ECO B: Semi-Open Games Traps

Semi-Open Games Traps are those classified under code B and subcategories B00-B99: Semi-Open Games other than 1…c5.

Serving as a comprehensive classification system, the Encyclopaedia of Chess Openings (ECO) categorizes chess openings through unique codes, where each code corresponds to a specific chess opening or variation. Comprising letters (A to E) and numbers, these codes provide a structured and thorough approach to cataloging the broad spectrum of chess openings. The ECO system finds extensive use in chess literature and databases, aiding in the systematic organization and recognition of various opening sequences.

Highlighting the primary role of the ECO system as a reference in chess literature, databases, and tournament reports for communication and opening classification, it is justified to employ this system for categorizing Semi-Open Games Traps.
