OK, this is something I have been trying to determine for a while now.

Lets say it is the early stage of a micro MTT. I get KK dealt to me pre-flop in a late position (on the button). At a 10 person table there are 2 calls before me and I raise 3x the big blind. One person calls, the second person re-raises 2x my initial bet. My gut reaction is to assume that I am dealing with 2 other people with top 10 hands and that I am not going to be able to to much to push them away apart from following up with an all-in push. I push all-in, person 1 folds and person 2 calls and shows AA.

Based on the scenario above, if I get KK and somebody has AA, it instantly means I am going to be either crippled or knocked out of the tournament. Without flaming me, what am I doing wrong and what can I do to save some of my stack from this sort of devastatingly bad luck?
