Flop situation against a LAG

[jrobb83]

Opponent is vpip 53% pfr 34% after 52 hands and is aggressive post flop.

Party 10/20 4 handed

I openraise 7[img]/images/graemlins/spade.gif[/img]7[img]/images/graemlins/diamond.gif[/img] on the button and are called by LAG in the BB.

Flop: Q[img]/images/graemlins/spade.gif[/img]9[img]/images/graemlins/heart.gif[/img]6[img]/images/graemlins/club.gif[/img]
LAG bets, I...

And if I don't fold, what's my line of play throughout the hand?
