Hero has been raising $12 from HJ and on, quite a few times in the last orbit or 2.

Hero picks up AKo LJ and raises to $15 w big target in BB
Fishy Regular is in HJ and playing 100bb, he 3bets to $45(he has a portable playstation and is playing game while he grinds. Don't really know much about him. Haven't played much with him. Don't perceive him to be super knowledgeable, but probably a winning 1-3 player. Don't think he plays 2-5)

Folds to BB who tanks and eventually folds

Action on Hero.

Basically, I am unsure if villain is 3-betting a hand like AQ. Concerned his range could be like JJ+, and some AK. I don't think 4betting is really an option here because facing a jam we are pretty much always toast. We can flat here, but not knowing his exact range, and presuming it is really tight could lead us to making mistakes. I want to just fold here until I can gather more info and play more appropriately. Does anyone strongly disagree with this? Does anyone think this is just a slam dunk call, even in a live low stake setting?
