This is a brand new series which provides an ideal platform to study chess openings. By continually challenging the reader to answer probing questions throughout the book, Move by Move greatly encourages the learning and practising of vital skills just as much as the traditional assimilation of opening knowledge. Carefully selected questions and answers are designed to keep you actively involved, and allow you to monitor your progress as you learn. This is an excellent way to study any chess opening and at the same time improve your general opening skills and knowledge. In this book, Grandmaster John Emms invites you to join him in a study of the Nimzo-Indian - an opening which is highly popular at all levels of chess and has been his favourite defence to 1 d4 for over 30 years. Here he shares his experience and knowledge, examines the opening from both sides of the board and offers answers to all the key questions.
