Uncountable set

Francisco Vallejo Pons – Arshak Bagratovich Petrosian
2nd FiNet Chess960 Open; time control: 20 minutes plus 5 seconds per move; Mainz, August, 2003
bbnrkrqn/pppppppp/8/8/8/8/PPPPPPPP/BBNRKRQN w FDfd - 0 1

Position #352

1. c4 c5 2. b3 e5?! A very dubious gamble. 2. ... Ng6 was a solid and good reply.
3. f4! Vallejo Pons claims the initiative with emphasis. If 3. Nd3 Black can reply with 3. ... d6 4. f4 f6 aiming at holding on to control.
3. ... b6?! Black prefers to give up rather than accept a Pawn, a decision which probably his position does not justify. Whether good or bad, it was time to put cards on the table: 3. ... exf4 4. g3!↑ with the upper hand for White.
4. fxe5 Ng6 5. Nd3 d5!? 6. cxd5 Bxd5 7. Ng3 Nce7 8. Rc1 Nc6 9. Qe3 0-0-0?! To say it with Bobby Fischer, add another to those melancholy case histories entitled “castling into it”. On the other hand, there is no easy solution for Black; for example: 9. ... Bxg2 10. Rg1 Bd5 11. Nf5 with a dominating advantage for White.


10. b4! Natural and strong. Nonetheless, 10. Nxc5! bxc5 11. Qxc5 would also have been hopelessly crushing (if now 11. ... Bxg2? then 12. Be4!+−).
10. ... Rfe8 11. bxc5 b5


12. Nf5! Threatening check at d6.
12. ... Ngxe5 13. Nxe5 Bxe5 14. Bxe5 Rxe5 15. Qxe5! A little tactic which yields White both a material and positional advantage.
15. ... Nxe5 16. Ne7+ Kc7 17. Nxg8 Rxg8 18. 0-0. Sic et simpliciter: White intends to advance his Pawns in the centre with devastating effect. Black can prevent it only at the cost of further losses.


18. ... Nc6 19. Bxh7 Re8 20. Bd3 a6 21. a4 bxa4 22. Bc4 Bxc4 23. Rxc4 f6 24. e3 a3 25. Ra1 Rb8 26. Rxa3 Rb2 27. d4 a5 1 : 0.

Centralcasting

侯逸凡 (Hóu Yìfán) – Francisco Vallejo Pons
Grand Prix 2017; 2nd stage; Moscow, May 20, 2017
French Defence C12

1. e4 e6 2. d4 d5 3. Nc3 Nf6 4. Bg5 Bb4 5. exd5 Qxd5 6. Bxf6 Bxc3+ 7. bxc3 gxf6 8. Qd2 Qa5 9. Bd3 Bd7 10. Ne2 Bc6 11. f3 Nd7 12. c4!? An interesting new approach. 12. ... Qxd2+ 13. Kxd2 Nb6 14. h4 Rg8 15. Rhg1 Rd8 16. Ke3. White should have a slight edge, even though, quite strangely, it rapidly disappears like clouds on a sunny day. 16. ... Ke7 17. g4 h6 18. Rab1 Nc8 19. Nc3 b6 20. a4 Nd6 21. Nb5 Ne8 22. a5 Bxb5 23. Rxb5? A cryptic decision, apparently aiming for further simplifications at a very high price, even though, quite miraculously, White will not end up crossing the point of no return. By 23. axb5 she would apparently have kept the upper hand. 23. ... f5 24. axb6 axb6 25. c5 Nf6 26. cxb6 cxb6 27. Be2. White’s game soon became uncomfortable, and 侯逸凡 (Hóu Yìfán) must maintain her coolness and balance to keep together her own position. 27. ... Nd5+ 28. Kd2 Nf4 29. c3 Rc8 30. Bf1 h5! 31. c4 hxg4 32. fxg4 fxg4 33. Rxb6 f5 34. Ke3 Nh3 35. Bxh3. Engines do not like this move, and, from a human viewpoint, it’s hard to disagree. But what follows shows that 侯逸凡 (Hóu Yìfán) quite well knew what she was doing. 35. ... gxh3 36. Rxg8 Rxg8 37. Rb1 Rh8


38. d5! An amazing way out of the blue. 38. ... exd5. Also 38. ... e5 39. c5 Rxh4 40. Kf2 Rd4 41. Rb7+ Kd8 42. d6 Rd2+ 43. Kg1! e4 44. Re7 Rd5 45. Kh2 Rxc5 46. Kxh3 Rd5 47. Rf7 should end in a draw. 39. cxd5 Rxh4 40. Kf2 Kd6 41. Kg3 Rh5 42. Kh2 Kxd5. In spite of Black’s two extra Pawns the endgame is a book draw or, rather to better say it, a “Nalimov Endgame Tablebases” draw. 43. Rb5+ Ke4 44. Rb4+ Ke5 45. Rb5+ Kf6 46. Rb1 Rh4 47. Rb3 Ke5 48. Rb5+ Kf4 49. Rb3 Rh8 50. Rb1 Ke3 51. Rb3+ Kd2 52. Rb2+ Kc3 53. Rb5 Rh5 54. Rd5 Kc4 55. Rd8 Kc5 56. Rd7 Kb6 57. Rd3 Kc6 58. Rd8 Rh4 59. Rf8 f4 60. Rd8 Kc5 61. Rd7 Kc6 62. Rd3 Rh8 63. Rxh3 Rxh3+ 64. Kxh3 Kd5 65. Kg2 Ke4 66. Kf2 f3 67. Kf1 Ke3 68. Ke1 f2+ 69. Kf1 Kf3 ½ : ½. “Chinese torture”, then Vallejo tweeted.

Vesta case

Francisco Vallejo Pons – Prantik Roy
15th Bangkok Chess Club Open; Bangkok, April 13, 2015
Tarrasch Defence D41

1. Nf3 Nf6 2. c4 e6 3. Nc3 d5 4. d4 c5 5. cxd5 exd5 6. Bg5 Be6 7. e3 c4 8. Be2 Nc6. For 8. ... Be7 9. 0-0 0-0 10. Ne5 Nfd7 see Penrose – Ed. Lasker, 28th Hastings Christmas Chess Congress, Hastings 1952/1953. 9. 0-0 Bb4 10. Ne5 Bxc3 11. bxc3 h6 12. Bxf6 Qxf6 13. f4 Bf5 14. Bf3 Qd6 15. e4 dxe4 16. Nxc4 Qg6 17. Bh5 Qf6 18. Ne3 0-0 19. Rb1 g6? A very bad move which fatally weakens the Kingside. Better was 19. ... b6 in order to answer 20. Rb5 with 20. ... Bc8. 20. Bg4! Bc8. Now, after 20. ... b6 21. Bxf5 gxf5 22. Rb5 Ne7 23. Re5 White’s position looks imposing. 21. f5! Qg5 22. Qe1 b6 23. h4 Qd8 24. Qg3 Ba6 25. Rf4! g5


26. f6! An extremely elegant solution! 26. ... Qd6. The Rook is taboo, as 26. ... gxf4 runs into a mating net by force after 27. Qxf4 followed by Qf4xh6. 27. hxg5 hxg5 28. Qh3! 1 : 0. For if 28. ... gxf4 then 29. Bf5 and mate in two moves, whilst after 28. ... Qxf4 both 29. Qh6 and 29. Nf5 would force a quick mate.

Easy Livin’

Ruslan Olegovich Ponomariov – Francisco Vallejo Pons
7th Grand Slam Masters; Bilbao, September 16, 2014
Sicilian Defence B90

1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. h3. “Black’s loss of time with ... a7-a6 may possibly justify this loss of time”, wrote Bobby Fischer in his “My 60 Memorable Games”, New York, Simon and Schuster, 1969, page 212. 6. ... e6 7. g4 Be7 8. Bg2 Nfd7 9. Nce2. Another try is 9. Be3 Nc6 10. Qe2 Nxd4 11. Bxd4 0-0 12. 0-0 b5 13. e5 d5 14. a3 (14. f4!?) 14. ... Qc7 15. f4 Bc5 16. Qe3 Bxd4 17. Qxd4 Bb7 18. Rae1 Rac8 with roughly equal chances, 侯逸凡 (Hóu Yìfán) – 王皓 (Wáng Hào), Chinese Chess Championship, 兴化市 (Xīnghuà) 2009. 9. ... Nc6. For 9. ... Qc7 10. Be3 b5 see Vibbert – Sarkar, Arlington 2013. 10. c3 h5? Risky play, in the style of the Spanish Grandmaster. 10. ... Qb6 was worth considering. 11. gxh5 Rxh5? As then tweeted by Vallejo Pons: “Hoy derrota inapelable, Ponomariov no me dio opción tras 11. ... Rxh5? – Esas cosas pasan. A ver si no me quedo peor/perdido en 12 un día XD”. 12. Nxc6 bxc6 13. Nd4 Rc5. Sadly forced. 14. b4! An energetic refutation! 14. ... Rxc3. The Exchange sacrifice 14. ... Rc4 15. Bf1 Rxd4 16. cxd4 can hardly be regarded as a way out. 15. Bb2 Rc4


16. Nxe6! “I missed 16. Nxe6. That means I’m already lost after 11. ... Rxh5. Sometimes this happens”, said Vallejo Pons. “He played well”. 16. ... Qb6. Clearly not 16. ... fxe6 17. Qh5+ Kf8 18. Qh8+ Kf7 19. Qxg7+ Ke8 20. Qg6+ Kf8 21. Bg7+ Kg8 22. Bh6+ and mate next move. 17. Nxg7+ Kf8 18. 0-0 Ne5 19. Nh5 Qxb4 20. Rb1 Qc5. If 20. ... Qa5 then 21. f4 Ng6 22. Bg7+ Kg8 (else 22. ... Ke8 23. Nf6+ Kd8 24. f5 Ne5 25. Ng8 winning) 23. f5 Ne5 24. Kh1! (Δ Rf1-g1) with an irresistible attack. 21. Kh1! Simply intending the deadly f2-f4. 21. ... Ng6 22. Nf6 Rb8. Anything but good, but also after 22. ... Ne5 23. f4 Ng6 24. f5 Ne5 25. Nh7+ Kg8? 26. Rg1! White wins. 23. Qd2. Another way was 23. Bc1! with overwhelming threats. 23. ... Bxf6 24. Bxf6 Rb5 25. Rbd1 d5 26. Qh6+ Ke8 27. exd5 cxd5 28. Rfe1+ Kd7 29. Qg7 Qf8 30. Bxd5 Rxd5 31. Rxd5+ Kc7 32. Be5+ Kc6 33. Qxf8 1-0. For if 33. ... Nxf8 then 34. Rd8 wins a piece. “Today I was lucky that I got this position with so much initiative so easily and so quickly. At some point I only needed to calculate well as to not spoil it”, said Ponomariov. “It’s very difficult to defend for Black”.

Noli me tangere

Wesley So – Francisco Vallejo Pons
49th Capablanca Memorial; Havana, May 9, 2014
Spanish Game C67

1. e4 e5 2. Nf3 Nc6 3. Bb5 Nf6 4. 0-0 Nxe4 5. d4 Nd6 6. Bxc6 dxc6 7. dxe5 Nf5 8. Qxd8+ Kxd8 9. Nc3 Bd7 10. b3 Kc8 11. Bb2 b6 12. Rad1 h6 13. h3 a5. Neither 13. ... c5?! 14. Nd5 nor 13. ... Be6?! 14. g4 Ne7 15. Nd4 are too satisfactory for Black (Kramnik’s analysis). The alternative, if anything, is 13. ... Ne7!? 14. Ne2 Ng6 15. Ne1!? h5! 16. Nd3 c5 17. c4 a5 18. a4 h4 19. Nc3 Be6! 20. Nd5 Kb7 21. Ne3 Rh5!= Kasparov – Kramnik, London 2000, match game 1. 14. Rd3. Another try is 14. a4 Ne7 15. Ne2 Ng6 16. Ng3 Nf4 17. Rfe1 c5 18. Re4 Ne6 19. c4 Bc6 20. Re3 Kb7 21. Rd2 Be7 22. Nf5 Bg5 23. Nxg5 Bxg5 24. f3 Rad8 25. Red3 Rde8 ½ : ½ Vallejo Pons – I. Sokolov, Mondariz Balneario 2001, match game 3. 14. ... Ne7. Less convincing looks 14. ... Bb4 15. Ne4 Be6 16. g4 Bd5 17. Nfd2 Bxd2 18. Nxd2 Nh4 19. f4 Kb7 20. e6 with advantage to White, Nijboer – Jonkman, Wijk aan Zee 2002. 15. Rfd1 Bf5 16. R3d2. White refuses to be content with the simple and dry continuation 16. Rd8+ Kb7 17. Rxa8 Kxa8 18. Nd4 Bc8 19. e6 f6 (19. ... fxe6 20. Re1) 20. Re1 Kb7 21. g4 h5 22. Nf5 hxg4 23. hxg4 Ka6 as in the game Hybl – Nejtek, by correspondence, 2010. 16. ... c5 17. Nb5 Nc6 18. Nh4 Be6 19. f4 g6 20. g4 Be7 21. Ng2 Kb7


22. Nd6+! By this propitiating pseudo-sacrifice White tries to change the aspect of the fight. 22. ... cxd6 23. exd6 Rhd8 24. dxe7 Rxd2 25. Rxd2 Nxe7 26. a4 Nc6 27. Ne3 Re8 28. Kf2 f5 29. Bg7 h5 30. gxh5 gxh5 31. c4 Rg8 32. Bc3 Kc7 33. Be5+ Nxe5 34. fxe5 h4? A serious mistake, leading to a débâcle. Correct was 34. ... f4! 35. Ng2 Rg5= or, for the better, 35. Nd5+ Bxd5 36. cxd5 Rg3 with excellent drawing chances. 35. Rd6 Re8. There’s no turning back. If 35. ... f4 then 36. Ng2 Bxh3 37. Nxf4 and wins. 36. Kf3 f4 37. Nd5+ Bxd5+ 38. Rxd5 Rf8 39. Rd2 Rf7 40. Rd1 Rf8 41. Rd2. White has been gaining time on the clock. 41. ... Rf7 42. e6! Masterly liquidation! 1 : 0. For after 40. ... Re7 41. Rd7+! is an easily won ending.

Larsen A01

1. b3 d5 2. Bb2 Bg4 3. f3 Bf5 4. e3. For 4. f4 e6 see Basman – Timman, London 1975. 4. ... Nf6 5. g4 Bc8 6. g5 Nfd7 7. Nc3 e6 8. f4 c5 9. Nf3 Nc6 10. Qe2 a6 11. h4 Rg8 12. f5 Nb6 13. g6 hxg6 14. fxg6 f6. If 14. ... fxg6 then 15. Qg2. 15. d4 Qc7 16. 0-0-0 Bd7 17. Bh3 0-0-0 18. Kb1 f5. I would have preferred 18. ... Kb8 19. h5 c4∞. 19. Ng5 c4 20. e4! Offering a Pawn and opening up the position. 20. ... dxe4 21. d5! exd5 22. Nxd5 Nxd5 23. Rxd5 c3 24. Bxc3 Ne7 25. Rd4


25. ... Nxg6? The Bishop cannot, of course, be captured, since 25. ... Qxc3?? loses to 26. Rc4+, but also the text is a gross blunder. More resilient is 25. ... Kb8 although after 26. Qc4 White maintains a clear advantage, e.g. 26. ... Qxc4 27. bxc4 Nc6 28. Rxd7 Rxd7 29. Bxf5 etc. 26. Rc4 Bc5 27. b4 Bb5 28. bxc5 Nf4 29. Bxf5+ Kb8 30. Qxe4 Rge8 31. Ne6 Rxe6 32. Bxe6 Bc6 33. Bd4. Probably a typo. You’d better to read 33. Be5 or 33. Qxf4. 1 : 0.
