I have no reads for Villian, which is to bad. I've seen him showdown 2 hands A6o and AJo both were A high and were no good.

Preflop: Hero is MP2 with Q[img]/images/graemlins/club.gif[/img], K[img]/images/graemlins/diamond.gif[/img].
<font color="#666666">2 folds</font>, MP1 calls, <font color="#CC3333">Hero raises</font>, <font color="#666666">4 folds</font>, MP1 calls.

Flop: (5.50 SB) 2[img]/images/graemlins/spade.gif[/img], Q[img]/images/graemlins/heart.gif[/img], Q[img]/images/graemlins/diamond.gif[/img] <font color="#0000FF">(2 players)</font>
MP1 checks, <font color="#CC3333">Hero bets</font>, <font color="#CC3333">MP1 raises</font>, Hero..?

What is my line here? 3-bet the flop or call and pop the turn? Explain.
