As much as we love to believe these ppl are capable of getting out of line here, on average they aren't. They probably think they are getting out of line by doing this with AK, cause they don't even have a pair yet pre-flop.

If you want to continue, I suppose I can see a call, but I think it should be a turn fold. Flop check is fine imo. I'd imagine his preflop range is like TT+, AK and maybe some AJ/AQ.

Honestly given stacks, if I really didn't believe him I might re-pop sometimes pre with this particular hand (good blockers etc). I think re-popping puts a ton of pressure on him, even with hands like JJ-KK.
