King’s Pawn Game: all variations and ECO codes

38 named lines across 5 ECO codes (B00–C44), spanning ECO volumes B, C. Source: the CC0-licensed lichess.org opening database.

The idea

The shared starting point for every reply to 1.e4 gathered under one ECO code before Black’s actual answer sorts the game into a named family of its own - not a strategy in itself so much as the root every open game, semi-open defense, and irregular try against 1.e4 branches from.
