I would fold here unless I had reason to think UTG might be the type of player who would limp with AA and/or KK in this spot.

If I thought there was a high likelihood that he would limp with AA and/or KK in this spot, then I would raise if the opponent doesn't go to showdown too often (so in particular has a good chance of folding AK UI at some point in the hand). If he is committed to showdown, then I'd probably prefer to call.

But my default play is to fold here without any reads, assuming you have a fair number of hands on UTG. Even if it is wrong, I doubt it is giving up very much.
