Villain is 36/20 fish. Folds to c-bets 56%. And only goes to showdown 27%, so he's on the less crazy side.

I have $30 left. And it seems impossible that my hand is good. But I'm getting such good odds. I really wanted to just fold and save $30.

Also, should I have sized things differently after the turn paired to leave myself room to fold? He was bad so I was kinda auto-piloting going for max value.

id call here. if hes a fish he can deffo have worse hands here, im sure were getting odds here to call all day everday

I think against a fish, no you can't fold, as he could have A6 or another 89 hand (and possibly very rarely something else I can't think of).

i'd just size my bets bigger and overbet jam river vs a fish.
as played i'd still call as i expect the fish to have 6x some of the time at least. i also expect the fish to raise sets/two pairs on this flop, so i'm not all that upset calling here.

Seems to be a clear call for $30. You need to be good less than 20% of the time, and although I can't stove anything right now, just by counting card combos you're well above that figure against a range of TT, 77, 66, 76, 98, and A6s.

Man I always hate when this happens, but I think it's still a call even though we're not good very often.

Board: 7h Td 6d 6c 2h

Hand 0: 20.455% { 9h8h }
Hand 1: 79.545% { TT, 77-66, 98s, 76s, 98o, 76o }

And that's assuming he's always slow-playing everything, never bluffing, and/or shoving worse for value. Not the worst assumptions against this type of player, but they will show up w/ some rando 6x or whatever at least some % of the time.

just pot pot jam vs fish imo

Yeah, this too.

Yeah I really need to experiment more w/ different bet sizing against fish. Lately I've been over-betting flops like this and it seems to work reasonably well. Fish seem to care more about the absolute $ amount vs what % of the pot it is.

Ye not going to fold. I also agree that shoving river is +ev vs this player. He isn't folding overpairs let alone trips

Like other people have said, pot pot shove. As played can't fold.
