If you're tired of playing the Petroff, there's the Viennese game... but not just any Viennese game, the modern one, i.e., the 3.Fc4 variation, usually followed (if Black is willing to cooperate) by 4.d3 and 5.f4. Not really modern, in fact... Now, this is from the Chess Stars collection, so it's well done, dense and very "high level", so if you're into the subject, this book is for you.
