5th step bubble---thoughts on my play of this hand

[tomscuba]

Bought into first level and worked up to level 5. 6 left, big stack is 2200, I´m small stacked at 940, blinds are 300-150. I find K-9 UTG and go all in.
I feel good about the play--tho I was called by pocket 8´s and got no help. My thinking is in that situation I need to attack, in 1 hand my raises won´t be effective, and the chances I can steal are increased as the bubble is upon everyone. I´m also relying on the gap concept.

Thoughts on the play?

I´m a half glass of whisky later, so sorry if the post sounds--uuuh---drunk.

Cheers,
