It's early, so I don't know much about the villain, but I suspect he's very loose.

Yup, you need a read to continue with this hand because you're going to have NO IDEA what to do on 92% of flops So, fold.

the min raise followed by a giant 4-bet reraise is AA so often it makes me want to puke.

why these players think this move is good, i couldn't tell you. but if he's doing this without AA, you'll start to notice a pattern in how often he does it. if he min raises and 4-bets big every time he gets 3-bet, then he's full of it. if he doesn't do this often, then he likely has a big hand whenever he does.

Either way, that's read dependant. so go with the read you have: the min raise/giant 4-bet move is AA far too often for you to put ANY more money in here with JJ.
