I'm quite the noob so excuse my ignorance but ill give this a try and please correct me if im wrong"

First I hate playing big hands in unraised pots (cuz a min raise is not a raise in my book) but as how the hand was played you have to put him on a set if hes a decent player and would make your flush 35% of the time.

Now if he slowplayed an overpair (wich i tink is doubtfull) you make your hand by the river 51.2% of the time having what I believe is 14 outs (9 diamonds, 2 jacks, 3 tens).

And If hes on tptk (wich would be a really bad push on his part) you still have 12 outs for 45%.

Thus said, I am perplexed on the action to take; I'll let the more experienced folks here guide me trough.

this should be the easiest call you'll ever have to make.

To answer your initial question, after raising to 10$ I'd never ever fold in this spot, so yes I'd get it all in as played.

I don't like the UTG open-limp. This hand plays easier if you raise.

I have been playing with mixing in 3xBB raises. So maybe throw out a smaller pre-flop raise. Switching back and forth from 3-4 seems to keep people on edge.

I like raising it UTG too. I'd rather fold than limp.
