Live 1/3 NL hand, tough KK

[Percula]

Live 1-3 NL at the Wynn, I have the table covered by a couple of hundred. Villian is a seasoned player and has about $300 less than myself. I have not been on the table long, no real super reads for anyone.

PF, I am UTG+1 with black KK, UTG limps, I raise to $15, Villian UTG+2 calls, button calls, UTG calls.

Flop: 7[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/heart.gif[/img]8[img]/images/graemlins/spade.gif[/img]... UTG checks, I lead for $45, UTG+2 calls, all the rest fold.

Turn: 9[img]/images/graemlins/club.gif[/img]... I lead for $120, UTG+2 calls.

River: 10[img]/images/graemlins/club.gif[/img]... I check, UTG+2 pushes AI

At this point I could put UTG+2 on a wide range of hands, from a str8 draw that hit or missed to over pairs or connected cards.

Call or fold?
