The villain is unknow.

I call flop and turn because just TT and T2 of his range can gain of my hand. And a stardard player has more combos.
But OTR his bet is very large.

I have two K blockers to straight but I'm uncomfortable to call.

I've sat thinking about this from various angles and I'm just not sure. The board on the flop and turn doesn't really hit a standard UTG opening range too well; just a few hands like QQJT and random AAT2 or something like that (similar to what we actually have). Of course he could have rivered a straight, but it's a paired board.

Our range is quite narrow after calling the flop and turn. Whether villain realises this or not we don't know.

The way the hand has played out seems unusual, which adds to the possibility that it's a weird bluff, and my curiosity wants to know what he has, but I just feel like we're almost never good if we call.

Looks like a pretty easy fold on the river imo. His range is pretty polarized to AA2*, TT**, A2TJ+ here unless he is a total spaz.

KK blockers to the straight seem irrelevant but from a card removal aspect it puts more AQJ2, AQT2, AJT2 combos in his range.

Are those danglers in a standard UTG opening range?

They're not in mine, but I might be tighter than average UTG.

It sounds like improvement on every street. The removal, it does look like it gives him a mix of cards on the board. There is little reason for him to keep betting like that if he does not have at least a straight, so calling or raising with a range of straight or better should be good as that is the range one also often will have here.

You can take a look into histories to see what players have when they bet the river (if anyone ever calls). Personally, I simply called many times when I wanted to know, at PLO10, that cost me some hundreds.

APTxs is a standard minimum UTG open raise, though they can be tighter at Stars (zoom), and so, likely having read some other books where they play 4 card hands and AA, but when they open late or defend BB, in case it could be PPTxz and KK. Or in France they might raise QQ also.

AKKxs should likely 3b, but I also call with it often.

River is an easy fold.

UTG's value range otr should be TT+ (can include the random 99 he backs into). Bluffs should be some fraction of QTxx. Purely from a card removal perspective, having the two kings is actually detrimental. It's still detrimental if you widen villain's value range to 92+.

Anyway, putting that sort of talk aside, I'm comfortably folding anything worse than a boat here.

Also folding pretty straightforward

Is raising turn stupid?

Yes
