In his first book (we anticipate many more), the young Hungarian author makes a worthy attempt to walk his readers through a complete 1.d4 opening repertoire. Yet while he is taking you thru the opening he never forgets the other phases of the game. As a result, the subsequent middlegame and endgame elements are remarkably well organized benefiting both beginner and advanced players to acquire powerful skills with 1.d4! In what way is this book special? How can it make someone a better player? These are perfectly legitimate questions and whenever I buy a new chess book, I essentially ask the same ones. The short answer is that this book will give you a comprehensive understanding of the chosen openings. Unlike many other books with a similar profile, it goes beyond pure theory and in addition to giving a great deal of practical advice, it touches on issues such as sample games, typical tactical strikes and, in the last chapter, endgames.   On top of all this, a homework section enables you to immerse yourself in a given topic and achieve an in-depth understanding of it in your own time. We follow this structure because as a coach, I know how important it is to receive as much guidance as possible on a new opening. Only this can lead to true mastery. Let me recommend this book to any player who wants to learn more about closed openings, adopt a new approach to chess and build up a thorough and sophisticated repertoire.  I have tested these openings with my students with good results, so I believe this book is suitable for anyone with an Elo rating from 1600-2500.
