NL200 - Fold Trips to Aggressive Betting?

[KipBond]

$1/$2 Live - 8 players - Villain sat down 40 minutes ago. First 20 minutes he folded every hand. Next 20 minutes he's played about half of the hands, somewhat aggressively pre/post flop. None of them have been shown, though.

I'm in the BB w/ 8[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/heart.gif[/img]. EP limps. Villain in MP raises to $10. I call. EP folds.

Flop: J[img]/images/graemlins/spade.gif[/img] 9[img]/images/graemlins/diamond.gif[/img] 7[img]/images/graemlins/spade.gif[/img]

I check. Villain bets $15. I call.

Turn: 9[img]/images/graemlins/club.gif[/img]

I check. Villain bets $35. I call.

River: A[img]/images/graemlins/spade.gif[/img]

I check. Villain bets $80. What do I do??

I know I misplayed the turn, here, but as played, what should I do on the river? What range of hands should I be putting the Villain on?

Yes, fold. He either filled up with AA or hit his flush. I can't imagine he triple-barrels here and he's certainly not value betting anything like a whiffed AK or even an AJ.

So what range of hands do I put the Villain on?
Flop:
AA-77; AK-AT; Ax(spades); Kx(spades); T8 (maybe)

Turn:
Would he bet the flush draw here? I think he'd check to a get a free card. And that 9 is a bit of a scare card to most hands... Now I put him on: AA-JJ; 77; AJ

River:
Major scare card, but he still bets. Did he hit a flush with Kx(spade) in his hand? Or maybe he's betting AJ? He can't have KK-QQ. So he has: AA; JJ; AJ; Kx(suited)[unlikely]

I can beat AJ, but not AA or JJ.

How's my analysis? If it's good, wouldn't I call since it's more likely he has AJ than AA or JJ?
