Kc 9c, I think the best line in this hand is to raise the flop or x / r in turn ..
which in turn would try that had the most chips in the pot .
I would, therefore I making x / c flop x / r in turn , as x / r flop and turn.
to see if some pro is passed and to see how it says ..

You have to be betting the river there. You just lose way too much value by not betting. I think defending pre-flop is a mistake as well. Don't mind the flop and turn play.

Villans line doesn't make sense to me. Would he be limping with AJ or a pocket pair pre-flop and then put a pussy bet out there into multiple opponents with a set or a gut shot on the flop? Like a weak pair-type hand that picked up an open ended draw on the turn is the only thing I can think of that would play the hand this way, something like J-10. Like the only reason for him to play a set like that on the flop would be if he's trying to induce and I just think you can't be scared here.

Also like a check raise on the turn. Depends on game play and how you think you can extract the most value from villan.

I would never x/r dat turn, just a total overplay given all ppl c/behind Qx here.Leads the turn make more sense to me.
I don't think that leading the river make sense too, maybe we can get AA to call , that the only hands, that can bet turn and checkbehind river i think.

No really, vs decent player, you never have the best hands river, the guy, have full house or straight pretty much always, the question is can he overplay some hands, can he bluffes this spot, and hard to answer at this question especially in a live game;

If you assign the guy a 28% opening range, your three of a kind is good on the river 77% of the time. If you're not betting three of a kind on the river for value, what are you betting? The flush draw didn't get there (I know you have blockers) and he'd have to be betting into three opponents with nothing but a gut shot if he had a straight.That'd be a pretty big leak if he's doing that. If he has a boat wouldn't his sizing on the flop or the turn be larger than 60% of the pot?

The only thing that makes me second guess this is that people rarely bluff the river in live play. Then again, Hero limped out of the blind and checked on every street. Why wouldn't he think hero is weak and bluff at it.

I still don't know how you're defending with a weak King and three opponents acting after you. There have to be better spots to pick than that.

Idk, maybe I'm just married to trips- What did your analysis look like for the river call - what range/combos did you assign him?
