Another rule which leads to similar results is to go all-in if a normal bet would be 40% of your stack. If your raise pre-flop and get called, you'll most likely want to continue with a bet regardless, so with 10XBB this leads to being pot-committed by the flop anyway, so might as well get it in first so you have the fold equity.

This post is an interesting situation because AK dominates many hands that would go over the top of it, so the normal raise is a bit of a baiting tactic.
