Dead

    Keywords: Life & Death

A group is dead when its owner has no sequence to make it live with two eyes or in seki. It is the complementary concept of status to alive; but at any moment there may be several unsettled groups on the board.

If your opponent's group is dead, you have succeeded in killing it, but not yet in capturing it and taking it off the board. That you may have to do, when one of your own groups is attacked; for the most part you don't want to spend plays capturing dead stones if you have a choice.

The method of capturing a dead group may involve plays inside the group, requiring the method of playing inside systematically, also known as attrition method because several plays inside may be required to remove one net liberty.


The correct way to carry out the attrition method is part of the theory of nakade; see almost fill. Mistakes are possible.

See also the Eyes Collection.


The definition is rather weak and examples would be nice on this page.
