What's the logic behind NSSK? [#2359]
18.104.22.168: What's the logic behind NSSK?
(2010-08-20 23:22) [#7895]
As I see it, PSK is the simplest way to prevent cycles, SSK allows more possibilities, and NSSK allows even more, but how does this strictly prevent cycles? Does it have to do with two-pass endings?
: logic behind NSSK [natural situational superko]]?

To be honnest I don't know.
My guess would be it is to allow as much as possible. (so that the superko rule prevents as little as possible.
you can see the progression
- positional superko prevents the most
- situational superko allows more
- natural situational superko allows a bit more
- Repeat of moves (in the same position the same player may not make the same move) allows even more.
I think Repeat of moves is the most allowing superko rule that is possible while it still will make sure a game will always come to an end. (but it can take much longer)
There is a discussion if it all makes even can make a theoretical difference.
