It was our second game, first game lost in 4th hand with AA on a K83 board, he had K3 and we went all in on the flop.
Now I was convinced to call all streets but after his river bet I decided he got 2 pairs like in our first game.

Any imformation about his frequencies? SB raise/cbet/turn cbet/af? Typically folding the river is not going to be a big mistake if it is one at all, you have a pure bluffcatcher vs 90% of people and not many people barrel of like this w/ air on this board

He only reps two pair. I don't like it but I'd call with K8o on this river, especially since you have history with him seeiing you lose a tough hand previous game, he might figure you are a bit gunshy. Readless, this is tougher and I hate it but I still call I think.

This villain is not lookin so smart
It looks a 3 street maniac bluff with a busted draw. Flush, str8 not possible...crying call

If I had a better kicker I would reraise him at some point. It was close to call or fold, but I find myself in these leveling spots, when I see them raising/calling preflop with K2-K3-...K5 prior and I am afraid after that to call multiple streets with not the strongest kicker, because of the 2 pairs thing.
He was very loose and I play without HUD for 1 week due to some technical errors.
Thank for your responses guys.

Are you calling river with T8 here?

I folded K8 and to call with T8? I would fold T8 OTT vs his raise, but he was very loose so I think I am a nit.

In my opinion T8 and K8 in the exact hand are virtually the same.If villain valuebet 3 streets he has almost always beat you with K8 (very few worst kings and he probably check back river with them or bet less).If you believe that villain is that spewy that he will bluff 3 streets on such a dry board (very few draws) then you should call even with 2nd pair.Sucks when we have to fold TP but unless you establish some great read that he is crazy maniac i elect to fold here.

Thank you guys and mermigi, a very pertinent opinion.

I agree with the earlier posters about it looking more like a bluff than a value bet, the only thing I'd have to add is that V's sizing OTT especially, and maybe river too, it looks like a bluff to me. Why would he valuebet 2 pair+ with a pot sized bet on that dryish board, he would be worried about scaring away your low pairs. I'm not sure what combos of 1 pair + hitting 2nd pr on river would bet like that either, maybe a 43o that hit 2nd pair on turn and was feeling vulnerable?

In the first game he played his 2 pairs fast,here he bet very big t+r myb it's a good reasone to fold river.

against a random thats has a wide c-bet percentage i call this easily
if villain has shown to be reasonable and not too aggro i fold this.
if villain is an aggressive reg you probably wont make a huge mistake if you flip a coin to decide if you want to call or not.

why you call easily if he cbet wide?
you mean wide cbet flop?

yes because my perception of populations tendencies shows that people are either too aggro or too passive and if they open close to 100% and c-bet flop 100% they tend to be more aggressive.
Not many people will c-bet flop with 73o and then just give up on turn everytime.
They tend to throw good money after bad one.

But there is a ton of little things op should have noticed by now to make the decision easier. How does he play draws, whats his Aggressionfrequency overall,does he 3x as a standard or is this new,has he reason to be frustrated,has he reason to believe that you call down lightly,did you scope him?

It was the correct decision imo . He mightev as easily have had kj or ak in that position or smth that has you beat so i think its a good decision . in the long run though i dont think youll either make a lot of money or lose a lot of many
