ECO D: Closed Games Miniatures

Closed Games Miniatures are those classified under code D and subcategories D00-D99: Closed Games and Semi-Closed Games.

The Encyclopaedia of Chess Openings (ECO) functions as a classification system, systematically arranging chess openings into distinct codes. Each code represents a specific chess opening or variation and is composed of letters (A to E) and numbers. This systematic approach provides a comprehensive means of cataloging the vast array of chess openings. Widely adopted in chess literature and databases, the ECO system aids in the organized identification of various opening strategies.

An important consideration is that the ECO system functions primarily as a reference tool in chess literature, databases, and tournament reports, streamlining communication and the categorization of openings. Thus, it is apt to employ this system for classifying Closed Games Miniatures.
