Go
Can several ko fights repeat forever, and does the rule stop it?
The rulebook mentions superko only briefly; the details come from forum discussion.

Simple ko stops only immediate recapture, so a longer cycle of positions is possible in principle. Superko rules forbid repeating any earlier whole-board position and rule it out. No single official ruling covers it, and it is rare in practice.
