Old Benoni: Queen's Pawn Opening
Old Benoni
Definition
The Old Benoni is a queen’s pawn opening that begins with 1. d4 c5. Unlike the Modern Benoni (which typically arises after 1. d4 Nf6 2. c4 c5), Black challenges White’s center with ...c5 immediately, often leading to a space-grabbing pawn on d5 for White and an unbalanced, counterattacking struggle for Black. It is considered a provocative, less common choice that can transpose into other Benoni families or remain a distinct structure.
How it is used in chess
The Old Benoni is primarily used as a surprise weapon. At top level it appears infrequently because early ...c5 concedes space after 2. d5, and precision is required to generate sufficient counterplay. In practical play—especially rapid and blitz—it is a viable way to avoid heavy theory and steer the game into asymmetrical positions with chances for both sides.
Basic move orders
-
Main idea: 1. d4 c5 2. d5. Now Black chooses among several plans:
- 2... Nf6 3. c4 e6 4. Nc3 exd5 5. cxd5 d6 (transposes to the Modern Benoni structure).
- 2... e5 (directly heading for the Czech Benoni structure with ...d6, ...e5).
- 2... e6 3. e4 exd5 4. exd5 d6 (the Franco–Benoni setup: ...e6 without ...Nf6 yet).
- 2... g6 3. e4 d6 4. Nc3 Bg7 (a fianchetto approach that can transpose to Modern Benoni or certain King’s Indian-style positions).
- White alternatives on move 2 include 2. c3 (aiming for a solid center with e4) or 2. dxc5 (rare and modest). The main test is 2. d5.
Strategic ideas and pawn structures
After 1. d4 c5 2. d5, White often builds a broad center with c4 and e4, while Black aims for counterplay on the dark squares and the queenside. The hallmark Benoni pawn chain for Black is pawns on d6 and c5 facing White’s e4–d5–c4 chain. Black’s counterplay usually revolves around ...b5 (queenside expansion), pressure on the e4 pawn, and piece activity on the long diagonal after ...g6 ...Bg7. In Czech Benoni setups (...e5), the game becomes slower and more maneuvering, with ...f5 or ...b5 as thematic breaks.
Typical plans
-
Plans for White:
- Space advantage: Occupy e4 and c4, support d5, and restrict Black’s piece mobility.
- Kingside pressure: h3, Nf3, Be2/Bd3, and f4–f5 or e4–e5 to open lines toward the king.
- Queenside clamp: a4 to discourage ...b5; sometimes b4 or cxb5 to undermine Black’s counterplay.
- Piece maneuvers: Nd2–c4–e3/f3, Be2–g4/f3, and careful handling of the e4 pawn (tactics on the e-file are common).
-
Plans for Black:
- Queenside play: ...a6, ...b5, and ...Rb8 to open files and create counter-chances on the b-file.
- Dark-square control: ...g6, ...Bg7, ...Re8 to target e4; sometimes ...Na6–c7 to buttress ...b5 and hit d5.
- Central breaks: In Modern-type structures, ...e6 aiming for ...exd5 to relieve space; in Czech structures, ...f5 or ...b5 are critical pawn breaks.
- Piece activity: Timely ...Re8–Nbd7–Ne5 or ...Nh5–f4 can create dynamic kingside counterplay.
Typical tactics and motifs
- ...Re8 and pressure on e4: Tactics with ...Nxe4 can appear if White’s e4 is insufficiently guarded.
- ...b5 pawn break: Sacrificing a pawn to open the b-file or deflect c4 is a recurring resource.
- c4–c5 pushes (for White): Fixing Black’s queenside or opening the c-file at the right moment.
- Dark-square play: Bishops on g7 and c1 often become key attackers; watch for Bxh6 ideas for White and ...Bxc3 to damage structure for Black.
- Checks along the a5–e1 diagonal: ...Qa5+, ...Qh4+, or Bb4+ can appear after premature development by White.

Historical notes and significance
“Benoni” comes from the title of an 1825 treatise by Aaron Reinganum, “Ben-Oni,” a Hebrew phrase often translated “son of sorrow.” Historically, early ...c5 against 1. d4 was one of the original Benoni concepts—hence the moniker “Old” Benoni for 1. d4 c5. Today, while the Modern Benoni has a richer top-level pedigree, the Old Benoni remains a practical, offbeat choice that can transpose to modern systems or sidestep mainstream theory.
Model games in related structures include Fischer vs. Myagmarsuren, Sousse Interzonal 1967 (a celebrated Modern Benoni where White demonstrated a powerful kingside expansion). Although that game began with 1. d4 Nf6, the resulting structures are exactly those Old Benoni players often reach by transposition.
Transpositions and repertoire notes
- To the Modern Benoni: 1. d4 c5 2. d5 Nf6 3. c4 e6 4. Nc3 exd5 5. cxd5 d6, reaching a mainline Benoni.
- To the Czech Benoni: 1. d4 c5 2. d5 e5, with a closed, maneuvering battle.
- To the Franco–Benoni: 1. d4 c5 2. d5 e6 3. e4 exd5 4. exd5 d6, a solid shell with ...e6.
- King’s Indian flavors: With ...g6, ...Bg7 and ...d6 before ...Nf6, Black can steer toward KID-like development while preserving unique Benoni pawn play.
Practical tips
- For White:
- Claim space with c4 and e4; don’t allow easy ...b5—meet it with a4 or timely cxb5.
- Be ready for e4–e5 or f2–f4–f5 to punish slow kingside development.
- Watch the e4 pawn: overextension invites ...Re8 and tactical shots on e4.
- For Black:
- Develop quickly and aim for counterplay: ...a6–...b5, ...Re8, and piece pressure on e4/d5.
- Choose a clear plan early: Modern-type (...e6) or Czech-type (...e5); mixing plans can leave you cramped.
- Use piece maneuvers like ...Na6–c7 and ...Nd7–e5 to improve coordination before pawn breaks.

Interesting facts
- The Old Benoni’s rarity at elite level amplifies its surprise value; specialists like Sergei Tiviakov have explored related Czech Benoni setups effectively.
- Engines tend to give White a small edge out of the opening, but the practical complexity and imbalance often favor well-prepared Black players.
- Because move orders are flexible, many “Old Benoni” games transpose to Modern Benoni or King’s Indian structures, making it a versatile repertoire tool.
