NL Noob Questions 2 hands

[Bona]

Very new to NL. Played 3-4 hundred hands at .01/.02 but took the advice of a forum member and went to .05/.10 to at least try to play against players who were conscious. Now have played only about 400 hands at .05/.10.

The same villain in both of these hands and he had me pretty buffaloed so I know I screwed them up. Thats my first question. How should I have played these hands?

2nd question is how to play against this type of villain. Over 90+ hands he ran 26.7/26.7/7.2. He wasn't "fit or fold" as it might look and I don't think he was running hot but he was big winner at the table because he was winning a lot of pots with pot size bets on the flop and/or turn. I never really saw him come to showdown light but he had to be betting and raising light on the flop and turn with some frequency (I think) He was 3rd seat to my right. I didn't have a lot of trouble with the other players in the game but I did with this guy. My guess is he is a better player than the others at the table and was exploiting us but my suspicion is there is a way to play a guy like this and exploit him. What say you?

I was totally lost in this hand and called him down but I'm sure I should have played it differently. But how?

I wasn't as lost in this one (I don't think [img]/images/graemlins/grin.gif[/img]) But was I OK to draw here? and I checked the river hoping to trap him but alas [img]/images/graemlins/confused.gif[/img] He curbed his aggro tendencies. Any clues you guys can give me will be appreciated. Thanks in advance.
