The Encyclopedia of Chess Openings (or ECO) is a clas• sification system for the opening moves in chess. It is pre• sented as a five-volume book collection (now also a computer database) describing chess openings. The moves • were taken from hundreds of thousands of games between masters, from published analysis in the Chess Informant • since 1966, and then compiled by notable chess players. • The main editor is Aleksandar Matanović. Both the ECO and the Chess Informant are published by the Serbian company Šahovski Informator (Chess Informant). These openings are typically provided in an ECO table that con- 1.3 cisely presents the best opening lines.
