Both hands below vs. the same Villian. Comments on the laydowns would be most helpful.

Hand #1: No read on Villian yet. Can't really think of anything besides AK that would take Villian's preflop line that I beat. If I call his flop bet, I'm tied to the pot.

Hand #2: A little later in session. I've seen Villian push flops with very marginal hands with mixed results...getting snapped off and called by worse hands, so it's been pretty breakeven for him. Also seen him make a few untimely river bluffs. Loose and aggressive play overall, but not very good.

I don't think I like my turn play much, but I can't really put my finger on where I went wrong...

1st fold is terrible.
Raise preflop much more, probably to $8 or so, then get it all in on that flop everytime. You dont think he lays AQ or QK like this? Way overestimating a typical NL25'er (from what I've read) in my opinion.

2nd hand I think the turn is a check is in order most of the time, he's drawing to 6 outs if we give him the free card or its possible we're beat already. This is why being OOP sucks. If I'm bet I'm sure as hell not betting less than half pot, that is pretty much screaming "I have no hand please raise me."

Hand #1 is absolutely horrible. Don't ever fold that.

Hand #2 I think you should checkraise if you're confident he's that bad and calling with a crappy draw, or check/fold. He might scream "POT ODDS!!!!!!" if he bets $6 on the turn and you push him all in and he holds a crappy pair + draw.
