Encyclopaedia of Chess Openings is a multivolume reference work cataloguing chess openings and variations used by competitive players, theorists, and trainers. The set serves as a standard reference alongside works by Garry Kasparov, Bobby Fischer, José Raúl Capablanca, and Mikhail Botvinnik, and it is cited in tournament preparation by professionals affiliated with FIDE, European Club Cup, World Chess Championship, and national federations. Editors and contributors have included figures associated with Šahovski Informator, Everyman Chess, and major events such as the Candidates Tournament and the Chess Olympiad.

Overview

The encyclopedia organizes opening theory into volumes that present exhaustive move-order trees, assessment summaries, and example games drawn from play by masters like Viswanathan Anand, Magnus Carlsen, Vassily Ivanchuk, Anatoly Karpov, and Alexander Alekhine. As a tool it complements databases maintained by teams linked to FIDE World Cup, Linares International Chess Tournament, Tata Steel Chess Tournament, and engines developed by groups at Stockfish, AlphaZero, and academic projects at MIT and University of Texas. Players from clubs such as Marshall Chess Club, New York Chess Club, and academies associated with Soviet Chess School have historically used the resource.

History and editions

First published in the 1970s, the project grew from efforts by editors connected to Šahovski Informator and publications promoted at events like the Belgrade International Tournament and the Moscow International Tournament. Subsequent editions were revised after major matches including the World Chess Championship 1985 and the World Chess Championship 1990 and updated to reflect novelties introduced in encounters between grandmasters such as Viktor Korchnoi, Boris Spassky, Emanuel Lasker, and Wilhelm Steinitz. Later printings were issued by imprints including Everyman Chess and distributed at venues like Linares and Wijk aan Zee. Special editorial teams have drawn on game collections from databases maintained by ChessBase, The Week in Chess, and contributors from federations such as the Russian Chess Federation, All India Chess Federation, and United States Chess Federation.

Classification system and notation

The set is organized using an alphanumeric code scheme that assigns lettered volumes and numeric subcodes to openings and their branches, enabling cross-referencing with tournament bulletins from events like the Candidates Tournament 2020, Sinquefield Cup, and FIDE Grand Prix. Notation follows algebraic standards employed in periodicals such as Informator and by publishers including Pergamon Press and Batsford. The coding facilitates comparison with indices used in compilations by authors like Reuben Fine, John Nunn, Jeremy Silman, and match reports concerning players such as Paul Morphy and Samuel Reshevsky.

Coverage and organization of openings

Volumes cover principal branches: openings associated with names like the Ruy López, Sicilian Defence, French Defence, Caro-Kann Defence, Queen's Gambit, King's Indian Defence, Nimzo-Indian Defence, and English Opening. Each entry cites illustrative games from encounters at Candidates Tournament, World Rapid Championship, and national championships including the Russian Championship and the United States Championship. The set includes sidelines played by practitioners such as Richard Réti, Emanuel Lasker, Savielly Tartakower, Siegbert Tarrasch, and modern proponents like Veselin Topalov and Hikaru Nakamura; it arranges transpositions and move orders to aid preparation for matches at venues like FIDE World Cup and Chess Olympiad.

Influence and reception

The encyclopedia has been influential among professionals, trainers, and authors, shaping repertoires of champions including Anatoly Karpov, Garry Kasparov, Vladimir Kramnik, Viswanathan Anand, and contenders at events such as the Candidates Tournament and World Chess Championship 2018. Critics and historians referencing editions have included scholars associated with Oxford University Press and commentators from outlets like The Times and New York Times chess columns, and analyses by authors such as Nunn and Kasparov compare it with modern database-driven research. Debates over its comprehensiveness and the balance between human commentary and tabular lines have been voiced in forums linked to ChessBase, Internet Chess Club, and Chess.com.

Digital and online editions

Later editions and derivatives integrate with digital formats used by platforms like ChessBase, The Week in Chess, and services offered by Chess.com and Lichess. Data has been incorporated into engines developed by teams at Stockfish and research published by groups at DeepMind and Google; online dissemination occurs alongside broadcasts of events like Tata Steel Chess Tournament and FIDE Grand Prix. Licensing and editorial updates involve partnerships with publishers such as Everyman Chess and content providers behind databases used at World Chess Championship matches and major open tournaments.
