2-5-10 plo5 line check

Straight forward as in faced up? I guess folding preflop isn't that bad?

Flop bet is too big for value? Maybe something like 75-100?
River probably a fold? You beat a bluff or overpairs who's monkey betting.
I guess we could also try and jam to rep quads? But if villain has 97/95 he's never folding. Even with a 9 he might be suspicious?
Calling seems to be the worse of all options on the river?

Not sure calling the river is that bad. You have trips and are getting 4.2-1.

I have a flush by the river

Yeah, I would flick in the call. You only have to be good 20% of the time. Don't want to try to bluff someone off a boat.

Fold for $10

Don’t think this is an open pre.

On river it’s basically always AAdd vs mediocre regs, I think a big raise or fold are the only plays. Calling is lighting money on fire.

I might bet turn small for protection and sometimes thin value.

Yes, raise or fold. I like the raise. He showed lot of weakness and the board is your range.
