AQ in BB vs TAG

[jskills]

Vilann is TAG - as is everyone now on Empire.

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

Flop: (4.50 SB) K[img]/images/graemlins/heart.gif[/img], K[img]/images/graemlins/club.gif[/img], 7[img]/images/graemlins/spade.gif[/img] <font color="#0000FF">(2 players)</font>
Hero checks, MP2 checks.

Turn: (2.25 BB) Q[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">Hero ?</font>

Looking for a plan here.

I lean towards betting, but if we get raised do we suspect a AK or AQ? And then what?
