KK - scary opponents scary board, what's the right play?

[Bob T.]

Ok, right off the bat, I'm open to discussion on any parts of this hand, but what the best play on the turn is, is what I really am interested in.

UTG, ( 6/3 for 60 hands open raises), the next player a loose (50% vpip) coldcalls, because that is what he does. I have K [img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/diamond.gif[/img], and threebet. So far, So good, I don't think that UTG's range is so tight, that I can't play KK here, and even if it was, the coldcaller probably gives me an overlay.

But, next player (16/0 over 60 hands) caps it. OK, what do you think his fourbetting range is? Yeah, me too, the only question is, what color are they.

Everyone else finds a fold, and the four of us see the flop. ( 8.5 Big bets)

Flop K [img]/images/graemlins/heart.gif[/img]8 [img]/images/graemlins/heart.gif[/img]5 [img]/images/graemlins/heart.gif[/img]. Good news, bad news.

Three checks, and the capper bets, UTG, and the loose guy fold, and I checkraise. Here is my first question, he doesn't have a flush yet, should I just smooth call here, and let him keep betting, and hope for a checkraise later on if no more hearts appear, or is it better to get my raise in here, and take control of the betting, I really don't want to be giving free cards on the turn, and if there is no improvement, if I don't lead out, the river is going to get checked through.

Ok, now my opponent either has the flush, and I am drawing to ten outs, or he doesn't, and he has one out for the win, and a 9 hearts for a chop.

What's the play here? Bet/call -check/fold the river. Or Check/call, check/call?
