eye status
A group is said to own a number of eyes equivalent to the number of individual eyes that can be formed if desired. If there is a half chance of making an eye then that is counted as one half-eye. The black group in the diagram has an eye status of two made up from the one and a half eye shape in the corner and the half eye shape on the side. The eye status of the black group is verified by the miai options for Black. If White reduces Black to one eye in the corner, by playing at A, Black will promote the half eye at B by playing at C. On the other hand, if White plays at C making B a false eye, then Black will play at A to make two eyes. |
