No reads on BB, Is anyone folding this preflop?

PokerStars No-Limit Hold'em, $0.25 BB (6 handed) from (Format: FlopTurnRiver)

CO ($24.25)
Hero ($19.70)
SB ($17)
BB ($40.25)
UTG ($12.25)
MP ($12.60)

Preflop: Hero is Button with K, K.
1 fold, MP raises to $0.75, 1 fold, Hero raises to $1.5, 1 fold, BB raises to $3, MP folds, Hero raises to $9.5, BB raises to $40.25, Hero calls $10.20 (All-In).

He would have to be a uber nit value plus for me to fold this.

I saw the stakes and your hole cards and knew the answer....No way I am folding...If he has AA, so be it.

You beat QQ- and AK too much at 25NL to make a fold worthwhile...I need to see like a 2% pfr over 200 hands to make that laydown

Yeah please god raise to more than $1.5 you accomplish nothing with that, if he has something like a suited connector and you minraise him, he's just gonna call and probably bust you on a flop thats good for him because it didnt cost anything. I'd say in the hand in question dude has aces probably 99% of the time but I've seen so many inexplicable things happen at NL25 that I'm just not folding.
