I'm with 'rilla, limp it and hope for a set ... you don't want to be pushed out by a bigger pp preflop. I've run into some players that try to trap pre-flop ... they won't raise QQ or better unless someone else raises then they come over the top big. Against these players I like the pre-flop info raise with hands that are easily dominated by big pocket pairs when they do hit the flop ... AK-AT, KQ, KJ. Some of these guys are set off with just a minraise too.

You don't mind seeing a flop with TT against AA. Seeing a flop with AQ against AA sucks. It's much easier to know when you are ahead with the med/low pocket pairs.
