I'm not too proud of this hand, I played it as a rookie, I might have misplayed it on every street, so I'm looking for random thoughts. Thx.

Ugh, it's really weird on the river.:)

OTF, I'd probably donk/raise if my opponent is aggressive and he seems so. Maybe it can work against him.

I'd also bet turn, it seems too passive for me. On the river I could let it go. There are some str8ts and some underflushes in his range as well I think, so I call... what is kinda weird that he was playing this hand kinda passive too. I cannot imagine he'd check back a set on the flop, so I think it's either a badly played straight or a flush that we beat.

Danger!
My comments are not necessarily relevant in HU topics yet:D

I think pre 3bet.
I think bet turn, fold on river, because enemy not go all-in with smaller flush or trips. If enemy bluffing, that is very-very-very siiick.... :)
