if he had a hand as strong as AK, and on the turn he pushes? you have to cancel that because he doesnt want you to fold here, and an AI overbet puts too much pressure on you for a limp.

the turn definitly sets off a few alarms in my mind, but i would consider your hand good and im calling here on this push, because to me it shows more weakness than strength. if he woke up w/ a set of 7's.. that sucks, reload and go back at it.. i think you made the right call.
