AA or KK very early in a multi

[Penguinfan]

Do you go all-in pre-flop or slow play them. I almost always push all-in especially if it was raised before me simply because there are a ton of bad players in these games and someone is gonna call you, now I know AA is not invinceable, but I'll take my chances. I was called by 4 people on the second hand of a tourney once with AA and it held up, believe it or not after checking the lobby board I was still not the leader

Thoughts?
