Zhou Junxun of Taiwan wins international LG Cup

Wednesday, March 21st, 2007
Taiwan is catching up with the top 3 Go super-powers: Zhou Junxun 9p of Taiwan just won the 11th LG Cup international tournament. He defeated in the final match Hu Yaoyu 8p of China, 2-1. While several Taiwanese born players moved to Japan as kids, became insei and then became top professionals in Japan, this is the first time that a Taiwanese trained professional had such a great success in an international title. There is an old article about Zhou Junxun’s earlier Go career at Mindzine. The first game of the final match is commented at – it is one of the several free sample commented games. After Zhou Junxun won the first game by resign, the next 2 games were very close: both were half-pointers. Here is a diagram from the last game:

Black (Zhou Junxun) ended up sente in the complicated joseki in the lower left, so he invaded the upper-left corner in sente, and then played tengen to reduce White’s central influence. A fight started as White invaded Black’s moyo on the right soon after this.
