140bbs deep readless.
-I'm SB with KK. I raise to 2,5bbs. Villain call.

-TURN 10bbs: 8942csdd. Villain check and I bet 5bbs. Villain raise to 17,5bbs. I call.
-RIVER 45bbs: 8942Acsdds. Villain bet 21bbs.

What do you do? I called and villain showed 82s. I was thinking the ace didn't really change much after his turn XR and I'm quite high up in my range. All of villains bluffs OTT missed (except 35s should he ever show up with that). Perhaps my call's just too loose?
