4-handed KK play

[riffraff]

$.50/$1 Paradise

UTG limps, MP Raises, I'm next to act and 3-bet with K[img]/forums/images/icons/diamond.gif[/img] K[img]/forums/images/icons/heart.gif[/img]. everyone folds to BB who calls 2 bets more as does UTG. MP caps it, everyone calls.

I've played with MP before and he seems pretty reasonable although straightfoward and my first read on him is AA or (much less likely) KK or QQ.

BB bets out, UTG calls, MP raises. I 3-bet it, again both BB and UTG call, MP1 caps it, everyone calls.

BB and UTG check, MP pauses a second then bets. What's your play? I am willing to put in one more bet considering the pot has grown pretty big, but will fold if there is any more action by the BB or UTG. They both call however and we see the river.

BB and UTG check, MP checks, I check. (Does anyone bet this river 4-handed?)
