Playing little 5/10 on hangover and maybe I took this line coz of that, comments?
Prima:

> SB folded
> BB checked
> Dealing the Flop(Q [img]/images/graemlins/diamond.gif[/img] 8 [img]/images/graemlins/diamond.gif[/img] 2 [img]/images/graemlins/club.gif[/img] )
> BB checked
> HERO bet for $12.55
> BB raised for $30
> HERO raised for $34.90
> BB raised for $40
> HERO folded
> BB mucked
> BB wins $140.45

Point on this play I have never played against this opponent, so if I call his raise I have to call decent bet at least on turn, now when I raise I get free turn if he calls, and if he raises im 99% sure he has at least two pairs.
