I believe the pro side of a pocket would be the inside.
This is the correct answer. Pros don't aim for the best miss.
Cheating the pocket causes everybody, pro and amateur, to miss more often. "Cheating on the pro side" means you're trying to miss the shot more often so you won't leave as good a shot for your opponent. The only sure way to not leave your opponent a shot is to make your shot.
