I have no idea what people are talking about when telling you to fold the turn. If you're so sure you're drawing to a two-outer (where if you hit it on the turn, many people will still have redraws set up for the river) why not fold the flop?
The answer, of course, it that the fold would be ludicrous in such a large pot.
This is still the case on the turn, except you have more outs. I really think it's not reasonable to narrow down UTG's hand as much as you have, but hey, you were there and I wasn't... but all the same, I think a turn fold is bad.

That said, a turn raise is a spew, as you will fold out UTG's AAA approximately never. Just call, fill up, or better yet, hit quads, and you'll be all set.

Are we playing no-limit here or something? Are we afraid of a pot-sized bet on the river or what?
