I think I’d call. I mean, it’s easy for him to scare you off your hand now. If he has an ace, I’ll guess he’d act a little bit discouraged by the flop and check, hoping that you’ll call him “light” on a later street. And if he has QQ or JJ, KQs, or 88 or I don’t know, now is the perfect timing to make you fold your kings.
on the other hand, it’s true that villain 4bets. Does he do it often? Could he 4bet light? What would his range be? Not sure after all, not that easy of a spot.
Oops! How did that happen? Well, he has to bet 100% of his hands at some point since you exposed. The question is, which hands would he jam the flop with? He also will not be expecting you to bet if he checks to you. How fast did he jam? I think I have to call, all things considered. Probably a coin toss.
