I think you should fold to his flop raise, he is serios, so you don't have folding equity. Even in the better case that he has Ax your AI is -EV play.

How on earth can you check behind on the flop? He'll fold most of the time to your CB, which you could make with any two cards. The fact that you have a hand here is only a bonus.

Once he CRs it's easy to fold if you decide the EV of calling or pushing is negative. Just pretend you had [4s] or something.
