AlphaGo (and, presuably, any AI system with a remotely simmilar means of operation) can output a score for each move. Actually, AG can output 2 scores: win percentage and branches explored.
You can use the relative scores to decide when to overrule the AI. Eg, if move A has a 50.1% win chance with 2k branches explored, and B has a 50.2% chance with 1.9k branches explored, I would go with the opinion of an expert human, as AG thinks the moves are essentially equal.
