UTG calls $1, <font color="#CC3333">Hero raises to $5</font>, <font color="#666666">3 folds</font>, BB calls $4, UTG calls $4.

Flop: ($15.50) 3[img]/images/graemlins/spade.gif[/img], 2[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">BB bets $7</font>, UTG calls $7, Hero...

UTG is fish. It's likely he has flush draw or a Q here, maybe 45. Not sure what to make of BB's bet. I'm sure I can string UTG along if turn blanks. Raise? What do I do if BB 3bets? Call and bomb blank turn?

Raise to like 35. What to do if BB 3-bets is very read dependent, but it's probably a fold if BB is a solid player.

He's an unknown.

Eh, I probably get it in against an unknown for one buyin on this flop, but I tend to be a bit of a calling station.
