Editing Life and death (section)

==Caveats==

Groups that are ''alive'' may yet die. One reason is that they may be sacrificed, in the course of a [[ko fight]].

Another way in which the ''ko'' rule enters the discussion is through the complications ''ko'' adds to the classification by status. It is quite possible for a group to be alive in ''ko'': that is, the group is ''conditionally alive'', the condition being to be able to win a particular ''ko'' fight relating to the control of a key intersection.
