I would fold preflop versus utg and I'm oop, particularly as you say, utg is competent.
Getting to the flop I think this is a ck/c at best and fold turn unimproved.
Once I raise and get 3bet I'd drop this quicker than a hot rock.

It seems to me you suffered from ramping the heat when it wasn't needed. I think it's called 'forced agression' and is very costly. It's a bit like tilt but us down here at micros don't always recognise it as such.

I would suggest you get hold of something like equilab or flopzilla and drill those equities.
Just the fact that villain pots the flop usually means they aren't folding any time soon to.

@Pwll thanks for your reply.

I went through this hand in flopzilla.

During this hand I thought that this was way closer. Flopzilla told me otherwise. The only thing that is open for me is the question if villain is ever bluffing in this spot. As I said i do not think so, so the 28% versus the needed 38% stand and this is a fold.

I am trying to publicly go through my hands and give my thoughtprocess in advance.

The fact that you played this hand against a competent opponent raising from UTG is crucial in my opinion. This might be a fine call and solid flop raise against your average button opponent who's going to play into you with a very wide range, but if you consider how narrow average UTG preflop open range is, to begin with, you'll quickly realize that the EV of your bluff flop raise is not very good. This is doubly true on a lockdown board like 6J6 where villain might elect to pot control his showdown value hands (Ax and pocket pairs).

Long story short, if there's one thing you should learn from this hand it's that you should respect UTG/MP open ranges more. You're not doing yourself any favors by calling a speculative hand out of position against a range full of Ax type hands, strong broadways and pocket pairs.
