Chess Explained books provide an understanding of an opening and the middlegames to which it leads, enabling you to find the right moves and plans in your own games. It is as if you were sitting at the board with a chess coach answering your questions about the plans for both sides, the ideas behind particular moves, and what specific knowledge you need to have.
The French Defence is one of the most important chess openings. Its qualities are such that it appeals to a wide range of chess temperaments: it is solid yet uncompromising, and with a variety of chaotic variations to appeal to the most bloodthirsty of players, but also offering more tranquil lines to those seeking a quieter existence. While it is hard for White to avoid at least some imbalance in the position, he also has a wide choice. In some of the most critical lines, he accepts major structural weaknesses in return for piece-play and dynamic chances, while he can also seek to establish a modest space advantage without such heavy positional commitments.
