PP 15/30: KK River Decision

[Levi King]

This is another "back to basics" question - few hands on the opponent, but the numbers read vpip 30%/ pfr 2% / 40 hands:

This is easy, I have to call here, right? Who hates the 3B on the turn?

Yeesh,
Tough call on the turn since a pair likely cr's you on the flop and since SB is cr'ing two players on the turn - that usually signifies strength.

Yet I can't fold Kings to one measely check raise with the board -- and I want to lose MP2 - so I prefer the 3 bet. I would usually shake my head and fold to the 4 bet though. It's definitely odd for MP to call 1 bet then 4 bet. Why wouldn't he/she have raised the turn the first time? -- probably a flopped set that didn't want to lose the UTG player. But just too likely you're drawing dead or to 2 outs. The parlay of two cr'ers being on flush draws or underpairs is too unlikely.

If I had called the 4 bet - then, shazam you're faced with a horrible river card. As weak as it is I probably check fold the river. I just think you're good there 1-2% of the time. If it's early in a long session I might call down-- because folding the river for one bet in a big pot just LOOKS weak and I don't want my opponents taking shots. But generally, unless I know MP2 is very LA I fold.

I think the 3B on the turn is imperative for the reason you state, but the cap is problematic. Still, I have to call that, right?

When the A of diamond hits on the river, I don't know what to think. When I call the cap on the turn I can only hope he's on a draw or mis-guided top pair, but the Ad completes the flush and gives an overcard. It seems like I should be able to find a fold here, but I can say with confidence that I have never found a fold in this situation. Is this a leak, or do you guys agree that a call is in order regardless?
