big draw on paired board

[scooby]

After taking a break for a bit from poker to start a new job, I got invited to a home game. It's 25/50 limit, playing 7 handed with people from the financial world.

UTG (very rich, straightforward) raises, which means that he has any pair or two broadway cards. UTG+1 (loose and straightforward) coldcalls, which means that he has two cards. CO (decent player) coldcalls, which he probably won't do with offsuit dominated hands. I 3bet from the button with K [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/diamond.gif[/img] blinds fold, everyone else calls.

Flop comes down an interesting A [img]/images/graemlins/diamond.gif[/img] A [img]/images/graemlins/spade.gif[/img] T [img]/images/graemlins/diamond.gif[/img]
UTG bets, UTG1 calls, decent player folds, I raise, UTG looks at me for a second or two and calls, UTG1 calls.

Turn is K [img]/images/graemlins/club.gif[/img] UTG thinks and checks, UTG1 checks, I check. Thoughts so far?

I need to evaluate the river. I don't want to get checkraised with somewhere between 0-12 outs, I'm probably never folding an ace, but I'm not sure if I can get a call out of UTG with a hand like QQ or JJ. Also, I'm having a tough time putting UTG1 on a hand.
