Equivalence Scoring and Ikeda's Rule
Ikeda's Rule and Equivalence Scoring can be combined in a very convenient way:
- If White passes and no one passed before then this pass is free and requires no pass stone.
thus we gain:
- all advantages of Ikeda's Rule[1]
at the cost of
- requirement to determine the score by counting territory and prisoners.
- use of typical territory komi (1 moku less than area komi)

[1] To behave exactly as Ikeda's Rule does, it would also be necessary that the first pass does not count as one of the two alternation-ending passes. - Pledger
