my first thought is that if he's any good and was going for a turn c/r, he'd overbet the river with his nutted hands. 

However, he shouldn't really expect much of your range to bet on that turn, since it gives alot of your hands pair plus draw that would rather check and realize their equity/get to SD. So the turn check looks like pot control, and the river sizing looks line like thin value, making me want to raise river. if he's truly capped here, you should choose a big bet size to polarize your range. 

btw, i wouldnt worry much about your kicker; the only 4x he might have is A4s and there's only one combo

Lol @ pic

yes, raise AI. it's pretty close though; I doubt a call is losing you much EV as played

so equity. much jam.

Fold preflop you must!

PF is bad, flop is meh.

Raise / fold river.

Fold pre, call river. I think raising is really thin tbh. Hard for our hand to look like a bluff by CR'ing. I'd expect to only get called by better fours (unlikely, but there are a few) and flushes.

BOMB THAT SHEEIITTT.

then fold to a raise
