Limping AA UTG - 10 handed full ring?

[mustmuck]

You're dealt AA UTG in a full ring cash game. You have GameTime+, or whatever, open and you're looking at the average PFR for the table.

1) Do you EVER limp AA under the gun?

2) If yes, what sort of average PFR for the table would you limp here with, assuming that the main aggressors aren't the SB and BB? That's a player average, not the percentage of raised flops (this might be an interesting figure though). I think this is a tough one because we have two of the aces, meaning that AK, AQ is less likely.

I have a hand somewhere to go with this where I tried limping aces UTG with a table average of >6%. Had about four callers and then the BB bumped it ... which brings me to question 3!

3) So somebody raises and it comes back round to you. What now? A reraise here would seem to scream aces. In fact, this alone could be a reason not to limp in the first place.

I assume people try this with hands that aren't aces as well as aces. This would seem to be the LAG way of doing things, but I don't play LAG so well.
