Benoni Defense
ECO A56, A61 · 1. d4 Nf6 2. c4 c5
The Benoni Defense, 1.d4 Nf6 2.c4 c5 3.d5, accepts a space disadvantage in exchange for a queenside pawn majority and active pieces. The Modern Benoni (3...e6) is the sharpest version.
Plans for White
White plays e4, Nc3 and Nf3 with Bd3 or Be2, castles and aims for the e4-e5 break in the center, which can cut Black's position in two. Sharper systems with f4 (the Taimanov and Four Pawns Attack) try to blow Black away early.
Plans for Black
Black fianchettoes on g7, castles and expands on the queenside with ...a6 and ...b5, using the half-open e-file and the long diagonal. Pieces often go to e8 (rook), d7 or a6 (knight) and the queen to c7 or e7.
Typical pawn structures
After ...e6 and ...exd5 Black's pawn on d6 faces White's on d5, with a queenside majority for Black and a central majority for White. The d6 pawn and e5 square are the critical points.
Who it suits
Ambitious players who want unbalanced positions and dynamic counterplay and accept some structural risk.
Common traps
Timing is everything: an early e5 or Bb5+ can disrupt Black's development.
