Position play

[kurto]

Villain is a LAG with the name of theivingf*k. I think that tells you a lot. (I don't usually share names but I thought it important here) Raising a lot from any position with any PP, any 2 suited, etc. More cautious postflop.

UTG+1 ($31.4)

MP2 ($32.65)
MP3 ($23.55)
CO ($44)
Hero ($28.4)
SB ($25.25)
BB ($17.55)
UTG ($25)

Preflop: Hero is Button with 4/images/graemlins/diamond.gif, A/images/graemlins/diamond.gif. SB posts a blind of $0.1.
<font color="#CC3333">UTG raises to $0.75</font>, <font color="#666666">1 fold</font>, MP1 calls $0.75, <font color="#666666">3 folds</font>, Hero calls $0.75, <font color="#666666">2 folds</font>.

practically a min raise... I've got position, why not, right?

Flop: ($2.60) K/images/graemlins/diamond.gif, 3/images/graemlins/heart.gif, 2/images/graemlins/heart.gif <font color="#0000FF">(3 players)</font>
<font color="#CC3333">UTG bets $0.5</font>, MP1 folds, Hero calls $0.50.

$.50 into a $2.60 pot? I should have raised. Beyond that, a fold is out of the question, right?

Turn: ($3.60) J/images/graemlins/spade.gif <font color="#0000FF">(2 players)</font>
UTG checks, <font color="#CC3333">Hero bets $2</font>, UTG calls $2.

There's no way I can't now bluff this down to the river, right? I guess the question is how much to bet. I wanted to make my bet seem like a value bet and not a bluff.

River: ($7.60) 9/images/graemlins/spade.gif <font color="#0000FF">(2 players)</font>
UTG checks, <font color="#CC3333">Hero bets $5</font>, UTG folds.

Here again... is there a magic number that looks like a value bet and not a bluff? I thought 2/3 pot spoke of confidence value betting.
