Vesa: Indeed, it is strange to see the leftover ko - it reminds me of that famous incident involving Go Seigen, when he refused to fill in a ko (to avoid a half point loss) invoking the fact that the opponent has no ko-threats. And then, when he was told that the Nihon Ki-in rules state that a ko should be closed, he said he's not a Nihon Ki-in member. In this case I'm not sure what happened. I just checked, and the 3.5p win for Cho (which is the official score) is without White defending. Maybe it was because not only Black has no ko threats, but also White can eliminate the double ko by capturing from above? Maybe we should ask Robert Jasiek, the Go rules guru.

No one has mentioned the odd two-step ko that was left unfinished in the end though? Luckily the result didn't depend on that one. Hi Sorin, I enjoy your blog quite a lot.

The next match will be very interesting. But I think Yamashita would defend his title, but who know. Cho played great in this game. The next match will be very interesting.
