AJ - is my line ok? standard?

Villian is 57/7 but it may seem like I am getting out line as I won a few pots recently.
I also only raise 3x bb now + 1 for limper.

How aggressive is he postflop? AF? If he's passive then I'd definatly fold the river and play it the same.

NH

looks like a $5 bet into $17 pot, when he knew you busted him with a raise on the flop...

i doubt i call the turn, unless you have a read that he will lead a draw after a raise. especially if he's aggro, it looks like a monster to me. this may sound passive to you, but i'd rather pick him off another time when i dont think i could be up against AK, a set, or worse AQ; hell, maybe a pair and a flush draw. any way you size it up, it aint good.

Is that the exact pot size ($25)?
