If we are not honest with ourselves, the door is wide open to cheating anyway.
@terrific Regarding the second problem: What if we have simultaneous games, and some of them have the same openings, and in some we are W and in some we are B. So, we get to see both sides of a move. Are we not supposed to play any other games in case we stumble upon the same opening?
For example, if you play X move and opponent responds with Y move that you hadn’t thought, then in your game where your opponent played X move (rest of the goban is coincidentally the same) you get to play Y move, because you can’t unsee how right it is now.
I understand the issue here is AI, but what about reviewing the game with a stronger player (which I understand it’s a bit rare in our OP’s case ) who would also explain the if’s and what’s of certain moves, that AI doesn’t do. In my eyes, actual teaching would be more “cheating” in this case.
However, keeping in mind all that I have mentioned this far, when I’m in doubt that I should do/ keep something, however vague the advantage is and even if nobody knows, unless it hurts me in some way, I let it go.
So, if it takes away from your enjoyment, although it is not technically cheating, maybe don’t review that game. However, don’t paint yourself in a corner and end up restricting here and there because there is some corr game that might give an advantage.
Life doesn’t work that way and realistically you will play games, study and come upon new things every day.
AI raises the blood pressure when mentioned in relation to Go, and IMHO it leads to some overreactions. If you had framed the question “Can I study my game with 5 pros in a cave with no power for 2 months?”, I suspect some would not see it equal to cheating, because for some reason AI is always cheating.
