[Logik]

PokerStars No-Limit Hold'em, $0.25 BB (5 handed) converter

BB ($10.20)
Hero ($25)
MP ($8.15)
Button ($26.90)
SB ($31.50)

Preflop: Hero is UTG with Q[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/heart.gif[/img].
<font color="#CC3333">Hero raises to $0.75</font>, <font color="#666666">3 folds</font>, BB calls $0.50.

Flop: ($1.60) 2[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets $0.75</font>, Hero calls $0.75.

There are no draws whatsoever. Rainbow. I am very, very, very ahead at this point

Turn: ($3.10) 4[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets $1.25</font>, Hero calls $1.25.

I was considering bumping it to $3 here but I didn't want a lower pocket pair to get away that easily. There is a flush draw, and I am slightly scared of it but not really.

River: ($5.60) 8[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets $2.25</font>, Hero calls $2.25.

Oops. Flush card hit. He has $5 left. Do I tap him?

Final Pot: $10.10


I didn't have to many hands against villian, but he hadn't gotten out of line. Should I have pushed the river? He played a flush a couple orbits ago in a similar manner.

BB had ~$5 left after the river bet.
