[Diagram]
An incomplete eye in the center

The diagram shows an incomplete eye in the center. If White manage to occupy two (or more) of the corner points marked x, then this will become a false eye. The two diagrams below are examples of false eyes.

False eye #1

False eye #2


Evpsych: I don't get this rule, although it is correct. Why are corners special? It seems to me that any 2 of the 8 points that form a square around the eye will "falsify" it. Perhaps others are as confused as I am about this.

unkx80: Maybe because if White occupies any of the four non-corner points, then the Black stones will not surround a point, so it should be obvious that there is no eye there. I think this is used for differentiating between a real eye and a false eye.

Evpsych: It might be worth pointing out the rationale in any master edit.


For a more detailed discussion on real eyes versus false eyes, please see the recognizing an eye page.

More formal definitons are attempted at eye definition discussion.
