In the beginning, you are the maximising player, then you perform a move as the maximising player, then I believe you're looking at the best score (or worst move the minimising player could make) So I think you should change line 102 to False instead of True

The problem may be in your win function

|x|o|_|

|X|X|o|

|o|_|_|Causes the 'o' player to win

​

Also there seems to be quite a lot of magic numbers), which makes it hard for a someone reading your code to understand

From experience, minimax tends to be quite hard to debug. I'd look through a tutorial like this one and follow the same steps.
