I might just fold PF, Q8o is kinda trashy vs a tight player imo

I don't really like calling the c/r but if he's been very aggressively c/ring the turn often then I guess its ok. I'd check behind the river because he could easily have you beat here. I kinda feel like when he doesn't bet the river, if he was bluffing, he's giving up on his bluff seeing as stack sizes here make a river c/r kinda dumb, he could just shove it all in himself as a bluff.

I don't really like turning our hand into a bluff here because we have decent SD value and it just feels like its an unnecessary risk when I think your hand is good here a decent % of the time
