I'm reading Yuan Zhou's "Master Play: The Fighting Styles of Kato Masao and Seo Bong Soo" (which I'm really enjoying) and I came to a variation that I am not convinced of. Can you guys show me where I've gone wrong in my analysis? Here's the section from the book (From page 44):



So, I assume he means this:

That makes sense to me, but it seem like Black can connect at instead of capturing to guarantee life (now a and b are miai for life?):

What do you guys think about these sequences?

edit : removing mistake before too many people see it!

Ping. Anyone have any ideas here??

I think I can say with a pretty high amount of certainty that you are not incorrect. Black is alive as he stands. It is not really a very complicated situation after B connects at "a", so there weren't that many variations to try out.

I believe these books were put together on the basis of an oral commentary given by Zhou which was video-ed, then transcribed and edited by an amateur. So a reference to a throw-in may have been misinterpreted by the amateur - on the wrong side, for example.

Also there may be a problem with the limited English of a non-native. This game was commented in Go World 15 (this is the sort of thing Kombilo tells you instantly), and there the language is more subtle - Black 65 is "dubious" rather than a mistake, and Black fails to "secure" an eye rather than "get" one.

Thanks. I can see what you mean by an error in transcription. I really just wanted to know if I had read these variations incorrectly somehow, since my goal is to improve my reading.
