Fold or Shove? FTP 32K

Here is the hand history. Given I didnt raise pf, now shove or fold? UTG (DonkeyOut) was tight, tricky player. Thought DonkeyOut was much stronger. My username: haitian. Any replies appreciated.

Also, I was obv calling bb shove if folded around, but was disinterested in 3way pot. Didnt see much fold equity in 1hole. Biggest mistake was passivity PF. Again, thanks for advice.

And some more food for thought. Deeper same tournament. Probably should have further defined my hand on flop.

Pretty much bubbled. Blinds 500/1K. Loose aggressive button open shoves for 15K. I have ~12K with wired fives. I call. He rolls a4o. Three outter on the river.
