Más sobre la séptima

por Nadja Wittmann
18/11/2014 – Carlsen planteó una idea de apertura muy profunda en lo que había sido el terreno más probable de lucha, la defensa Berlinesa de la apertura Española. El sacrificio de peón había sido jugado en otras ocasiones por grandes maestros de primera fila, pero el toque que le dio Carlsen con 24.g4!? agregó una nueva dimensión desagradable para las negras.

Información adicional sobre la séptima partida

Anastasiya Karlovich, jefa de prensa de la FIDE, y Vijay Kumar, que hace reportajes para la televisión de Doordarshan, que se emite por toda Asia. Sus reportajes llegan a 400.000.000 de personas.

Anand tuvo que rumiar durante mucho tiempo cómo acabar con la iniciativa de las blancas y cómo alcanzar un final en el que no estuviera mucho peor. Su decisión valiente e intuitiva de sacrificar el alfil para llegar a un final en el cual las blancas tendrían un caballo, dos peones y una torre contra la torre negra y cuatro peones pasados, parecía ser un plan razonable. No obstante, muchos se empezaban a preguntar si la posición efectivamente estaba igualada o si las blancas iban a poder abrirse paso por la defensa de las negras. Fue imposible averiguarlo sobre el tablero e incluso la mayoría de los comentaristas estaba dudando si las negras iban a ser capaces de aguantar o no, en todos los sentidos.

Anand tuvo que aguantar durante mucho tiempo, ¡122 movimientos!

Shipov y Smirin comentando

La defensa Berlinesa no sorprendió a nadie, pero Anand tendrá que comprobar que esta línea también está a prueba de fuego durante los próximos encuentros y tendrá que intentar perfeccionarla.

Komodo 8 el módulo de ajedrez recién salido al mercado, indicaba en el movimiento 67 que la partida ya era tablas. Sin embargo otro módulo, Stockfish, incluso a una profundidad de cálculo más grande, veía posibilidades de ganar al bando blanco.

Carlsen procurando torturar a Anand

El final del día, la partida concluyó en empate tras una reñida lucha

Estas tablas han sido absolutamente instrumentales para Anand. Habría sido una tarea tremenda, perder dos partidas consecutivas y resucitar con tan solo cinco partidas restantes. El hecho de que Vishy Anand vaya a jugar con blancas tres veces en las últimas cinco partidas, hace pensar en una estrategia consistente en no perder con negras y utilizar las tres oportunidades con blancas para intentar apuntarse una o varias victorias.

El duelo sigue dominado por Carlsen, pero Anand se mantiene en la lucha, continúa encontrando recursos y está lejos de darse por vencido. Hoy veremos lo que hará Anand para devolver el golpe.

Rxh5 (23. b3 Bb1 24. Ne3 Nxe3) 23... Be6 24. g4 {The game's novelty, and a late one. The position had been reached three times in past GM games and they all ended in a draw. Carlsen (or, to be more precise, Carlsen's team) must have figured out that 24.g4 allowed him to retain some pressure.} Nd6 { Played after a five minute think, maybe Anand was recalling his preparation, but from the amount of time he was taking on his moves it is possible he was already making them up over the board. Carlsen, on the other hand, looked confident and played every move after a one or two minute think.} 25. Rh7 Nf7 ( 25... Bf7 {Is a little too passive. White has more than enough compensation after} 26. Ne3 $1 Rg8 (26... Kf8 27. Bxd6+ cxd6 28. Nf5 $14) 27. Bxd6 cxd6 28. Nf5 $16) 26. Ne3 {White's pressure is annoying. He controls the seventh rank which forces Black to keep the h7 rook out of the queenside with his knight on f7, paralyzing it. The c7 pawn is weak and has to be defended from the bishop on f4. The rook on g6 is inactive and the bishop on e6 has no targets now that it has chowed down the a2 pawn. And yet, Anand has good reasons to believe he will be ok.} Kd8 (26... Ke7 27. Bxc7 Rh6 28. Rg7 (28. Rxh6 Nxh6 {looks slightly uncomfortable for Black, but may be defensible.}) 28... Kf8 $1 $17) 27. Nf5 c5 (27... Bxf5 28. gxf5 {leaves the knight on f7 hanging.}) 28. Ng3 { Carlsen played up to this point only taking two minutes per move at the most. After 28.Ng3 Anand tanked for almost half an hour trying to figure out the position!} Ne5 (28... b6 29. Nh5 {Keeps enormous pressure.}) (28... Kd7 29. Nh5 Kc6 30. Bd2 $5 {preparing a fork on f4 also looks uncomfortable.}) (28... c4 29. Ne4 a6 30. Nc5 Bd5 31. Nxb7+ $1 $16) 29. Rh8+ {And now it was Carlsen's turn to think. He thought for about 25 minutes before he decided to go for this check. He also had a very real alternative in taking on e5.} (29. Bxe5 fxe5 30. Ne4 (30. Rh5 Bxg4 (30... Rf6 31. Ke3 Bd5 32. Ne4 Bxe4 33. Kxe4 Rf4+ 34. Ke3 Rb4 35. Rxe5 {and White's passers definitely look more dangerous than Black's.}) 31. fxg4 Rxg4 32.

Rh5 Bxg4 $1 {I think this is the best practical decision that Anand could have taken. The endgames in which he was not allowed to sacrifice his bishop already looked dangerous at best.} (31...

Rxe5 {A fascinating endgame. I had the pleasure of doing live commentary for this game with super-GM Loek Van Wely, and we both had the feeling there should be a way to crack Black's defense, but we never found one! Somehow Black kept finding interesting resources that just barely drew; most of which involved counterplay and trying to trade off the pawns on the queenside, even at the cost of all of Black's remaining pawns. Nepomniachtchi mentioned in the live broadcast that he thought this should be a draw.} b6 ( 33... Rb4 34. b3 b6 (34... c4 35. Re4) 35. Ne2 a5 36. Nc3 c4 37. Na2 cxb3 38. Nxb4) 34. Ne4 Rh4 35. Ke2 Rh6 36. b3 Kd7 37. Kd2 Kc6 38. Nc3 a6 39. Re4 Rh2+ 40. Kc1 Rh1+ 41. Kb2 Rh6 {You could say we have reached the starting point. The question here is how Carlsen will attempt to make progress. It seems that Black's only weakness is his pawn on c7, and he must target that. A rook trade is fatal for Black, so he must avoid it unless White's king is so far away that the knight and pawn endgame can be calculated to a draw. This logically means that the knight must attack c7, so d5 is a prime candidate, but things are not so easy.} 42. Nd1 Rg6 43. Ne3 Rh6 44. Re7 Rh2 (44...

Rf2 Rh4 57. c4 { Finally White commits to c4. This locks down Black's queenside and creates a stronghold for the knight on d5. Anand has two choices, he can continue without moving (by passing with his rook) or he can try to set up a c6 and b5 structure to hold.} Rh3 58. Kc2 Rh7 59. Nb2 Rh5 $1 {This move signifies the start of Anand's commitment to play b5 and c6. This particular structure will leave c5 very weak, which is why the rook is now needed on the fifth rank.} 60.

It is strikingly similar to the line that was played in the game, but with the rook on f5 things change!} Kb6 66. Nd7+ Ka5 (66... Kc7 $1 67. Rh7 Kd6 68.

Nxc6+ Ka3 $11 {White's pieces are so awkward and the king is so exposed to checks on the ranks that it does not seem possible for him to win! What a surprising turn of events.}) 68... Ka3 69. Ra7 Rg2+ $11) 67... Rg2+ 68. Kc1 Rg1+ 69. Kd2 Rg2+ 70. Ke1 bxc4 $1 {Very well calculated by Anand. He realizes that with White's king on e1 this move exactly works and he can draw comfortably.} 71.

Rxc6 Kxb3 { leads to a knight and pawn endgame that is drawn, and it was basically what happened in the game after a longer process.}) 72... Kb5 73. Rc2 a5 {White's pieces are completley paralyzed. With b3 being the only pawn remaining there is no way to untangle the queenside. The king cannot approach the b3 pawn to defend it and thus it is doomed to fall.} 74. Kf2 (74. Kd1 Rg1+ 75. Kd2 Rg2+ $11) 74... Rh3 75. Rc1 Kb4 76. Ke2 Rc3 77. Nd3+ Kxb3 78. Ra1 Kc4 79. Nf2 { Carlsen goes for a position in which he can hope to win the pawns and then go into a drawn rook and knight endgame, but one in which he can torture Anand. The rest of the game needs no commentary, Anand held comfortably.} Kb5 80. Rb1+ Kc4 81. Ne4 Ra3 82. Nd2+ Kd5 83. Rh1 a4 84. Rh5+ Kd4 85. Rh4+ Kc5 86. Kd1 Kb5 87. Kc2 Rg3 88. Ne4 Rg2+ 89. Kd3 a3 90.
