Hu Yaoyu contra Lee Chang-ho

La siguiente partida se dará en la primera ronda de la 11º Samsung Cup entre el coreano Lee Chang-ho y el jugador chino Hu Yaoyu.

Lee Chang-ho ha sido considerado el jugador más fuerte entre el 1996 hasta el 2005, año tras el cual no ha vuelto a conseguir el título de la Samsung Cup. Como ya dije, esta partida es de la 11º edición, en la cual acabará llegando a la final pero pierde contra Chang Hao por 2-0.

De Hu Yaoyu no tengo mucho conocimiento, sólo puedo decir que ha ganado diversos títulos y creo que continua como 8p.

La partida que jugaron entre los dos y la tengo en el ordenador comentada (tal como dije que tenía partidas aquí):
