25NL, 2 hands, stupid river and weird betting

[spacetime]

1) Going off memory, didnt save HH. UTG seems like he plays a bit too many hands, only been here a few orbits, I have been cbetting a lot, RR him and another player PF. Not sure how he has his stack, I was opening a few tables and didnt notice it. Ultimate Bet...

Hero (BB): ~30
Villain (UTG): ~40

PF: UTG limps, CO Limps, SB folds, Hero raises to $2, UTG calls, CO folds.

Flop (~4.50): 6x6[img]/images/graemlins/heart.gif[/img]9[img]/images/graemlins/heart.gif[/img]
Hero bets $4, Villain calls.

Turn (~12.50): Jx
Hero bets $10, Villain calls.

River (~32.50): A[img]/images/graemlins/heart.gif[/img]
Hero checks, Villain insta pushes, Hero folds. (~15 to me).

Hand 2 Villain is 32/2 over small sample, CO was like 50/44 hence raise.

What are your cards in hand 1?

Hand 2 I don't think I can fold there given such good odds, but it does look like you are probably beat.
Also, what are the stack sizes here?
