| The purpose of Chess Informants Encyclopaedia of Chess Openings is to offer an extensive coverage of all the relevant opening lines (including a myriad of obscure ones) in sufficient detail to provide end-users with enough information to employ them in contemporary tournament practice. Since the book should appeal both to over-the-board and correspondence chess players who often need exceptionally detailed material that can stand the test of time, this calls for a rhetoric question, what does it really take to produce a new edition of a volume of Encyclopaedia of Chess Openings? It is generally considered that an opening encyclopaedia should set the standard for opening theory as a reliable reference manual at the time of its release. However, the enormity of games available in commercial databases makes the task extremely difficult, especially in the most fashionable lines, where grandmaster evaluations (as published in the Informants, for instance) often become overrun by a multitude of games from recent tournament practice, or even refuted. Therefore, all the material inherited from the previous edition invariably undergoes serious re-examination, where critically-minded humans from the Chess Informant Editorial Board join forces with top computer engines in the process of rebuilding foundations for the new coming lines, which often leads to completely new problems, and a chaos inevitably ensues. Alas, a clear-cut structure should be maintained, which calls for tough decisions and painful compromises in order to fit everything into ECO tables and the accompanying footnotes. To make a long story short, I should just add that the new Volume is expected to bring 56 pages more than the preceding one. However, the space devoted to each ECO code is generally in proportion to its popularity in current practice, with minor exceptions only. During the past five years D 10 (1. d4 d5 2. c4 c6 without Nf3) has reached the peak of popularity, which resulted in a sharp (probably the most extreme) increase in the surveyed material: 86 lines and 455 footnotes (24 pages), make a world of difference in comparison with the 16 lines and 79 footnotes (6 pages) covered in the third edition. Our readership is treated to a fragment of the highly topical line of the Slav Defence: 1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. e3 a6 5. Qc2 b5. For the sake of presentation, the material previewed in the article covers the concluding seven lines (rows 80-86) in the D 10 ECO table only. |
