Villain is maniacally aggressive. He's playing 85% of his hands from both the button and the big blind. He's 3betting 27%. He's defending his 80% button open range vs my 3bet 57% of the time. It's 3am PST when I'm playing him so it's a late night session against a very profitable villain.

I've seen him do weird plays. Like on a 763s flop he check raised 87o and then min check raised got it in on an overcard turn pretty deep (showing that he doesn't quite value his hands correctly). Not sure what to make of that play but it seemed fishy to me. Also, one other important hand to note is that in another spot where the river brought in 4 flush he checked down 2nd pair (a hand with showdown value) in position.

I guess I could have even made it $11 or $12 to go when I am 193 bigs deep...

Standard bet. Not sure what else to do.

Should have sized this slightly bigger as my sizing here leaves a slight overbet on the river. This is the type of villain on most good rivers I'm jamming river for value and getting called by a lot worse. Jx, weaker Ax, maybe even 7x with a heart 88/99. TPTK is a monster in this spot vs this loose of a villain.

Bad river card for my specific hand. I check and villain shoves the rest in. What do you guys think about this spot? I know villain is crazy and maniacal, but I think that it's hard for me to find a call here. The timing on my river check was tank about 3 seconds then check.

How should I play my entire 3bet range that bets flop and bets the turn on this river? Is villain turning worse hands into bluffs here/ am I making a mistake by folding here?

Thanks!
