Tan - 1.e4! - The Chess Bible - Volume 1. Livre en anglais sur l'ouverture 1.e4 au jeu d'échecs. “I believe that Black has a wider margin of error in the closed games than in the open games. Even if they do not know all the details of a certain line in the former case, they will end up with only a slight disadvantage in the majority of cases. The same cannot be said about the defenses to 1.e4. In this book you will find that Black must tread carefully if they play an offbeat system, as I have discovered several refutations to the most popular and widely accepted lines within them.”
