100/200 hand: good, bad, ugly?

[Fianchetto]

100/200 B&M full game, my image is pretty tight at this point.

Tight aggressive player raises UTG, I 3-bet UTG+2 with A [img]/images/graemlins/heart.gif[/img] A [img]/images/graemlins/spade.gif[/img], folded around to UTG who calls. We're heads up.

Flop: 3 [img]/images/graemlins/heart.gif[/img] 4 [img]/images/graemlins/diamond.gif[/img] 8 [img]/images/graemlins/club.gif[/img]

He checks, I bet, he calls.

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

He checks, I bet, he raises, I call and plan on raising almost any river card except probably a K.

River: 6 [img]/images/graemlins/diamond.gif[/img]

He bets, I raise, he 3-bets....now what?
