需求分析 (Requirements analysis)

Sergey Anatoliyovych Fedorchuk – 侯逸凡 (Hóu Yìfán)
18th Corsican Circuit; final game 2 (time control: 15 minutes plus 3 seconds per move); Ajaccio, October 22, 2014

1. e4 c5 2. Nf3 Nc6!? 侯逸凡 (Hóu Yìfán) is well versed in her Sicilians, but it is not so common for her to start the game like this. 3. Nc3. An anti-Sveshnikov move, but I doubt the World Champion was planning to play that with the Black pieces. 3. ... g6. The accelerated Dragon becomes more feasible for top-GMs to play once the Maróczy has been avoided. 4. d4 cxd4 5. Nxd4 Bg7 6. Be3 Nf6 7. Be2. An old but relatively quiet line, Black is not supposed to have too many problems in this variation. 7. Bc4 0-0 8. Bb3 is still the most theoretically challenging line. Black has a few options at her disposal. 7. ... 0-0 8. f4. 8. 0-0 d5 is already known to be equal. 8. ... d6 9. Nb3. This line has fallen out of popularity for a long time now. Black has more than one continuation that promises good play. 9. ... a6. 9. ... Be6 10. g4 d5 11. f5 Bc8 12. exd5 Nb4 13. Bf3 is a famous and old game between Fischer – Reshevsky, [New York 1961, match game 2]. 9. ... a5! is more assertive. 9. ... e5!?. 10. g4. White’s attack on the Kingside in these kinds of situations is usually somewhat slow. It is more visually impactful than dangerous. 10. ... b5 11. g5 Nd7 12. Qd2 Nb6. Black quickly transfers the Knight to the Queenside, hoping to put pressure there quickly. 13. 0-0-0 Na4! This is the point. Now c3 is under attack and Black already has concrete threats. 14. Nd4 Bb7?! 14. ... Nxc3! 15. Qxc3 Nxd4 16. Bxd4 e5!∓ would have been a perfect way to continue the game. White’s structure is falling apart. 15. Nd5 Nxd4 16. Bxd4 e5 17. fxe5 Bxd5! An important strategical decision. White’s Knight on d5 is far more useful for White than the Bishop as Black is embarking on a dark-attack. 18. exd5 dxe5 19. Be3 Qd6?! Letting Fedorchuk slightly off the hook. 19. ... e4! 20. Bd4 (20. c3 b4 is not a position that White can survive) 20. ... Qxd5∓ is a clean Pawn up. 20. Kb1 Rac8. Black still keeps some initiative. Notice that White has not had time to develop anything on the other flank. 21. h4?


21. ... e4?! Missing a brilliant finish. 21. ... Rc3!! This unusual move wins on the spot. The point is that b4 is now clear for the Queen, making the attack on the Queenside far more dangerous. The Rook is clearly taboo. 22. Ka1 (22. bxc3 Qa3 with unstoppable mate following up) 22. ... e4 23. Rb1 Ra3!. 22. Bd4 Qxd5 23. Qe3 Bxd4 24. Rxd4 Qc5 25. c3 Rfd8 26. Rhd1 Rxd4 27. Rxd4 Re8. At the end of the day White has survived the attack. He is down a Pawn but can regain it in the next move, though he would still be a little worse. 28. h5? (28. Bf3! Qf5 29. Bxe4 Qf1+ 30. Qc1 Qf2⩱) 28. ... Qe5 29. h6 Nc5? Already with both players in time pressure both players miss an important resource here. 30. Bg4? 30. c4! White has the strong threat of Rd4-d5, and its surprisingly difficult to stop! 30. ... Kf8 31. a3 Ne6 32. Bxe6 Qxe6 33. a4 Qf5. Black is now up a Pawn. It is difficult to convert, but it helps when all you need is a draw. 34. a5 Qf3! 35. Qxf3 exf3 36. Rf4 Re1+ 37. Kc2 Re2+ 38. Kb3 f2 39. Ka3 (39. Rf6◻=) 39. ... f5! A nice move. This clears the path for Black’s King as the Pawn cannot be taken. 40. b3 (40. gxf6 g5−+) 40. ... Ke7 41. Rf3 Ke6 42. Kb4 Kd5 43. Rf4 Re4+ 0 : 1. 44. c4+ bxc4 45. Rxf2 cxb3+ 46. Kxb3 f4 is very hopeless.

La Storia

Victoire historique de 侯逸凡 (Hóu Yìfán)!
A l’exception de Judit Polgár, aucune joueuse n’avait gagné un tournoi aussi important. Elle a battu le bourreau de Vishy Anand par le score sans appel de 2-0. Sergey Fedorchuk a pourtant tout tenté pour égaliser, mais la force tactique de la chinoise a eu raison de son acharnement. 500 personnes, debout, ont longuement ovationné la championne du monde qui les a conquis par son talent et sa disponibilité. Le plus dur restait à faire pour elle, signer des dizaines d'autographes à de jeunes, et moins jeunes, fans. [Read more].

1. e4 c5 2. Nf3 Nc6 3. Nc3 g6. Playing the Dragon is obviously highly symbolic... 4. d4 cxd4 5. Nxd4 Bg7 6. Be3 Nf6 7. Be2 0-0 8. f4 d6 9. Nb3 a6. More usual is 9. ... a5 10. a4 Be6 11. 0-0 Rc8 with fairly even chances. 10. g4. For 10. a4 Be6 11. 0-0 Rc8 12. f5 Bxb3 13. cxb3 Nb4 14.

Worth considering was 30. c4. 30. ... Kf8 31. a3 Ne6 32. Bxe6 Qxe6 33. a4 Qf5 34. a5? Going into a much unfavorable endgame. Correct was 34. Rd1!, e.g. 34. ... a5 35. c4!? bxc4 36. Qa3+ Kg8 37. Qe7! Qe6 with even prospects. 34. ... Qf3! 35. Qxf3 exf3 36. Rf4 Re1+ 37. Kc2 Re2+ 38. Kb3 f2


39. Ka3? The decisive mistake. More resilient was 39. Rf6, even though after 39. ... Ke7 40. Ka3 Re5 41. Rxf2 Rxg5 Black’s extra Pawn will tell pretty soon in the endgame. 39. ... f5! Simply threatening to bring her King to e5. 40. b3. 40. gxf6 is met by 40. ... g5. 40. ... Ke7 41. Rf3 Ke6 42. Kb4 Kd5 43. Rf4 Re4+. Of course, 43. ... Ke5 would have won immediately, but also the text is sufficient to win. 0 : 1. For if 44. c4+ then 44. ... bxc4 45. Rxf2 cxb3+ 46. Kxb3 f4 with an easy win.

1. e4 e5 2. Bc4 Nc6 3. d3 Bc5 4. Nc3 d6 (4. ... Na5 5. Nge2) 5. Na4 Na5. For 5. ... Bb6 6. Nxb6 axb6 7. f4 take a look at Spielmann – Przepiórka, 15th DSB Kongress, Nuremberg 1906, whereas for 5. ... Nf6 6. Nxc5 dxc5 7. f4 see Spielmann – Olland, Scheveningen 1923. 6. Bb3 Nxb3 7. axb3 Ne7 8. Nf3 Ng6 9. h3 a6 10. Nxc5 dxc5 11. Be3 Qe7 12. 0-0 0-0 13. Nd2 Be6 14. Kh2 b6 15. Nc4 a5 16.

27. ... Ra1? Sounder seems 27. ... Rf7 28. Rgf3 and White has at least a slight edge. 28. Qxc7 Rg8 29. Qf4 b5 30. Nd6 Bxb3 31. Nxb5 Qd7 32. Nd6 Be6 33. e5 fxe5 34. Qxe5 Ra7 35. Ne4 c4. Not a panacea, but 35. ... Qd5 would be met by 36. Rg5 as afterwards in the text. 36. Nc5. Sufficient to win, but possibly sharper – and stronger – seems 36. Ng5! Bd5 37. cxd5 and Black is doomed (e.g. 37. ... Bxc4?? 38. Qe4+−). Another good move is 36. Nf6, after which Black is practically compelled to give up the Exchange, as after 36. ... gxf6 37. Qxf6+ Rg7 38. Rxg7 Qxg7 39. Qxe6 the game is over. 36. ... Qd5 37. Rg5 Qxe5+ 38. Rxe5 Bf7 39. dxc4 Bxc4 40. b3 Bf7 41. Ref5 Bg6 42. Rf8 h6 43. b4 Ra1 44. Rxg8+ Kxg8 45. Rb2 Rc1 46. Nd7 Be8 47. Ne5 Bb5 48. Kg3 Re1 49. Nf3 Re4 50. Nd2 Re2 51. Kf3 g5 52. Nc4 Re5?? A blunder. The lesser evil would been 52. ... Rxb2 53. Nxb2 Bc6+ 54. Kf2 and White is a Pawn ahead, which should be sufficient to win. 53. Nxe5 1 : 0.

Corsica Finals: Hóu Yìfán vs. Sergey Fedorchuk
Dennis Monokroussos, The Chess Mind, October 20, 2014

[...] Hóu Yìfán made things as difficult for herself as possible before qualifying for the finals. As she did yesterday, she began her quarterfinal match with Martyn Kravtsiv by losing with the white pieces. As yesterday, she won the rematch and then won the blitz playoff 2-0. In the semi-final round she unexpectedly played Robert Ruck, who had defeated second seed Ivan Saric 1½–½, winning the second game with the pieces.
In the Hóu–Ruck match Hóu broke the pattern by winning the first game with White, but the overall pattern of needing to suffer continued intact. She lost the second game, and then lost the first blitz game to boot – both losses were with Black. She won the second blitz game, and then it was time for an Armageddon game. She had White and five minutes against Ruck’s four minutes and draw odds, and she came through with a good win. [Read more].

“This marriage is not to be performed”...

Breaking news from the Lega Corsa di Scacchi (Ligue Corse des Échecs) website:

Finale 侯逸凡 (Hóu Yìfán) – Fedorchuk
Le Tigre de Madras n’a pas suffisamment rugi. On pensait que rien ne pouvait l’empêcher d’atteindre la finale ajaccienne tant il a avait dominé ses adversaires lors des 1/8 et 1/4 de finale.

侯逸凡 (Hóu Yìfán) & Viswanathan Anand: “This marriage is not to be performed”... Photo: Lega Corsa di Scacchi.

Pendant ce temps Hóu Yìfán devait disputer ses 3e tirs au but. En 1/8 et en 1/4 elle s’était incliné avec les blancs et revenu au score avec les Noirs. Les départages en 3+2 lui avaient été favorables. Elle gagne en 1/4 de finale avec les blancs. On se dit, cette fois-ci pas de départage. Que nenni… Elle perd avec les noirs face au brillant Grand Maître Hongrois Robert Ruck. Et puis la dégringolade continue, elle perd le 1er départage et est en position perdante, une qualité de moins, dans la revanche. C’est fini... Non, la chinoise est pleine de ressource et d’idées. Elle arrache une inespérée victoire. C’est la mort subite. Robert Ruck gagne le tirage au sort. La chinoise est donc guignarde aussi? Le hongrois choisit les noirs avec 4 minutes face à des blancs qui auront 5 minutes mais l’obligation de gagner. Robert Ruck a ensuite confié les raisons de ce choix aux organisateurs “je suis un joueur solide avec les noirs, j’ai choisi cette voie pensons pouvoir tenir le choc”. Malheureusement il avait en face de lui le talent à l’état pur. Il suffit de regarder cette partie pour en être persuadé.
La finale opposera donc le Grand Maître Ukrainien [Sergey Fedorchuk] à la championne du monde ce mecredi à 14h dans le superbe cadre du palais des Congrès dAjaccio. Les 400 spectateurs présents auront droit, en plus, à des commentaires ouverts, sans casque. C’est aussi cela la particularité du Corsican Circuit! [Read more].
