IMPORTANT NOTE: This book contains most of the opening variations as defined by ECO codes (which covers more than 2000). It's NOT a comprenhensive list of ALL chess opening theory and ECO (Encyclopedia of Chess Openings) contains both "good" and "bad" opening variations. ECO is the global standard for classification of chess opening variations - it does *NOT* judge quality of openings. Just like the ISBN system of books does not judge quality of normal books.
You need to understand standard chess notation for chess moves to be able to use this app.

Permissions of SD-card read/write is used for storage of temporary position diagrams and pgn files.
