I do not understand this example. Is this an actual game? The major problem I have with it is that there is one more White stone on the board than Black, yet the only place I see where something could have been captured, Black would have done the capturing. Huh?
So you took the time to post here but did not simply click on the link and check the diagram in the original publication? Hmmm... Anyway, good counting the stone at M13 in the original diagram here should not have been there. Fixed. Dave
