Hi, 4th World Go Meijin Competition was held 3 days ago, and Chen won by half point. It was played on Chinese rule, but if it were on Japanese rule, Chen would have lost by half point. It is because Japanese rule does not count territory in seki.
I wonder it is maybe interesting KGS 9x9 tournament in Japanese rule, once a year. 19XXXX.........XXO... 18OXOXXO...O..XXO.... 17OOOOX...XXXXXOOOOO.
