It took place in the Kuksu Cup, the most important female tournament in Korea. I am Hikaru (w), Yi Cheong Won is Hong Su Yeong who is Insei in Korea. I knew my opponent very well, because we studied together in the same school.  I knew here to have a very careful, defensive style and played accordingly, but she surprised me on more than one occasion.]RE[W+1.50]
