A9s 3bet LP

[Robb]

30/60: 10 handed. My image is probably good except I had raised the previous two hands so some opponents will start to doubt my raising standards a little bit.

Loose aggressive Hijack raises, I 3bet from the CO with A [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]. SB calls, Hijack calls.
SB seems solid, no numbers on him but he's been straight forward in 2 orbits.

Flop: 2 [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/spade.gif[/img] J [img]/images/graemlins/diamond.gif[/img]
I bet SB cr's and Hijack folds. I 3 bet and SB calls.

Turn: Q [img]/images/graemlins/club.gif[/img]

River: K [img]/images/graemlins/spade.gif[/img]

Thoughts on any street?
