Tough one!

I might raise the flop to find out where I am at, but if called or raised, ouch, even tougher place. I think I make the fold, then kick myself for not having a better read.

I agree it is smart to give an unknown and a "semi-good" player credit. An UTG raise is strong more times than not from someone new to the table, and a "semi-good" player flat calling out of position needs some respect too. The way it played out it could very well have been AA vs KK and not two middle pairs.
