Villain is 8/3 Agg factor 1.7 3bet 3% over 120 hands.

At this stage I'd be seen as 17/13 Agg factor 2.8

PokerStars No-Limit Hold'em, $0.10 BB (8 handed) - PokerStars Converter Tool from FlopTurnRiver.com

Button ($10)
SB ($5.26)
BB ($10.15)
Hero (UTG) ($17.90)
UTG+1 ($4)
MP1 ($10)
MP2 ($9.70)
CO ($12.02)

Preflop: Hero is UTG with A, Q
Hero bets $0.40, 4 folds, Button calls $0.40, 2 folds

When villain calls I put him on 22-JJ, AQs+, AKo. I discount QQ-AA as I think he would raise those and I don't think he'd be calling with less.

Flop: ($0.95) K, 10, 5 (2 players)
Hero bets $0.55, Button raises to $1.50, Hero calls $0.95

Decide to bet with gut shot and figure he'd be folding 22-44, 66-99 and maybe JJ and AQ if he doesn't have the FD.

After his raise I'm thinking he has AK or possibly AcQc.

With the gut shot I call with the intention of folding if I don't improve on the turn.

Turn: ($3.95) A (2 players)
Hero checks, Button bets $1.50, Hero calls $1.50

Ok, so I improve but by my reckoning I'm either crushed by AK or possibly chopping with AQ. I decide to check as I now have showdown value but not much more.

His bet is a strange sizing to my thinking. Seems to be giving me pretty good odds for any draws I might have. It did kind of feel like this was more likely to be AcQc and he was double barrelling because of his increased equity. I call figuring I'd see the river and see what he does.

River: ($6.95) K (2 players)
Hero checks, Button bets $6.60 (All-In), Hero folds

Ok, that seals it to my way of thinking. FD completes, AK already had me crushed anyway so c/f seems my best option.

Thoughts?
