China concluye en India

por ChessBase
11/03/2015 – Las cosas estaban difíciles para India al llegar a la penúltima ronda con dos encuentros de desventaja frente a China. Sethuraman siguió con su gran rendimiento, derrotando a Ding Liren, pero el resto del equipo no pudo mantener el nivel. Un desastroso rendimiento de Sasikirian permitió a China igualar la ronda 7. Y haciendo leña del árbol caído, también ganó cómodamente en la última...

Ronda 7

Video por Vijay Kumar

India igualó el séptimo encuentro contra China, manteniendo vivas las opciones para la última ronda, aunque fuese en un plano casi teórico, pues los cuatro indios tenían que ganar sus partidas.

Sethuraman continuó con su fina formam derrotando al primer tablero chino en 23 movimientos. Poco duró la alegría porque Sasikiran de nuevo desaprovechó su ventaja contra Wei Yi. Se equivocó en la secuencia de cambios en la columna d y luego fue de mal en pero hasta rendirse en la jugada 40.

Sasikirian no estuvo a la altura de lo que de él se esperaba en el equipo indio

Sasikirian has no choice but to take the rook, and although he is up the exchange, the powerful knight on d5, the passed pawn on e3 and the quickness with which the king can approach the center is enough to render his position hopeless.} 29.

Adhiban Baskaran no estuvo en forma en este torneo

Dos jugadores indios tuvieron un rendimiento fenomenal. Uno de ellos fue Lalith Babu

Nd4 Be7 {Only sixteen moves of chess, but already a position that is incredibly complicated. White has the structural advantage with a powerful passed pawn on e5, but Black's pieces are fully mobilized, more than White can say for his own, and the monarch on g1 feels uncomfortable with that pin down g1-a7. White has to be very precise to not be worse, but if he survives he would be strategically much better.} 17. Na3 $2 (17. b3 $1 {Forced and sufficient. The move is dual purpose: The first it adds pressure on to c4, which is very important, second it liberates both a3 and b2 for the dark-squared bishop.} cxb3 $1 (17... O-O-O 18. Ba3 $1 Rxd4 19.

It is trapped, and with its loss White has no chance of surviving.} 22. Qa5 Qxa3 23. Bxc6 {some clever last minute counterplay, but Black has many ways of countering it.} Bc5 (23... bxc6 24.

Ronda 8

China no dio opciones y volvió a la senda de la victoria en la última ronda, asegurando la victoria en el duelo. Consiguieron 18 puntos por tablero y 11 puntos de encuentro, por 14 y 5 de India.

Lalith Babu superó al correoso Zhou conduciendo las blancas en una defensa India de Dama en 32 movimientos.

Como en la jornada anterior, la primera victoria tuvo un corto recorrido en las esperanzas de los indios, pues en esta ocasión Adhiban perdió contra Chen Wang en una Siciliana Cerrada.

Wei Yi y Sasikiran fueron los terceros en terminar. Wei forzó a Sasikiran a optar por las tablas por repetición en 44 jugadas. Sasikiran terminó sin ganar una sola partida, cosechando 4 tablas y 4 derrotas.

Wei Yi no impresionó, pero se mantuvo en su Elo de 2700

Con el encuentro igualado a 1.5, solo quedaba disputar el honor. Sethu arriesgó contra Ding tratando de evitar las tablas con un poco consistente sacrificio de peón y lo que podían haber sido otras tablas, terminó como victoria para los chinos. Sethuraman estuvo impresionante con su 5/8 y Ding cosechó el mismo resultado para China.

Zhou Jianchao fue el peor de los chinos con un marcador... ¡del 50 %!

Los ganadores con su premio

Un gran esfuerzo de ambos equipos

Bxb4 cxb4 8. a3 {breaking with a3 soon is important: many people like to simply leave the pawn be on b4, and that always ends up back firing. The correct way of dealing with these kinds of set ups is, essentially, trading your a-pawn for the c-pawn. Meanwhile Black should fight for the dark squares.} bxa3 9. Nxa3 O-O 10. O-O a5 11. Nb5 Na6 12. Qd2 Qe7 (12... d5 $1 {Is definitely more difficult for White to deal with. The game continuation allows Lalith to binding his opponent.}) 13. Qf4 Rab8 14. Qd6 {of course. Now Black's lack of space is a real issue.} Qd8 15. Rfc1 Nb4 (15... Ne8 16. Qf4 {is playable but that knight doesn't want to be on e8.}) 16. Ne5 $1 Bxg2 17.
