Preflop: Hero is SB with Q[img]/images/graemlins/diamond.gif[/img], Q[img]/images/graemlins/club.gif[/img].
UTG calls, <font color="#666666">4 folds</font>, MP3 calls, <font color="#666666">2 folds</font>, <font color="#CC3333">Hero raises</font>, BB calls, UTG calls, MP3 calls.

Flop: (8 SB) 4[img]/images/graemlins/heart.gif[/img], J[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(4 players)</font>

There's no point in going to war once we get heads up correct?

Hero ...

Do I continue the check/call line, or do I bet here?
I see betting the river show up in WA/WB lines a lot, but what worse hand will call me?

Or did I screw this hand up from the flop?
