    I am curious if someone know of a way of modeling/interpreting the game Go as a category. I can't seem to find anything when doing an online search but that probably has something to do with the name of the game being such a common word. (Go is such a favorite math game that someone must have done this, right?)

    I can see that it is possible to call objects of such a category all the board positions possible and morphisms being a kind of "subset" relationship between the different board positions. For example, if a specific board position, a, can be arrived after a specific board position, b, then define a morphism b -> a. (This way we can satisfy the associative property required for a category and we just get a semi-lattice.) However I am really curious if there is another way of looking at the game categorically.

    (New to the forum here, hello everyone! I hope this is the right place to talk about such things. I am If not then sorry for the "spam"!)

    Possible F. Honsell et al.’s ’Categories of Coalgebraic Games’ has something relevant. It discusses game operations used by Conway to analyse games such as Nim and Go.
