AQs headsup against a TAG reraise

[McNeese72]

Okay time to post a few hands.

Villain is a definite TAG. Tell me if I should have played this differently. I'm posting my thoughts after the hand.

Pre-flop: (9 players) McNeese72 is UTG+1 with A[img]/images/graemlins/heart.gif[/img] Q[img]/images/graemlins/heart.gif[/img]
UTG calls, <font color="#cc0000">McNeese72 raises</font>, 3 folds, <font color="#cc0000">CO 3-bets</font>, 4 folds, McNeese72 calls.

Flop: A[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/spade.gif[/img] 8[img]/images/graemlins/spade.gif[/img] (8.5SB, 2 players)

Turn: 7[img]/images/graemlins/spade.gif[/img] (5.25BB, 2 players)
<font color="#cc0000">McNeese72 bets</font>, CO calls.

River: 5[img]/images/graemlins/club.gif[/img] (7.25BB, 2 players)
McNeese72 checks, CO checks.

Pre-flop, with the 3-bet he probably has a high pocket pair.

Flop, despite the monotone flop (not my suit) and with top pair and good kicker, I'm probably ahead. I lead out and he just calls.

Definitely didn't like the fourth spade falling. I led out representing a spade incase he didn't have one. When he just calls, I figure he has one.

After the river blank, I check intending to fold to a bet.
