False Eye
  Difficulty: Beginner   Keywords: Shape, Life & Death, Go term

A false eye is something which looks like an eye, but really isn't an eye. Usually false eyes involve diagonal connections. It fails the second condition stated in the general eye definition.

[Diagram]
Diag.: Example of false eye.

The group shown above has a real eye and a false eye. The false eye is the one at a, and notice that the marked black stone has an incomplete connection with the rest of the group.

Also when white fills up the exterior liberty at b, the two black stones are under atari. If black connects at a obviously the "eye" disappears, however if black allows white to capture the two stones the "eye" is also gone.

Thus, a false eye is not an eye.



[Diagram]
Diag.: Another common false eye.

Here's another false eye which you will encounter frequently in games. Even if the marked stone gets captured there is no real eye here for black.

The marked white stone is a throw-in, a technique commonly used to destroy eyes.



unkx80: I modified the 2/4 - 1/2 - 1/1 rule a little and moved it to general eye definition. The discussion on the definition of what is an eye and what is not has been moved to eye definition discussion so that beginners will not get scared off when they see this page.
