With those circumstances (stack and blind levels), all in.
At that point, it isn't like you can afford to put in a 600 BB call but then "fold" to a reraise, so I'd much rather push it up front with the chance that I will at least get the blinds in a walk (which itself is almost a double-up). If I get called, at least I have K/J, which is likely live with an over to a player who would be inclined to call with a weak ace.

If there is a dominating ace or PP behind me, that's poker. But 4 handed, those blinds, a stack that size with a folder ahead of me, K/J is all in- and more times than not will be good.

As another poster said... You only have one hand before the blinds decide your fate- I'd much rather go with K/J than (r)/(r) when I catch the BB.
