I asked about this happening to one of my friends in Korea, and he said, there was a miareading to Lee which is exchanges at atari A and B. Lee thought B should atari sometime at A, and which shortens B's two liberties. That's why he resigned here, but if he keeped playing, he should have found out the right sequence.](;)(;B[oc]C[If B keeps going,];W[na];B[ob];W[mc];B[lc];W[lb];B[kb];W[ka];B[jb];W[al];B[bl];W[ak];B[am];W[ai];B[lf];W[kf];B[km]C[B is winning the race by one liberty. There were lots of chances for B to win, but Lee missed a lot. Even when Lee resigned, the game was almost finished, and Won already knew he'd lose the capturing race. It's unbelievable that Lee misread an easy move. Anyway, Lee Chang-Ho is still the most famous and favourite player to many of Go fans, and it's such a pity we can't watch his playing in Fujitsu Cup this year. Most of Korean Baduk fans want him to be in the international tournaments without any qualifiers, and I don't know if Korean Baduk Association makes an exception for Lee. Thanks.
