I tracked down a rare hang/crash in my bot and I'm curious how others
handle this.
I use simple ko state as part of my hash lookup, but I don't use super
ko. I can't store the whole graph history because then there would be
no transpositions at all. I can't really update legal moves to exclude
super ko because the super ko legality changes based on how a node is
reached.
In particular, a deterministic algorithm like UCT can get caught in an
infinite loop. My random playouts may take a bit longer from super ko,
but it gets quickly resolved.
