Turn looks kind of thin, I'd still be but I'd be making it smaller to target draws and weak Qx hands, I mean they could very well have AQ here. River is just a x-f, backdoor flush hits and AT and T9 also now beat us. Really hard to see what value hand we beat on the river and their stats 56/12 look passive making me think they aren't bluffing too much here.

Pre: Standard.

Flop: I'm not a huge fan of the massive sizing here but it is definitely a bet.

Turn: I like betting again here for sure, I would be going closer to half pot though. We don't have a hand we want to play for stacks so bloating the pot as much as we have with our sizing is going to be a mistake IMO.

River: Kind of sucky spot. Given villains fishy/passive looking preflop stats I would likely be folding here (provided that is over a reasonable sample)

bet smaller on flop, bet smaller on turn and bet small river and fold to jam. as played fold river

Against a whale I don't mind the big flop bet or turn barrel.

River is still a check fold at these stakes though. You can possibly bet really small for thin value but with so many draws coming in I would play it safe.
