The geometry of a tree exactly describes what happens when you play a game with specified rules. Even though games like checkers, or m which is a sort of like very small skel game, or tick tak to, or connect for or ia forgott, those are all obviously games with different rules but they have the same kind of rules. And that's why, if you know, for instance, a modern a machine learning engine, a essentially doesn't care which game it's learning. It's not built to learn go. It's built to learn how to play well a game with any set of rules of a certain kind.
