KK early to middle in the game, what to do?

[Fatdogs12]

I had a problem with KK early in 2 games in a row. In the first game I had KK with 7 people left. I bet 150 preflop with blinds at 25/50. someone raises it, the next person pushes all in. I call. It was AQsuited vs my KK, they hit an ace and busted me.

Do you think I should have just waiting till it was later in the game? I don't know if I could have gotten away from KK.

The next game on the very first hand. I get KK I raise to 75 with the blinds at 10/15. I get a caller, on the flop we get all out money in, they have AA to knock me out.

This has been real -EV for me so I am wondering if I should really just in general chuck most hands early in tourneys... I mean an extra 800 chips is good but it isn't really worth losing a shot at placing in the money.

What do you guys think?
