NL100 - AK, i messed up somewhere

[RedBarracuda]

CO is an old school fish/calling station whom I don't care about since he plays 90% of his hands by calling..

Villain is 35/15 / 6.12 / 17% / 27% over 300 hands.
So, he's spewy but also weakish (17% WtSD) but that's probably because he is so aggressive he didn't have a chance to get to many showdowns. That's also the reason I bet less against him, because I find it that against WT players, smaller bets take the pot often enough. I don't know what I was thinking by the time the tunr card came, but i called his miniraise on flop to reevaluate on turn. I've seen him PFR from the BTN with AJ and when he gets a call from a SB and flops top two he bets a bit under 1/2 pot and then again the same on turn. It looks like he is the "milking type" and I am unsure if i am ahead here because at this point I am not beating much. I dunno what I was supposed to do. What should I have done?

I would have folded on the flop. But as you describe him here this looks like a "milking type bet"

What are you beating on the flop? He called from the BB at a discount so he could have anthing here 2pr, set, straight. Easy fold!

It's hard for your hand to improve vs. anything he might already have and he's charging too much for it anyway. I say save the bullets for another fight, It's your button next.
