King’s Gambit Accepted: all variations and ECO codes

137 named lines across 7 ECO codes (C33–C39). Source: the CC0-licensed lichess.org opening database.

The idea

Black accepts the offered f-pawn, and the whole opening turns on whether White’s resulting lead in development and open f-file are worth more than the missing pawn. It’s one of the oldest tested tradeoffs in chess, producing sharp, tactical positions from move three onward rather than the slower buildup most other 1.e4 e5 openings favor.
