When do you raise w/ AQ and when do you call a raise w/ AQ?

I usually limp w/ AQ in EP/MP and will raise with it in LP. Additionally, I will usually fold AQ to a standard raise in most positions unless I KNOW the player is loose. I might be a little bit tight, but I don't feel like getting up against AK.

I won't raise in EP with A-Q, I've been experimenting with limping with it though. It just seems bad to limp with something in EP when you won't call a raise with it. Lots of pots get raised so it seems like more often than not you'll get raised off your hand. I generally fold in in EP. MP and LP I'll open raise every time. I'll limp with it in the blinds.
