False Eye

A false eye is something which possibly looks like an eye, but really isn't an eye. Usually false eyes involve diagonal connections.

It fails the second condition stated in the recognizing an eye page.

[Diagram]
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 in atari. If Black connects at a obviously the "eye" disappears. If however Black allows White to capture the two stones the "eye" is also gone.

Thus, a false eye is not an eye.

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 WC stone is a throw-in, a technique commonly used to destroy eyes.
