so if you know your opponent has nothing but also know that he's prone to c-r you when he doesn't believe you, then you should check behind

Uhhhhh.... if you could see his hand, then the optimal play for you would be to bet for value, if he C/Rs you, you can call to induce bluffs on later streets or RR AI for value, depending on the situation.

Checking with AK when you know you could have the best hand is a mistake according to the fundamental theorem, but it is a smaller mistake than betting, and having to fold the best hand to a semibluff raise by our opponent.

I think it isn't bad to check AK sometimes, but mostly with the intention of giving up (on wet boards, 78T, etc). 23T I'm betting there 80% in position with AK.
