AA raised on riv line check pl0x

Vil's a 22/14 2AF, 6% 3b over 500 hands. I've been pounding him quite a bit pre and postflop up to this hand but haven't shown down much so I'm unsure of his bluffing frequencies. I saw him call down light for stacks in a 3b pot.


SB: $176.00
BB: $145.15
Hero (UTG): $695.40
CO: $244.75
BTN: $400.30

Pre Flop: ($3.00) Hero is UTG with A A
Hero raises to $7.00, 1 fold, BTN calls $7, 2 folds

Flop: ($17.00) Q T 2 (2 players)
Hero bets $12.00, BTN calls $12

Turn: ($41.00) 8 (2 players)
Hero bets $32.00, BTN calls $32

River: ($105.00) 7 (2 players)
Hero bets $82.00, BTN raises to $349.30 all in, Hero folds



This seemed like an easy fold at the time but I'm not so sure now and am having a pretty hard time putting him on a hand. I would assume he'd look to raise the turn with TT/22/QT/J9, though he could've been banking on me barreling on the river. So, I dunno. What do you guys think? Anyone play this differently?
