KQo on button, should I have pushed?

[Meatmaw]

Wasn't sure if my stack was desperate enough or the hand good enough to push, but I'm thinking it was. Should I have?

Push. They have big stacks, so when you bet like that, and they look down at 22 or even crap like 10J suited, they may think *hey, Ill see a flop*. Just push and take down the blinds right there.
