I quite liked this, though I wonder if the metaphorical aspects of the match do not translate well to the reader who is not versed in the fundamentals of Go at least. The issue of ko moves made during a sealed play, for example, plays a crucial role in the climax. It's also very interesting to note how Go theory has changed over the years, and how moves that were radical then are pretty much standard now. A scene where the narrator puts forward the notion that Go is essentially Japanese and that other cultures may not be able to grasp its true nature is the only thing that bothered me. Overall I found it enjoyable, immensely subtle, and moving.
