Key Variations & Typical Setups
Opening Summary
Black challenges the d4 pawn immediately with ...c5, aiming for counterplay on the queenside and central tension without committing to ...Nf6 or ...e5 yet. White typically seizes space with d5, but Black’s structure remains flexible and ready for either Czech- or Modern-style plans.
Main Move Order
The Old Benoni is defined by 1.d4 c5. White usually replies with 2.d5, claiming space. Black’s replies include ...d6 (Classical), ...e5 (Czech transposition), ...Nf6 followed by ...e6 (Modern), or flexible fianchetto plans with ...g6.
Main Classical Line — 2...d6 3.e4 Nf6 4.Nc3 g6
After 1.d4 c5 2.d5 d6 3.e4 Nf6 4.Nc3 g6 5.Nf3 Bg7 6.Be2 O-O, Black achieves a harmonious King’s Indian-like setup with the pawn on c5 instead of c6. Plans revolve around ...b5, ...a6, ...Re8, or ...Nbd7, while White leverages space. Evaluation: slightly better for White (+0.3) but fully playable for Black.

...d6and...e5solidity. - Tal – Keres, 1959 (training) — White uses space and
f4–f5ideas. - Uhlmann – Larsen, 1973 — showcases modern
...b5/...f5counterplay. - Karpov – Ljubojević, 1985 — positional squeeze against the Old Benoni.

- 2.d5 e5: Czech Benoni transposition — dark-square focus.
- 2.d5 Nf6 3.c4 e6: Modern Benoni transposition — dynamic.
- 2.d5 g6: Fianchetto system — Benoni–KID hybrid.
- 2.c4 cxd4 3.Qxd4: Symmetrical English-type — offbeat and flexible.

...b5,...f5, dark-square control. - Typical Transpositions — Czech/Modern Benoni, King’s Indian.

- Modern Evaluation — ≈ Equal; rare but sound weapon.
Summary: The Old Benoni challenges White from move one, offering flexibility to transpose or remain independent. Black’s counterplay on dark squares and flanks turns the space deficit into long-term pressure — ideal for strategists who prize structure and timing.
