If you're playing too tight early in tournaments, start playing more hands with high implied odds-- small pairs and suited connectors-- and start taking more flops (and picking up pots) in position.

KQ is not a high implied odds hand, but I often play it for a limp up front anyway; you can take a lot of chips from KJ, KT, and QJ, all of which you often see in early stages.
But I still play it with a deft touch. I wouldn't commit too much of my stack without at least top two pair.

It's hard to articulate. You have to feel comfortable that you can play it profitably before it will work out for you. Of course, the best way to learn to do so is to start playing it, but you can lose money in the meantime learning.
