Hey,

Preflop, flop as well as your turn raise look good, defo a high frequency raise on the turn with all the draws. This river lead from the SB is pretty concerning, and somewhat polarizing in my opinion. 65s A5s as well as 44, 33 and KQ are definitely a concern. Most importantly though I don't think he will find a call with many worse kings here to justify the raise. He will likely have some suited K9876 and offsuit KT but even for those it is not a fun spot to be in facing this river raise. I think we can just call the river and not lose sleep over it when we do run into some worse Kx.

Cheers.

I'm just calling river, I'm having hard time to imagine seeing offsuit KT,K9,K8 there. So only worse hands which calls our shove are 4 combos of KT-K6s. Even those calls(pre) looks wide to me, and if he had those hands there (2) A5s and (2-4) 65s.
That said calling river and do you think if he blocks 55 there for no reason he will call river allin?

I would just fold preflop, KJo plays really poorly 4way againts a 5x initial open and two calls.

Turn raise is already quite marginal given that the SB is betting into 3 players and there are still two players left to act behind you who could wake up with the nuts occasionally. I would personally just call, but I'm not going to argue too much againts raising because the board is very draw-heavy.

River seems like a pretty clear call to me, SB line is supposed to be very polarizing, even though there is a subset of player profiles who can show up with a hand like K7 here. But overall I think villain has a boat or KQ a bit too often for us to raise KJ.
