Sozin Attack – Top-Level Repertoire for White PGN Only May 8, 2026 Modern Chess

The Sozin Attack: Fischer’s Favorite Returns to Elite Play

When GM Vidit Gujrathi sat down to face Alireza Firouzja at the Candidates 2024, he didn’t reach for the safe repertoire choices that dominate modern preparation. He played 6.Bc4 — the Sozin Attack — and Firouzja’s surprise was visible.

The line Fischer and Kasparov wielded as a weapon had become a rarity at the absolute top. But rarity isn’t the same as refutation. As Vidit proved, and as GM Jose Martinez Alcantara and IM Dragos Ceres demonstrate throughout this course, the Sozin remains one of the most concrete and dangerous systems White can employ against the Najdorf and Classical Sicilian structures.

Why the Sozin Disappeared — and Why It’s Back

The Sozin Attack (1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bc4) makes no compromises. The bishop points directly at f7, White prepares rapid kingside attacks, and the threat of opposite-side castling with Qd2-O-O-O keeps Black under constant pressure.

But modern defensive resources — especially the …Qb6 systems that put immediate pressure on d4 — convinced many players the Sozin had been “solved.” Martinez Alcantara and Ceres show that the opposite is true.

Their repertoire, built around 7.Nb3 and the critical 8.Bf4 tempo against d6, brings the Sozin into 2026 with fresh analysis, concrete improvements, and practical clarity against all of Black’s major defenses.

Variation Map: The Complete Sozin Structure

After 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 6.Bc4:

6…Qb6 — The Critical Qb6 System
→ 7.Nb3 e6 8.Bf4 and now:

• 8…Ne5 (main line) 9.Be2 a6 10.Qd2 → Chapters 2-4
• 8…Qd8 (Firouzja’s Candidates sideline) → Chapter 1

6…e6 — The Classical Mainline
→ 7.Be3 and Black chooses:

• 7…Be7 (direct development) 8.Qe2 → Chapters 5-6
• 7…a6 (Scheveningen setup) 8.Qe2 → Chapters 7-8

6…Bd7 — The Pragmatic Try
→ Preparing …Na5 to neutralize the Bc4 → Chapter 9

6…e5 — The Dreev Line
→ Ambitious central strike with structural concessions → Chapter 10

6…g6 — The Dragon Setup
→ Converting the Sozin bishop into a lasting attacking asset → Chapter 11

What Makes This Course Different

Martinez Alcantara brings analysis forged at the highest level — his preparation against Firouzja’s own Qb6 weapon forms the backbone of Chapters 1-4. Ceres contributes the structural clarity that makes the Sozin approachable: after 8.Bf4 in the Qb6 lines, White gains a tempo on d6 while preserving all the classic Sozin ideas (Qd2-O-O-O, opposite-side attacks, concrete tactical pressure).

The course doesn’t promise easy wins. It promises what the Sozin has always delivered: sharp positions where preparation and understanding decide the outcome. If Black knows the theory, the positions are balanced. If Black doesn’t, they face immediate practical problems.

The authors are collaborating on a broader project — the Jospem versus the Sicilian series — building a complete White repertoire against all Sicilian systems. The Sozin forms the aggressive centerpiece.
