Benoni Defense: all variations and ECO codes

61 named lines across 24 ECO codes (A40–A79). Source: the CC0-licensed lichess.org opening database.

The idea

Black meets White’s central space grab with an early c5, and once the position settles - typically after ...e6, d5, and an eventual ...exd5 cxd5 - trades the e-pawn rather than the c-pawn, leaving White a protected passed pawn on d5 in exchange for Black’s own queenside pawn majority and open lines for active piece play. It’s a much sharper bargain than the solid, symmetrical structures most other replies to 1.d4 aim for.
