I like to limp AA from UTG when the tables got a few LAG calling machines, they will call there stack off with 8-8 and up. With a-js, a-q, all that crap. Plus it lets a bunch of money get on the table and then lets me pick it up dead, and isolate 1 or 2 weaker hands. I tend to do this more at 25$ and 50$, though.
