Benoni: 3.dxc5 — Anti-Benoni sideline
Benoni: 3.dxc5
Definition
Benoni: 3.dxc5 refers to the anti-Benoni line that arises after the moves 1. d4 Nf6 2. c4 c5 3. dxc5. Instead of entering the quintessential Benoni structure with 3. d5, White simply captures on c5, side-stepping Black’s typical counterplay based on ...e6, ...d6, ...g6, and ...b5 breaks. This “pawn-grab” is a practical weapon to neutralize the dynamic character of the Benoni Defense and to steer the game toward calmer, often more symmetrical, positions.
Because Black almost always regains the pawn (commonly via ...e6 and ...Bxc5 or the move-order trick ...Na6 and ...Nxc5), this line is sometimes nicknamed a “Benoni Accepted” setup, although that label is informal. In opening Theory, it is considered a solid sideline for White aimed at denying Black the trademark Benoni pawn structure.
Typical Move Orders and Main Ideas
Common routes to the position and Black’s most reliable ways to recapture the pawn:
- 1. d4 Nf6 2. c4 c5 3. dxc5 e6 4. Nf3 Bxc5 5. e3 O-O 6. Be2 Nc6 — Black restores material balance and aims for ...d5 or ...d6 with harmonious development.
- 1. d4 Nf6 2. c4 c5 3. dxc5 Na6!? 4. Nc3 Nxc5 — A move-order finesse. Black avoids an early ...e6 and recaptures with the knight to keep options flexible.
- If White tries to cling to the extra pawn with b2–b4, Black typically replies with ...a5!, undermining the chain and regaining the pawn with activity.

How It’s Used in Chess
Players choosing 3. dxc5 want to:
- Avoid the sharpest Benoni middlegames and typical kingside storms.
- Lead the game into more balanced structures resembling a Queen’s Gambit Accepted or symmetrical English-type position with colors reversed.
- Test a Benoni devotee’s Home prep and move-order knowledge; a single inattentive move can hand White a pleasant, risk-free edge.
Black, as a Benoni player, uses 3...e6 (regain with ...Bxc5) or 3...Na6 (regain with ...Nxc5) to ensure smooth development and often strikes in the center with ...d5 or ...d6 followed by ...e5 or ...b6–...Bb7. Correct handling typically equalizes and restores the dynamic balance Benoni players seek.
Strategic Themes
For White:
- Development-first: Refrain from overextending to “save” the c5-pawn; aim for quick Nf3, e3, Be2, O-O, and place rooks on d1/e1.
- Central breaks: Keep an eye on the e4 advance (supported by Re1 and Qc2), especially if Black delays ...d5.
- Space without risk: Make Black prove full equality; small edges often come from improved piece activity and safer king.
For Black:
- Clean recapture plan: Use either ...e6 and ...Bxc5 or ...Na6–...Nxc5 without losing time.
- Counterplay choices: Strike with ...d5 in one go if possible; otherwise set up ...d6 and consider ...e5 or breaks on the queenside with ...b6–...Bb7.
- Pressure on e-file: After ...e6 and ...Bxc5, the e-file often opens; coordinate rooks to challenge e3/e4 ideas.
Transpositions and Pawn Structures
The capture on c5 frequently transposes to structures familiar from the Queen’s Gambit Accepted or the Symmetrical English (with colors reversed). Typical features:
- Balanced central tension: ...d5 from Black or e4 from White can reshape the center.
- Symmetry with a twist: Both sides often castle short; minor pieces maneuver to d2–c4 or d6–e5 squares, and the rooks contest open files rapidly.
- If Black gets in ...d5 comfortably, equality is the norm; if Black hesitates and drifts, White can claim a pull thanks to faster development and a firmer center.

Common Pitfalls and Mini-Traps
- White overprotects c5 too ambitiously: 1. d4 Nf6 2. c4 c5 3. dxc5 e6 4. b4? a5! undermines the pawn chain; after ...axb4 Black wins back c5 with tempi and activity.
- Black delays the recapture and drifts: If Black plays slow moves without ...e6/…Na6, White can consolidate with e3, Nf3, Bxc4, O-O, and seize a comfortable edge.
- Misplaced piece trades: Swapping the light-squared bishop too early can leave Black soft on e6/d6 squares; conversely, an ill-timed e4 by White can be met by ...Bb4+ or ...d5 freeing Black.

Theoretical Status and Practical Use
Currently, engines (Engine) tend to evaluate the main lines close to equality (roughly 0.00 to a few centipawns in either direction), reflecting the solid, low-risk character for White and the reliable equalizing resources for Black. As a result, 3. dxc5 is a legitimate practical weapon when you want to avoid heavy Benoni main-line Book and still keep good Practical chances. It appears in OTB play, but is also popular in Rapid and Blitz where move-order nuances can pay dividends.
Illustrative Example Line (With Plans)
This line shows both sides developing naturally and the key ideas of central breaks and queenside expansion:
- White’s plan: Solid setup with e3, Be2, O-O; prepare b4–Bb2 to influence the long diagonal and consider e4 if feasible.
- Black’s plan: Timely ...d5 or ...d6 followed by ...e5; piece pressure on the e-file and activity for the bishops often neutralize White’s pull.
Interesting Facts and Anecdotes
- Psychological jab: Many dedicated Benoni players love the asymmetrical, combative pawn structure after 3. d5; 3. dxc5 “declines the fight,” which can be a mild psychological win for White.
- Move-order tricks: The flexible 3...Na6!? is a favorite of experienced Benoni practitioners to regain c5 without committing to ...e6, sometimes dodging White’s pet lines or specific Home prep.
- Practical weapon: In fast time controls, this line serves as an effective Drawing weapon or surprise choice to take an opponent out of heavy Book move territory.
Training Tips
- As White: Don’t get greedy. Develop swiftly; if Black hits your c5-pawn with ...Na6 or ...e6, be ready to return it and play for structure and activity.
- As Black: Choose your recapture scheme early. If you play ...e6, be poised for ...Bxc5 and a quick ...d5; if you opt for ...Na6, monitor the c5 square and keep central breaks in view.
- Use Engine checks but trust principles: Smooth development and timely central breaks matter more than trying to “refute” this solid sideline.
Quick Reference Summary
- Move order: 1. d4 Nf6 2. c4 c5 3. dxc5.
- Core idea: Sidestep dynamic Benoni structures; aim for safer, more symmetrical play.
- Black’s equalizers: ...e6 with ...Bxc5, or ...Na6 with ...Nxc5; timely ...d5 is thematic.
- Evaluation: Theoretically sound for both sides; engines usually hover near equality (small CP swings).
- Best use cases: Surprise weapon, solid repertoire choice to avoid heavy Benoni main lines.
