Benoni Defense
Move Sequence
d4— Queen's pawn.♞f6— Indian defense.c4— Flank setup.c5— Benoni! Black provokes d5 at once with a deeply asymmetric structure.d5— White goes with the plan: clamping d5 and gaining space.
The Benoni Defence begins with 1.d4 ♞f6 2.c4 c5 3.d5 — Black typically meets 3.d5 with 3...e6, after which 4.♞c3 exd5 5.cxd5 d6 6.e4 g6 produces the Modern Benoni. The name "Benoni" comes from Hebrew and means "son of sorrow" — an allusion to Black's difficult position. The opening is double-edged and leads to tense, unbalanced games.
Typically 7.♞f3 ♝g7 8.♝e2 O-O follows, establishing the characteristic Benoni structure.
Strategy
The Benoni creates a highly asymmetric pawn structure: White has a central pawn majority (d5 and e4), Black has one on the queenside (a7, b7 — lever b5). The fianchettoed bishop on g7 targets the entire centre. Black aims for the advance b7-b5 for queenside counterplay and to open the game in favour of active pieces. This opening is a battle between two different plans on opposite sides of the board.
Typical Continuation
After 8.♝e2 O-O play often continues 9.O-O a6 10.a4 (White prevents b5) or 10.♞e1 with the manoeuvre ♞e1-d3 for the push e4-e5. Black tries to generate counterplay with ♞e8-d6-b5 or f7-f5-f4. The Benoni is dangerous at amateur level because it offers concrete attacking plans. It is, however, theoretically demanding and requires understanding both sides.
Suitable for: Aggressive / risk-taking — for players who seek unbalanced positions with their own counterattack.
