Scandinavian Defense for Black – Top-Level Repertoire March 29, 2026

Scandinavian Defense: A Complete Repertoire for Black Against 1.e4

Challenging the Center Before It Forms

There is a moment, familiar to every 1.e4 player, when the opponent refuses to follow the expected script. Instead of conceding the center, Black strikes immediately with 1…d5 — and after 2.exd5 Qxd5, places the queen on a5: not passive, not exposed, but strategically active from afar. This is the Scandinavian with 3…Qa5, and it is precisely this queen placement that defines the opening’s character. Its main practitioner at the elite level is Shakhriyar Mamedyarov, who has built a complete weapon around it against the world’s best.

GM Sina Movahed’s course presents a unified system: 1.e4 d5 2.exd5 Qxd5 3.Nc3 Qa5, followed by …Nf6 and …Bf5 — a setup also used by Nodirbek Abdusattorov. Every major White try is covered, from the trending 3.h3 (employed by players like Shimanov, Duda) to the sharpest critical lines involving 6.Ne5 and 7.Bc4, giving Black a coherent answer at every turn.

A Repertoire Built on Elite Practice

What distinguishes this course from a theoretical script is the quality of the source material. Movahed traces each White deviation to its top-level practitioner: Christiansen’s 4.g3, Aronian’s 4.Bc4, Nakamura’s gambit with 4.b4, Gukesh’s 6.Bc4. Knowing who plays a line, and why, gives each variation a face and a purpose — making the material far easier to understand and remember.

Those familiar with Movahed’s previous course — the Blumenfeld Gambit: Top-Level Repertoire for Black — will recognize his combative approach to Black’s repertoire. Against 1.d4, he offered a sharp, fighting weapon. Here, he goes a step further: a complete answer to 1.e4, covering every major White try from the rarest sidelines to the sharpest critical lines.
