UTG ($2.65)
UTG+1 ($10.03)
MP1 ($10.11)
MP2 ($1.37)
CO ($5.24)
Button ($9.17)
Hero ($5.18)
BB ($2.63)

Preflop: Hero is SB with K/images/graemlins/club.gif, Q/images/graemlins/club.gif.
<font color="#666666">5 folds</font>, Button calls $0.05, <font color="#CC3333">Hero raises to $0.25</font>, <font color="#666666">1 fold</font>, Button calls $0.20.

Button was the loose player at the table seeing the flop with over half his hands. Not rated yet with PT but will probably be a calling station as player is kind of passive post flop.

Should I be raising more than what I did since my position is bad?

Flop: ($0.55) 3/images/graemlins/diamond.gif, 2/images/graemlins/heart.gif, 3/images/graemlins/heart.gif <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets $0.3</font>, Button calls $0.30.

Bet more on the flop? I thought a bit more than half was ok but not really sure.

Turn: ($1.15) 7/images/graemlins/club.gif <font color="#0000FF">(2 players)</font>
Hero checks, Button checks.

River: ($1.15) A/images/graemlins/spade.gif <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero bets $0.2</font>

Too low? Just check? I don't think I have ever been in this spot before.

Thanks for any ideas.

I just check the river. Betting 1/6 the pot is going to get a ton of calls, especially from a hand that beats you. If villan is a calling station, he probably has been calling you down with A-high or a low-mid pocket pair.

If he calls your river bet, I don't expect to win the pot very often.

Just check.

O, flop and turn are fine btw.
