Ravel didn't outsmart Rias. It's just that everyone happens to fight who they wanted. However Rias did get the best of Ravel with her surprise attack which caught Ravel offguard. Ravel is a good strategist but her weakness is she can't predict her enemy's moves and they tend to caught her off guard.
