With your stack size, it's truly shove or fold.
UTG, I certainly don't mind shoving here, we're likely to get called by the shortstack, and when we make a full house on the river, we realize we were most likely good with just a pair of 8s. More times than not, you'll get a big ace to call you and coinflip to put you at over 20 BBs, out of the tournament, or pick up your blinds.
Raising to 3 BBs puts the pot at 6.5-7.5 BBs if you get one call, your stack at 7, and gives anybody who suspects they're live a reason to call.
Limping in gives a cheap price to everybody who wants to see a flop, and any flop action on a board that doesn't improve you is most likely going to induce a fold.
Folding preflop isn't terrible, but you're likely to be ahead, at worst a coin flip, should you even get called. It depends on the players at your table, but I definitely wouldn't be folding here with only 10 BBs and the blinds right at my door.
I'd jam pre, as I'm sure many would. If you lose, you lose.
