This does seem like as good a chance as any, and if he's really been raising 3 out of every 4 hands, there's a very good chance you're ahead. Also, doing it now, if you survive and double up you actually have chips to work with and perhaps enough of a stack to scare the chipleader away from beating on you quite so hard, whereas in another round you'll have so little that even if you double up he'll just keep beating on you.

You're the shortest stack, and you're at the worst seat at the table (right after the chipleader). Better to take your shot sooner than later, and better with this hand, which actually has some showdown value, than with whatever you happen to have when you get blinded down so far that a push is mandatory.
