I think there is a little bit of a problem with the assumptions of this play.

To make this play you SIMULTANEOUSLY have to assume:

-The button is GOOD enough to lay down just about anything to your all in
-The button is BAD enough not to realize he is donating 400 chips to you should you decide to push all-in and adjust his raising standards accordingly.

I think you either have to decide you have a good or bad opponent, but it is a bad idea to assume you have both.
