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.
