I'm a bit confused. What's the difference between "knowing everything that the best go bot knows" and "being able to play an even game against a go bot."? I think they're basically the same. It seems to me that you can't know everything the go bot knows without being able to beat any professional go player.
Or am I missing something?
Sure. But the question is can you know everything it knows and not be as good as it? That is, does understanding the go bot in your sense imply that you could play an even game against it?
