Status
   

This term goes back to James Davies' Life and Death and clarifies what one means by alive. Divide groups into three kinds:

  1. those that are alive without further plays;
  2. those unsettled groups that may live with one more play, but can be killed by a play of the opponent;
  3. those groups that are simply dead.

When determining the status of a group, we always assume alternating play. This is as simple as it can be. Complications are introduced by ko.
