Formal Definition for Basic Kos

RobertJasiek: For basic kos, a formal definition of fighting ko is available in the paper [ext] Types of Basic Ko.

Outdated Ing Approach

"A fighting ko involves repetitive removal; immediate removal of hot stones is prohibited. A disturbing ko involves cyclic removal; the disturber is prohibited from recycling."

"When life and death are not settled, repeated fighting for breaths is called a fighting ko. The ko stones in the repeating fight are called hot stones. Hot stones cannot be removed until after an interval of one board play or pass play."

Taken from [ext] Ing's Wei-ch'i Rules.
