AJ missplayed turn??

[Steve09797]

I just sat down at the table, but have some history of villian. He is 15.4 VPIP, 4.6 PFR, and zero aggresion. It' only on 57 hands, but this makes me think I should have either folded or pushed on the turn. The only thing I was thinking is he might have flopped a set.
Even my flop call is questionable. I apprciate any advice.

I think I lay this down to the flop raise, and certainly to the turn bet. Given his stats you haven't seen much postflop aggression and now suddenly he's aggressive, I don't think your ahead enough here to keep calling down.

What about a reraise on the flop? Think i might have bet the turn too. He doesn't seem too confident on the river.

can you put him on overcards here though, and go all in?
