牛顿的苹果 (Newton’s Apple)

Wijk aan Zee, January 12, 2015. Yasser Seirawan speaking with Vassily Mykhaylovych Ivanchuk after his win against Loek van Wely. “When you’re in good form, you are capable of really great chess. This is fantastic!” — Seirawan tried to keep the conversation alive but got the answer: “I want just to ask: after tomorrow, the bus will be at eleven fifteen, right?”.

Lose to Win

Just two lines by Gyro Gearloose

Boris Vasilievich Spassky – Yasser Seirawan
Candidates Tournament; Montpellier, October 12, 1985
King’s Gambit C34

1. e4 e5 2. f4 exf4 3. Nf3 Ne7. Not so popular. Its main purpose is to avoid the well-known theoretical variations. 4. d4. For 4. Bc4 d5 see Spassky – Averbakh, 22th USSR Championship, Moscow 1955. 4. ... d5. 4. ... Ng6? is bad due to 5. h4 Be7 6. h5 Nh4 7. Bxf4 d5 8. Nxh4 Bxh4+ 9. g3 (analysis by Kortschnoi and Zak). 5. Nc3. Another try is 5. e5 Ng6 6. Bd3 Nh4 7. 0-0 Nxf3+ 8. Qxf3 g5 9. g3 (Levenfish). 5. ... dxe4 6. Nxe4 Ng6 7. h4! More energetic than 7. Bc4 Be7 8. h4 Nxh4 9. Ne5 Nc6 10. Bxf7+ Kf8 11. Nxc6 bxc6 12. Bb3 Bf5 13. 0-0 f3 14. gxf3 Qe8 15. Kf2 h6 with chances for both colors, Spassky – Novopashin, 30th USSR Championship, Yerevan 1962. 7. ... Qe7!? Seirawan tries to improve on the game 7. ... Be7 8. h5 Nh4 9. Bxf4 Bg4 10. h6! 0-0 11. hxg7 Re8 12. Kf2 with with great advantage for White, Kuznetsov – Boch-Osmolovsky, Moscow 1964.

8. Kf2!! This appears to be White’s best move. 8. ... Bg4. On 8. ... Qxe4 9. Bb5+ c6 (or 9. ... Kd8 10. Re1) 10. Re1 Qxe1+ 11. Qxe1+ wins. 9. h5 Nh4 10. Bxf4 Nc6 11. Bb5! 0-0-0 12. Bxc6 bxc6 13. Qd3 Nxf3 14. gxf3 Bf5 15. Qa6+ Kb8 16. Nc5 Bc8 17. Qxc6 Rxd4. The only way to struggle on, since White was threatening Ra1-e1-e3-b3+. 18. Rae1! Rxf4. Clearly not 18. ... Qxc5?? on account of 19. Bxc7 mate nor 18. ... Qd8 in view of 19. Re8! winning. 19. Qb5+ Ka8 20. Qc6+ Kb8 21. Rxe7 Bxe7 22. Rd1 Rf6 23. Nd7+ Bxd7 24. Qxd7 Rd8 25. Qb5+ Kc8 26. Rxd8+ Bxd8 27. Qa4! g5 28. Qxa7 Rf4 29. Qa6+ Kb8 30. Qd3 Be7 31. Qxh7 g4 32. Kg3! 1 : 0.

诸宸 (Zhū Chén) & Yasser Seirawan – 侯逸凡 (Hóu Yìfán) & Nigel D. Short
成都 (Chéngdū), July 8, 2014
Nimzo-Indian Defence E34

As observes Mark Crowther (The Week in Chess, July 9, 2014): “Nigel Short and Hóu Yìfán were favourites to win after being paired together but as Short said afterwards: ‘Basically we blew it yesterday with a collective collapse of concentration against Yasser Seirawan and Zhū Chén, turning a clearly better position into a dead lost one in the space of about two minutes (and half a dozen moves)’. They finished 3rd behind the teams of Zhū Chén/Yasser Seirawan and Xǔ Yùhua/Yú Shǎoténg both finishing on 4/5”.

1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. Qc2 d5 5. cxd5 Qxd5 6. Nf3 Qf5 7. Qb3 Nc6 8. e3. If 8. a3?! then 8. ... Ba5 9. e3 0-0 10. Qb5 e5 11. Bd3 Qg4 12. 0-0 a6 13. Qb3 (Beljavskij – Short, Las Vegas 1999, match game 1) 13. ... exd4 with a slight edge for Black. 8. ... a5. For 8. ... 0-0 9. Be2 e5 (9. ... a6 10. 0-0 Bd6! is worth considering, e.g. 11. e4? Nxe4 12. Bd3 Qh5! 13. Bxe4 Nxd4-+) 10. d5 Bxc3+ 11. bxc3 Na5 12. Qa4 b6 13. c4 see Nakamura – Tkachiev, Santo Domingo de Guzmán 2002. 9. a3 a4 10. Qd1 Bxc3+ 11. bxc3 e5 12. Be2 0-0 13. 0-0 Re8 14. Bb2. An odd way to play. 14. ... e4 15. Nh4 Qg5 16. g3 Bg4 17. c4 Na5 18. Bxg4 Qxg4 19. Qxg4 Nxg4 20. Rac1 Ra6! Such a wonderful manoeuvre! 21. Rc2 Rc6 22. Rfc1 Nb3 23. Rd1 b5. Black’s superiority is manifest. 24. c5 Rd8. With the threat of ... Rc6xc5. 25. Rf1. Of course not 25. h3? on account of 25. ... Ne5 with disruptive effects. 25. ... Re6 26. Ng2

26. ... c6? Says Marmot PFL: “26. ... g5 keeps White’s Knight out of play and Black can play ... Ng4-f6-d5 with a bad game for White. White probably has to play 27. f4 exf3 28. Rxf3 but Black should still be fine”. And right you are, Mr. Human! After 28. ... h6 Black stands better. 27. Nf4 Ree8 28. d5 cxd5. Also 28. ... Kf8 29. dxc6 Rc8 was safe. 29. c6 d4 30. c7 Rc8 31. Bxd4 Nxd4? A fatal slip. After 31. ... Re7 32. h3 Nxd4 33. exd4 Nf6 the game is even. 32. exd4 Re7? The final error. A lesser evil was 32. ... e3 33. f3 Nf6 34. Rb1 g5 35. Ng2 Re7 36. Rxb5 Rexc7 37. Rxc7 Rxc7 38. Rxg5+ Kf8 39. Rc5 with huge advantage to White. 33. Nd5+- Rd7 34. Rc5 h6 35. Rfc1 1 : 0.
