KK vs. AA

I wound up running my KK into AA twice in 500 hands last night. The outcome doesn't really matter (though both times I flopped a set and once I hit quads), but the question is: Is getting KK all in pre-flop an EV- move? In other words, should I be avoiding committing my stack with KK pre-flop? Also, is KK AIPF vs AA simply bad luck, or is it bad play?

I suppose I'm going to run into all sorts of situations now that I'm playing down a level at $10NL on PokerStars (I started with that $50 trade from my friend; Tilt for Stars). All I can "afford" on there is .05/.1, so I see a lot of *TERRIBLE* play including checking AA down against a two-tone flop, checking sets down in similar situations, flopped nuts checking the river, etc. It's comical! However, the $10NL game is *VERY* easy! VERY EV++++! The players at this level play any suits and any gappers. Most cbets after pre-flop raised pots (probably 75% of the time) take down the pot. It's EASY!

I want to get to SilverStar status, but I think that is likely impossible at $10NL given that I played ~800 hands and accounted for 31 VPPs (1200 to get to Silver). I suppose once I make SilverStar, my accumulation rate for points will be much faster, but if I get 31 points / day, I'll need 38 days in a month :-(. P.S. SilverStar enables me to trade points for cash, similar to rakeback.

Hopefully, I'll build up to $500 quickly so I can move to $25NL. If tonight is any indication, then I should be there in about a month.
