The Modern Philidor Defense – 2025

Where Classical Resilience Meets Contemporary Precision

When François-André Danican Philidor declared “pawns are the soul of chess” in 1749, he could hardly have imagined that his eponymous defense would endure centuries of skepticism only to emerge as a thoroughly modern weapon.

The 1…d6 setup—once dismissed as passive—has been reborn through engine analysis and high-level practice as a flexible, resilient system that poses concrete problems even at the elite level.
The Modern Philidor Defense – 2025, by GM Baadur Jobava and GM Pier Luigi Basso, now enhanced by the distinguished addition of GM Vladimir Malakhov, represents the defense’s full evolution: not merely solid, but strategically rich and tactically dangerous.

A New Author, A New Dimension

This second edition introduces a major enhancement: GM Vladimir Malakhov’s “Opening Understanding” section, featuring six carefully selected Philidor games annotated in his distinctive instructional style.
Renowned for his profound positional sense, Malakhov goes beyond memorization — he shows how to think in Philidor structures, why certain plans succeed, and when to deviate from established theory.
These annotated games serve as the conceptual backbone of the course, immersing students in the defense’s logic before engaging with concrete variations.

Jobava and Basso — who previously collaborated on The Norwegian Variation against the Ruy Lopez and The Practical Benko Gambit — have comprehensively restructured the theoretical chapters.
The most significant expansion concerns the critical 5.Rg1 system — once a single chapter, now unfolded across four detailed ones.
This reflects both the line’s current popularity and the authors’ commitment to offering bulletproof preparation against White’s sharpest attempts.

Technical Architecture

The course delivers a complete Philidor repertoire through 17 chapters, systematically organized by White’s main setups:

• The classical main line with 7.a4;

• The instructive Philidor endgame arising after early queen exchanges;

• Shirov’s aggressive 5.g4;

• The modern 5.Rg1 complex (now treated in depth across four chapters);

• And additional systems with f3, Bd3, and Nge2.
