My own thoughts: Flatting the preflop 3bet was weak, I should have 4bet him preflop. I wasn't thinking enough and made another preflop mistake that snowballed. I don't absolutely hate just flatting here, since even though I'm OOP it disguises my hand and could lead him to make a big mistake on a K or A high flop with AXs/AQ/AJ/KQ/KJ.

The strength of my hand kind of makes up for flatting OOP, but I still think it was a mistake overall and one I've already told myself I wouldn't make again, so this should serve as a lesson.

I'd already expected to C/R the flop before I ever saw it, when he just flats the C/R I believe he's either chopping, somewhat behind (AQ), or drawing to the flush or straight. More likely the flush, since although he's a bit spewy I don't think he'd flat here with a gutshot.

AJ would reraise all-in, and KJ too. JQ may flat, but that's all I can think of here that's ahead that flats apart from sets. I think he'd fold TT-

When he flats the turn, he's either drawing to the flush without odds, or thinks he's chopping with AK. He'd have shoved a set here I reckon.

To little left behind on the river to fold to an aggressive player like this, who is certainly capable of trying to push me off a chop.

Do you expect to be chopping here?

At first I really hated my play in this hand, but reviewing it later, although preflop was a mistake, I don't actually think postflop is that bad. Knowing his holdings helps make that determination, but I'm interested in alternative opinions without the benefit of knowing his hand.
you picked a very poor line that doesn't make any sense based on an awful assessment of hand ranges.
