-e5

Even today, old Europe is the only team which has kept pace with China, mostly thanks to the irreducible will of French Grandmaster Maxime Vachier-Lagrave, who somehow succeeded in turning a draw into a win against Russian Grandmaster Ian Alexandrovich Nepomniachtchi. 80. Rf1? White misses the thematic defence consisting in doubling the Rooks on the third rank by 80. Rdd3! with a theoretical draw. 80. ... b3−+ 81. Kg1 Qd4+? 81. ... Qc5+−+ is a tablebases win. 82. Kh2 Qh8+ 83. Kg1 Qg7+ 84. Kh2 Qh7+ 85. Kg1 Qg6+ 86. Kh2 b2 87. Rxf4+ Kb3 88. R4f3+ Ka2 89. R3f2 Qh7+ 90. Kg1 Qd3


91. Kh2? And it was Nepomniachtchi who made the last mistake! 91. Kg2 would have assured a draw. 91. ... Ka3 92. Rf7 Qd6+ 93. Kg2 Qd5+ 94. R7f3+ Ka2 95. Rf2 Ka1 96. Kg3 Qd6+ 97. Kg2 b1=Q 98.

15. ... d5? A grave error that leads to an immediate débâcle, but Krush’s been pursuing a mirage — otherwise 15. ... Rc7 was solid enough. 16. e5 Nfd7 17. Nxb7.

Alice in Euroland

8/6pk/6qp/4Q3/p5P1/PbBp3P/1P1K4/8 w - - 9 46

Position after 45. ... Bc2-b3

Europe was the only team to win both its matches today, especially thanks to Levon Grigori Aronian, who got the most from his games. In the position of the diagram, White continued 46. Qe7, and now, after, let’s say, 46. ... Qf7 (among others) there was little to do rather than sit and settle for a draw. Instead, something happened: 46. ... Bc2? 47. b4!+− axb3 48. Bb2! The pointe. Now the a-Pawn is unstoppable. 48. ... h5 49. g5! h4 50. a4 Kg8 51. a5 Kh7 52. a6! Bd1 53. Kxd1 d2 54. Qxg7+ Qxg7 55. Bxg7 Kxg7 56. Kxd2 1 : 0.

Games Without Losers

The drawing of lots for the inaugural Online Nations Cup, a six-team tournament held May 5–10, just went live at https://www.chess.com/. The pairings for round one are as follows:
  • Europe vs. Russia
  • China vs. Rest of the World
  • India vs. United States
Among the many features of interest are the royal comeback on the worldwide broadcast of four-time Women’s World Chess Champion and world woman No. 1 侯逸凡 (Hóu Yìfán), and the behind-the scenes rivalry between FIDE President Arkady Vladimirovich Dvorkovich and 13th World Chess Champion Garry Kimovich Kasparov as captains of two “meta-nations”, Rest of the World and Europe, respectively. Furthermore, the plot includes a family subrivalry between Anna Olehivna Muzychuk and Mariya Olehivna Muzychuk, whose hearts beat for the Old Europe and the Whole rest of the World, respectively. Last but not least, three-time Women’s World Champion 居文君 (Jū Wénjūn) (China’s reserve team), and two-time Russian Women’s Chess Champion Aleksandra Yuryevna Goryachkina (Russia’s fourth board) can finally give free vent to their pride and prejudice as they enjoy the spotlight of such a gender quota success story.

The Eighth Dwarf

 https://www.ft.com/content/f2214f30-886b-11ea-9dcb-fe6871f4145a
On May 5–10 the global chess body FIDE stages the [Online] Nations Cup of four-player teams, with China the top seeds ahead of Russia, United States, India, Europe, and Rest of the World. FIDE wants all participants in its events to sign a contract accepting expulsion from a tournament if their play shows a high overlap with computer moves.
Such a rule could cause problems in the Nations Cup, where world class players are well capable of preparing an opening in advance for 20 moves or more. [Read more].

Windows on the World

The Fédération Internationale des Échecs (FIDE) announced the Online Nations Cup, a six-team tournament to be held online via the chess.com website from May 5–10, 2020. The participating teams are (in alphaberical order): China, Europe, India, Russia, United States, plus a team representing the “Rest of the World”. At least two former World Chess Champions are due to show up: 13th World Chess Champion Garry Kimovich Kasparov will captain Europe, while 15th World Chess Champion Viswanathan Anand will play first board for India. A remarkable $180,000 prize fund and the rapid time control of 25 minutes each per game plus 10 seconds per move might, or might not, be enough to enchant the audience. A most notable feature of the “Six Nations” may rather be the gender quota imposed by regulation, which requires each team to field at least one female player.
