Code ECO
The code ECO (abbreviation of Encyclopedia off Chess Openings ) is an internationally recognized system of classification of the openings to the Jeu of failures.
The system of grading
A code ECO is composed of the letter has, B, C, D or E followed by two digits, 00 to 99.This system is at the base of the international Notation (or Notation figurine), in which specialized Pictogramme S replace the explanations in vernacular languages.
This system allows the publication of a review: the Adviser of the failures (usually called the Adviser in the world échiquéen) comprehensible by any amateur, it does not matter his language. He also allowed the broad diffusion of a series of encyclopedias and monographs on the failures.
The Encyclopedia of the openings of failures
The most known realization is the Encyclopedia off Chess Openings (or Encyclopédie of the openings of failures ) in 5 volumes (has, B, C, D, E), and which knows regular updates.-
has characterizes the initial blows others that 1.e4 and 1.d4 (+ Défense Benoni and Dutch Défense).
- B characterizes the answers to 1.e4 other than 1… e5 and 1… e6.
- C characterizes the beginnings 1.e4 e5 + 1.e4 e6 (French Défense).
- D characterizes the 1.d4 beginnings whose answer is not 1… Cf6 (+ Défense Grünfeld).
- E characterizes the beginnings 1.d4 Cf6 2.c4
It is the same system which is used in the triennial review, the Informateur of failures (98e number in April 2007), published by the same editor. More generally, the system was spread in all the community of the players of failures. Thus, the French review Europe-Failures uses it in the classification of all the parts which it publishes.
