Flop bet could be arguable but I wanted to fold everything except K, or high pair. got one caller.
I believe turn is mendatory bet since I got a wrap (fold to a raise)
Otr, i hit my straight and he checked. Should I bet to get more value from Kx? If so, how much is normal?

A little less than halfpot, he could have quads tho..

Bet riv, flop and turn are debatable, though reads would be helpful

I thought turn was a mandatory bet unless the villain is a calling station. hm... flop might depends on vpip but i donno

flop and turn are good IMO. OTR I usually check back, but betting is probably better: he should have more trips with good kicker in his range than boats, and he should rarely be bluff-raising. So b/f around half pot OTR.

If villain is a maniac or if you think you're going to get bluff-raised OTR somewhat often, then checking back is better.

I disagree with this. My first toughts were "nice we hit a wrap -> eezy barrel" but after thinking about it checking back is propably best. The turn doesn't change the board much of at all, and I think he is gonna continue pretty much with all of his flop calling range (hands like QQ and JJ are the only ones that I think are gonna fold). If you think about it makes no sense for him to call with a range that is folding the turn often. We also have a tough decision of wether to keep on bluffing or not if the river blancs (giving up on the river would make the turn bet even worse imo). So even though we pick up some equity I think that betting the turn here is -EV.

On the river as played I'd go for a valuebet around half the pot like people have suggested, he has enough trips in his range that betting is propably profitable (and he won't be turning a K into a bluff almost ever).

unless villain is a super maniac and you can bet/call.
