ChessBase has revolutionized chess! The ChessBase database has become the international standard for top players and amateurs alike. Over time the software has become more extensive and therefore more complex, so that not all of its many functions are immediately obvious to the user. This manual provides practical help and information about ChessBase. The author has deliberately concentrated on topics that are particularly useful or in need of explanation. Beginners are thus guaranteed a quick start. Advanced users will benefit from the detailed explanations of selected topics.
