Terri Schurter I have a question about this problem. It says that there are two half eyes and one full eye. I can see that the inside group can tenuki and live, so I suppose that this must be so. If there were three half eyes it could be killed. But I look at the full eye and there are only two shoulders controlled by the center group. Isn't an eye in the center of the board controlling only two shoulders a half eye?

Darrell Malick Hi Terri,

Good question. The eye in the center is a full eye because it controls two shoulders and has miai for the third shoulder. If the Black takes one, then White will take the other maintaining the eye.

Terri Schurter Thanks. I thought it might have something to do with the two half eyes.
