Bubble play - was this right?

This was on the bubble of a 5.50 45 man sng, wondering if I should have sat this one out and waited for the short stack to bust or if this should have been played as is or played differently. Advice is welcome!

4b shove pre

edit: actually, im not sure. it might just be an open shove pre.

Something about posting hand guidelines <enter link here>

cue spoon

Oh, I'd just open shove this short stack UTG.

Shove pre. the end

See: HoldemResources.net: ICM Nash Calculator

It's cutting off the last two places in the structure, but it's an obvious shove.

As already stated, easy shove pre. Do not go by or even consider the result. You got it in as a solid favorite which is all you can ask for. That the cards fell badly does not mean you should have acted differently.

Agree with the others: shove pre-flop. You're not going to fold here, so don't let others see a cheap flop or think they can raise you off your hand.
