Flop/turn/river - I think I screwed up big time?

Villain (bb) is unknown other than the fact that he bought in for 100, posted 2 utg previous hand), UTG is loose passive…

I intended to check the turn unless I picked up a pair or diamond draw to go along with my hand… Thoughts on this hand?

why did you 3bet the flop?

Turn donks are too common to employ the free card play, imo. Also, bb has to be pretty good or LAGish to check raise an underpair. I'd call the flop and if my Ten hit, I'd probably raise and expect to loose a free SD, UI.

I think you should fold this turn.

I felt that my king overcard might be good if paired + gut shot + small chance a ten might be good if paired + initiative for a free card on turn + backdoor flush draw

I realize that may not be a strong enough case... but that's why.
