PP's in aggressive game

[jmumm]

I'd consider myself a beginner-intermediate level player, and I'm posting a few hands that I had a pocket pair in a rather semi-loose/aggressive game. After reviewing them, I think there's a couple bad plays I made and would like some input.

When J hits on turn, I figure its more than likely he doesn't have a J, he's probably betting w/ A high, maybe had A6s/A7s or a mid pocket pair. I'm fairly certain I have him beat, but is my river raise here -EV?



Hand 2
Villain is 28/18/2.2 after 1000+ hands and I have caught him before raising some flops with complete air when checked to.

Looking back on this, I'm really not sure why I bet the turn here. He tends to bully a lot on the flop, should I just have c/c'd the turn here?

Is c/c'ing flop and turn too weak here? I figure he's either on a big ace which hasn't hit or a big pocket pair.
