KK, can I fold on the river?

Can I fold this river? During the hand I was thinking any ten beats me, and QQ and JJ both got there. I hadn't been at the table more than 2 orbits, but villian seemed quite reasonable, I hadn't seen him get out of line yet. I also don't really like how I played the rest of the hand, but the river is the street I'm questioning the most.

Logically, your thinking is sound. Any cap hand beats you. However, he's an unknown. You need to see a showdown in a pot this big against an unknown. Don't sweat the call.

I would call, i think you will see an 77,88 or 99 just enough to make calling ok.

Pot is pretty big. I make a sad face on the river and call, hoping to see a badly played AQ, AJ, 99.

Also, its not likely that this guy is bluffing (who bluff caps?!), but I have seen it happen on paired boards.

You can't fold this without a better read. He could easily be over playing QJ or AQ, or even KK here. 13.5:1 is alot.
