100nl - How do you play a missed AK vs a short stack?

[wildzer0]

This is my 2nd hand at the table, so no reads on CO. I'm never sure what to do in this situation, I pushed because it was a dry flop, there's still a decent chance I'm ahead and may get called by worse hands. Is this pretty standard, or is a check/fold better?

I'm usually the pusher. I play it the same. Makes me wonder why I don't shove pre, now that I think about it.
