hyperactive position
Keywords: Ko
Hyperactive is a term coined by Prof. Berlekamp.
A hyperactive position is one whose count depends on who is komaster. Examples: Approach ko, Ten thousand year ko.
A ko whose count does not depend on who is komaster is called placid.
- Karl Knechtel: Why say "hyperactive position" rather than "hyperactive ko"?
- Bill: There are hyperactive positions where a placid ko is threatened.
(Later.) See Some Endgame Problem 4, where no ko is actually played.
