How Nimzo-Indian Players Can Meet 1.c4 + PGN March 26, 2026

When 1…Nf6 Becomes a Weapon: A Black Repertoire Against the English Opening

There is a long-standing paradox in repertoire building: the player who opens with 1.c4 is often trying to sidestep theory, yet the resulting positions can be just as complex and principled as what they hoped to avoid. GMs Pier Luigi Basso and Szymon Gumularz have built their new course around exactly this insight — rather than retreating into solid passivity, they arm Black with active, space-grabbing responses at every turn, turning the English into a battlefield of Black’s choosing.

The leitmotif is deliberate asymmetry. Where White seeks flexibility with 1.c4, Black replies with 1…Nf6 — preserving the same flexibility, but with concrete plans already in place. Against 2.Nc3, a critical try, the course recommends a central pawn sacrifice leading to lasting structural pressure on White’s doubled c-pawns. Against the Fianchetto (2.g3), Black grabs space with …d4 and plays for more than equality from the outset. Against the Réti (with 2.Nf3 3.b3), Basso and Gumularz offer a fresh recommendation involving an early …h5 — a modern approach not yet well-mapped in existing repertoire books.

What the Course Covers

The repertoire is structured across 10 chapters built around three main responses to 1.c4 Nf6. Against 2.Nc3, Chapters 1 and 2 examine the critical line after 2…e6 3.e4 d5 4.e5 d4 5.exf6 dxc3 6.bxc3 Qxf6, where Black has lasting pressure on the doubled c-pawns. Chapter 3 covers the 4.cxd5 exd5 5.e5 Ne4 sideline, and Chapter 4 handles the 3.Nf3 d5 4.e3 move order with its QGA transposition tricks. Against the Fianchetto, Chapters 5–7 develop the ambitious …d4 space-grab. Against the Réti, Chapters 8–10 cover the full 3.b3 complex, including the fresh …h5 recommendation in Chapter 8 and the 7.Bb5 main line in Chapter 10.
