Villian is playing 38/18 with 10% threebet, 44% fold to cbet, low AF (1,6) and super high Went to showdown (48) (samplesize just 160 Hands)

BB was also a fish and the button wasn't to active, so i think my preflop open is standard. I don't see a lot of merits in betting this flop versus this villian.

Turn is nice and I decided to raise to get value from draws or to induce light calldowns from weak madehands.

When he raises it get difficult. I don't often checkbehind the flop and raise the turn, and have no Idea how likely it is that an villian is going crazy against this line, but in general I don't see an opponent like this go crazy with a draw or a 2 pair hand. Even small sets often just call a raise this deep. Is it to weak to just call the turn? It's put me in a kind of negative freeroll situation, versus topset i lose everything everytime but he could give up combodraws or undersets on the river if i call. I might get more value from bluffs if i just call or save money versus topset if a draw hits on the river.

Villian instapot the river, he is repping ultrathin, since I don't give him credit for to many 2 pair combos on the turn. But he could play 55/66 this way, or just go randomly crazy, so I guess I have to call...

he was just going for a flop c/r with KK. he cant have KJ, maybe he has 66 55 but with that he b/calls turn i guess.

pretty fked up spot imo

i either jam ott or raise fold really depending on the feel how villain plays.

r/f turn seems really bad from a theory perspective but probably the right play here. Sucky spots all around.

omfg...
pretty fked up.
As played I think I'd call river. But in the other hand all his moves look like someone who is trying desperately to get value from something, since he wanted probably to C/R flop.

KK

as @bartolomeus said: I think if he had 55 66 he'd just call turn.

In the end, hero... ?

Call river and smash up the nearest thing to you when he turns over K6. Probably just jamming turn though. He probably 3-bets a lot of KK hands so don't think KK is that big a part of his range and we can't just go raise/folding sets OTT. Sucks that we have no redraw bar quads if he does have the KK but what can ya do! Either way I think shoving is better than just calling so we don't make any mistakes OTR. Only calling if villain is likely to just spaz out and might be really wide OTT.
