Llegada de los jugadores
Todo el mundo del ajedrez sabe lo gran teórico que es Anish Giri is. Sin embargo, de vez en cuando alguien intenta ponerlo a prueba y la mayor parte de las veces el experimento sale mal. Hoy Hikaru Nakamura traía todo preparado con blancas para jugar la variante Merano de la Semieslava. Anish pisaba con cuidado, no porque no supiese la variante, sino porque estaba intentando recordar sus análisis. Encontró todos los recursos con negras y evitó todas las trampas que le iba poniendo Nakamura. El resultado fue de tablas en menos de una hora. Así es el ajedrez moderno: planteas una novedad en una línea aguda y si el rival no la ha estudiado, es quemado vivo, pero su la ha preparado, la partida termina en tablas. En todo caso, fue una partida importante al menos en lo que concierne al desarrollo teórico de la variante.

Breves declaraciones de Anish Giri tras su partida de la ronda 4
Peter Svidler parece más que bien preparado para esta competición. En la variante de la apertura Inglesa con 5.e4, una línea que ha sido popularizada por Anish Giri, Aronian jugó una novedad con 9…Cc5!, pero era en cierto modo esperado, ya que las demás jugadas empleadas en la posición no eran tan buenas. Peter tenía preparada la variante con mucha profundidad, hasta la jugada 18.
Al comienzo Aronian estaba a la altura de las circunstancias. Logró sobrevivir a la apertura y llevó la partida a una posición relativamente igualada. Una imprecisión en el movimiento 22 significó que el ruso pudo presionar de nuevo. Aunque la posición era agradable, no fue suficiente para construir una victoria. Al final se cambiaron muchas piezas y peones y con torre y tres peones por bando, la partida fue tablas.

Han jugado 26 partidas contando relámpago, rápidas y clásicas y Karjakin nuna había sido capaz de ganar a Vishy Anand. “Estoy muy contento porque hoy he conseguido mi primera victoria en ajedrez clásico contra Anand”, dijo Sergey cuando se le preguntó por la partida. Karjakin ha mostrado un completo desdén por las continuaciones teóricas en esta competición, especialmente con blancas. Contra Svidler escogió la relativamente poco ambiciosa 9.Cxd4!? y hoy contra Anand planteó con esa idea tan interesante de 8.Dc2 seguido por 9.h4!? Sergey dio las gracias a sus ayudantes que habían trabajado muy duro para preparar esa novedad. Como certeramente señaló Peter Svidler, “Para jugar variantes no teóricas, hay que saber mucha teoría”. Tras la apertura Vishy tenía una posición relativamente buena, pero tras una pequeña imprecisión 18…Aa6 seguido por un error mayor 21…Dd6 el indio ya tenía una posición muy desagradable. El final resultante era tan pasivo para las negras que Karjakin pudo tomarse su tiempo de disfrute para asestar el golpe final. Una impresionante victoria de Sergey.

There have been eight decisive results all in the favour of Vishy Anand. Naturally the Indian ace has a psychological edge when facing the young Russian.} 1. Nf3 {Karjakin sticks to his policy of beginning the game with 1.Nf3 as he did against Svidler and Nakamura.} d5 2. e3 $5 {Although not completely silly, this is a highly unambitious move. In a way it takes away quite a bit of flexibility in from White's setup and makes d4 lines pretty harmless. Karjakin's natural inclination was towards avoiding Vishy Anand's home preparation.} Nf6 3. c4 e6 4. b3 Be7 5. Bb2 O-O 6. Nc3 c5 7. cxd5 Nxd5 {The game has transposed into a well-known position and it looks like we would follow some of the classical games like the ones played by Botvinnik, Larsen, Smyslov etc. However, Sergey gives this position his own modern touch!} 8. Qc2 $5 Nc6 9. h4 $5 $146 { [%cal Gh2h4] The highly interesting novelty. The idea of this move is to prepare Ng5 at some point and force White to weaken his kingside with a pawn move.} b6 10. a3 (10. Ng5 f5) 10... f5 {Anand tries to be safe and shuts the b1-h7 diagonal. What he should be really careful about is the fact that he is extending his position and some of the squares might become weak due to these pawn moves.} 11. Bb5 Bb7 12. Nxd5 exd5 (12... Qxd5 {was definitely a worthwhile alternative.} 13. Bc4 Qd6 14. Ng5 Bxg5 15. hxg5 Na5 {should not be such a huge problem for Black.}) 13. d4 {After playing the move h4, suddenly Karjakin switches to positional chess! Something has not really gone according to his plan, or has it?!!} Rc8 14. dxc5 bxc5 15. O-O {After the game I was curious as to why Sergey, who seemed all aggressive and wanted to blow Anand off the board, had suddenly become positional and played moves like d4 and 0-0. Well the reason is as simple as Karjakin explains after the game. "I wanted to provoke him into playing f5 and that's what he did!"} Bf6 (15... f4 16. Bd3 $1 $16) 16. Rfd1 (16. Bxf6 Qxf6 17. Qxc5 Ne5 $44) 16... Ne7 17. Bxf6 Rxf6 18. g3 { The position is around equal at this point. It is a well know fact that the side with the isolated or hanging pawns must keep more pieces on the board. Anand's next move breaks this rule and looks clearly like a positional error.} Ba6 $6 {[%cal Gb7a6] More the pieces get exchanged, more the c5 and d5 duo start becoming weak.} 19. Bxa6 Rxa6 20. Qc3 Rb6 21. Rac1 Qd6 $6 {Another inaccuracy. The queen is not at all well placed on d6. As Sergey shows Ne5 will threaten moves like Nc4 and Nd3.} 22. Ne5 $1 Rb7 23. Nd3 $1 {And this is what we were talking about. The hanging pawns become super weak. The c5 pawn advances and the rest is just pain for the Indian champion.} c4 24. bxc4 Rxc4 25. Qe5 {The queens have to be exchanged.} Qxe5 (25... Qc6 26. Rxc4 dxc4 27. Nc5 $18) 26. Nxe5 Rxc1 27. Rxc1 $16 {White has a better knight, a better rook, a better pawn structure and a clear plan of improving his king. The rest as they say is a matter of technique for a strong player like Karjakin.} g6 28. Rc5 Kg7 29. Ra5 Kf6 30. Nd3 Rc7 31. Ra6+ Kg7 32. Nf4 Rd7 33. Kf1 Ng8 34. Ne6+ Kf7 35. Nd4 Ne7 36.

Karjakin tras su primera victoria sobre Anand en ajedrez clásico
Fue un refrescante cambio en la apertura ya que Caruana, en vez de plantear la Ruy Lopez, jugó el Giuoco Piano. Ambos ajedrecistas manejaron la fase de apertura bastante bien y la posición era relativamente equilibrada. En el mediojuego, Caruana cerró el centro con el movimiento d4-d5 y y la partida se agudizó bastante. El juego de Fabiano se desarrollaba por el flanco de dama mientras que Veselin intentaba crear accesos por el flanco de rey con la ruptura f5. Con ambos apurados de tiempo, Topalov se equivocó y metió la pata. Era una posición tan ganadora que el punto para el norteamericano era la conclusión que se anticipaba. Sin embargo, Caruana cometió un error garrafal y era el movimiento 41. La victoria ya no era tan aparente y en el final de torres, la partida terminó en tablas. Un resultado de infarto para Fabiano y una pausa bastante favorable para Topalov.
