“Winning Chess Openings” by Yasser Seirawan may be what you’re looking for. I like the way Seirawan has grouped the openings into classical, modern and hyper modern and explores the variations of each opening based on the development over time. It gives you a great insight into why certain approaches to the opening are now used.
John Emms also has an excellent book called “discovering chess openings” which is less focused on specific variations and more focused on the principles behind the openings.
Be very careful spending time studying the openings, however, as knowledge of the opening will really only take hold after you have many games behind you. It can be folly learning book lines when you don’t understand the principles behind each move and a good tactics book will see a much greater return on your results. Dan Heisman has an excellent tactics book “back to basics: tactics” which has a section on openings.Good luck!
Do you have any recommendations for opening literature for the entry level player, something like an overview of the most popular openings?
