[Closed] 8 high flush vs c/r

I like it.

It's very hard for him to call a 3bet with Ax on the flop, but he could very well be checkraising it for value.

On the turn i think i'd call, too.
100BB deep i'm more inclined to ship it in, but with these stacksizes you have left almost two times the pot and i think he folds Ax too often to make it a profitable raise.
Furthermore as you said there are 3 better flushes in his range vs which you valuetown yourself while there are two worse flushes at max - 76 and 65, but he folds these preflop sometimes.

At the river i think i'd bet.
The better flushes in his range are QJ, KJ, KQ - and that's it.
So you can get value vs 2 possibloe worse flushes and tons of Ax hands which c/c the river to catch your busted FDs.
You could make it like $59 or shove, in the end it's a leveling war although i think vs his range a shove is a bit better because you maximize your value vs Ax - he would've bet a full house most likely himself because you have a lot more flushcombos in your range than he has in his.

Btw. was the BB a very bad player? Otherwise i'd consider folding preflop, 82s is too weak because it never hits and has terrible playability even if it does hit a pair (but even with 2pair you always have bottom2).
