Admin Javier Publicado July 24, 2012 at 05:05 Admin Share Publicado July 24, 2012 at 05:05 Os pongo las 3 primeras partidas del torneazo de Biel con comentarios... ¡en inglés! El caso es que las he anotado en inglés primero y la verdad es que me da bastante pereza anotarlas también en Español. Pero bueno, los símbolos están todos en internacional y además la mayoría sabéis bastante inglés. Así practicamos un poco, que con el paro que hay a ver si al menos vamos siendo más competitivos en idiomas también. La primera ronda fue muy interesante. ¡Tanto Giri como Morozevic omitieron un sacrificio de dama! (seguramente estaban bastante apurados de tiempo). La victoria de Hao fue más que impresionante.

Chicho Terremoto Publicado July 24, 2012 at 07:55 Share Publicado July 24, 2012 at 07:55 Ya puse que Wang Hao puede dar mucha guerra. Me sigue pareciendo Carlsen favorito pero Wang Hao para mí creo que tiene muchas opciones de quedar 2º. Error gravísimo de Morozevich que al final le costó la partida, la verdad es que no es muy complicado, imagino que estarían cerca de los apuros de tiempo, sino no tiene explicación.
