First of all, no matter what you do you arent showing him your hand. I am assuming villain is an idiot for making the bet size the way he did so I doubt this guy is a master of hand reading. With that said, I am probably just going to flat this flop. There is nothing to protect against and he could pretty easily be doing this with a 7, but he could also be doing this with any pair. I dont want to scare him off any of the random holdings he has so just let him bet into you again on the turn. By that point you can decide from the board texture if you want to shove over his bet or just flat again but Im leaning towards shove.
