Basic Ko Rule

    Keywords: Ko, Rules

The basic ko rule prohibits immediate recapture of a single stone that has just captured a single stone, as in the diagram below


B1 captures white+circle, W2 captures B1 illegally

This rule does not prevent longer cycles. Different rulesets have different rules for dealing with longer cycles, but all rulesets prevent basic kos.[1]

[1] Robert Pauli: Well, "Natural" Situational Superko not always.

RobertJasiek: Basic ko is a terrible (page) alias for basic ko rule because a basic ko is a ko (shape) to which a basic ko rule might apply. The alias hides the term "basic ko", which is NOT the basic ko rule.

RobertJasiek: Herman, you have created a BasicKoRule alias but the BasicKo alias persists. What is your intention?
