Editing Life and death (section)

=== Eyes and false eyes ===
Liberties inside a group are called ''eyes''. In the previous example, '''a''', '''b''', '''c''' and '''d''' are eyes. An eye may be a single empty intersection, or more of them. In the diagram on the left, the intersections marked '''e''' form a single eye, and '''f''' forms another eye. The group has two—separated—eye spaces. Even though white can make a move in these eyes, black could eventually capture the white stones, and each eye would thereby be reduced to a single intersection.

An inner liberty where the opponent can still capture part of the group that encloses this liberty is called a 'false eye' or 'deficient eye'. A group with only one eye is not alive. In the example on the left, white can play at '''g''', and capture a black stone. That eye is then destroyed, and black has only one eye left, so that group is now ''dead''.  The black group at '''g''' is dead, because it can not form two true eyes.
