Ace-high flush on a paired board

I felt I played this hand pretty meh on all streets, I feel like my hand is pretty transparent by how I played it. Or is this fine? How about raising the flop? I just sat down, I only had some datamined stats on him and he
s around 40/20. Other opp is pretty loose too, so I guess thats why I didnt raise the flop because I thought that a semibluff didnt have enough FE against two loose villians.

Maybe just push turn?

I wouldn't raise flop. I think its fine unless you know them well enough to find a fold on turn or river.

i play it the same. CO's line doesn't make much sense.

if he has the flush, checking here is brutal because it gives people with Qc or Ac to draw free.

if he has a J, CR here is dumb because the flush is out.

so that leaves a boat. but even then, i think a boat would make more money by betting out rather than check-raising. letting a Qc or Ac get a free shot to draw out would be terrible.

given the action, i think you played it fine.
