The Vienna Gambit is pretty effective up to about 1500 level. Above that black usually knows the main lines very well and white is not really any better than black.

A generalized form of the statement is that an opening is not as effective when your opponent knows your opening better than you do. This begs the corollary - an opening's effectiveness improves with how much better you know it than your opponent does. Implied as well is that this is especially true for opening principles.
