10/20 NL, 3 handed...TPTK in position

[whitelime]

3 Handed 10/20NL on Prima. Villain just sat down on the table so no real reads. I've seen him before so he's most probably a decent TAGish player.

He has $2k and I cover.

I am dealt A [img]/images/graemlins/diamond.gif[/img]J [img]/images/graemlins/diamond.gif[/img] on the button.

I raise to $70. Villain calls in BB.

Flop comes J [img]/images/graemlins/club.gif[/img]2 [img]/images/graemlins/heart.gif[/img]6 [img]/images/graemlins/club.gif[/img].

Villain checks. I bet $120, he raises to $290. I call.

Turn 4 [img]/images/graemlins/heart.gif[/img]

Villain bets $600. I ?

What is the best standard line to take in this situation to maximize my EV against a player who is probably a TAG.
