The Eternal Ragozin Defense - Part 2 
Discounted

When GM Mahammad Muradli completed his first Ragozin course covering the critical lines with 5.Bg5 and 5.Qa4+, a natural question emerged: what about everything else? The Ragozin's unique structure—combining Queen's Gambit Declined themes with the Nimzo-Indian pin—creates a position where White's knight on c3 becomes a tactical anchor rather than an active piece. This fundamental difference shapes all of White's sideline attempts, and understanding how to exploit it transforms these "quiet alternatives" into comfortable positions for Black.

Triangle Slav for Black - Part 2 
Discounted

When GM Valery Kazakouski and GM Pier Luigi Basso released Triangle Slav for Black - Part 1, they armed club players and professionals alike with the Marshall Gambit and the Noteboom—two aggressive systems where Black seizes the initiative from the opening moves. Now comes the natural question: what happens when White declines the confrontation? When they choose e3 instead of accepting complications, when they opt for Catalan structures or other "quiet" setups hoping to neutralize Black's ambitions?

Triangle Slav for Black - Part 2 answers this question with a bold proposition: transform these supposedly calm positions into a superior version of the Stonewall structure. The key insight is simple yet profound—by reaching the f7-f5 structure through the Triangle Slav move order, Black obtains a Stonewall where White's pawn is already committed to e3. This seemingly small detail fundamentally alters the character of the position. Where traditional Stonewall setups often struggle against White's space advantage and piece pressure, this version gives Black cleaner development, better piece coordination, and genuine winning chances.

Practical 1.d4 Repertoire According to Dhopade - Slav, Semi-Slav, and QGA 
Discounted

When facing 1...d5, White players often find themselves juggling multiple repertoires—one system for the Queen's Gambit Declined, another for the Slav, yet another for the Semi-Slav. GM Swapnil Dhopade's latest course offers something different: a coherent strategic framework that treats these Black defenses not as separate entities requiring distinct preparation, but as variations of a single narrative. By employing g3-setups across the board, Dhopade creates what might be called a "Catalan philosophy" even in positions where Black has committed to ...c6—bringing the benefits of the fianchetto's long-term positional pressure to structures traditionally associated with sharper theoretical battles.

Play the Catalan - Part 1 - 2025 Edition 
Discounted

When Alexey Dreev first championed the Catalan at the highest level, he didn't just play an opening—he refined a philosophy. Now, in partnership with GM Pier Luigi Basso, that philosophy evolves. Play the Catalan - Part 1 - 2025 Edition arrives exactly one year after their original course, not as a replacement, but as a strategic evolution shaped by elite practice and theoretical earthquakes at the top level.

Jobava London According to Jobava - Part 1 - 2025 Edition 
Discounted

When GM Baadur Jobava first introduced 1.d4 d5 2.Nc3 Nf6 3.Bf4 in 2013, he compared the opening to "a lady I had fallen in love with." For years, he guarded his secrets jealously, watching others publish courses that relied on engine evaluations rather than capturing the opening's true spirit. In 2024, he finally shared his complete vision with Modern Chess. Now, just one year later, the Jobava London returns—not as a static system, but as a living, breathing organism that continues to evolve with modern chess.

Semi-Slav Defense - Arsenal for Black 
ArsenalDiscounted

The Semi-Slav has earned a reputation as one of the most principled and strategically rich answers to 1.d4. GM Alexey Dreev’s flagship course Semi-Slav Defense According to Dreev established the main-line foundation of the entire 5.e3 complex. However, modern chess demands more. Opponents increasingly try to surprise early with fifth-move sidelines—positions that are theoretically independent and require concrete preparation.

With Semi-Slav Defense – Arsenal for Black, GMs Alexey Dreev and Vladimir Malakhov finally complete the system. This course provides Black with a full, deeply analyzed arsenal against all deviations from the main lines, delivering both theoretical clarity and practical understanding through model games, thematic examples, and strategic patterns.

The Eternal Ragozin Defense - Part 1 
Discounted

The Ragozin Defense offers something different—a synthesis that feels almost too good to be true. After 1.d4 Nf6 2.c4 e6 3.Nf3 d5 4.Nc3 Bb4, Black develops naturally, pins the c3-knight, and maintains constant tension in the center. The position breathes with possibilities: tactical strikes with ...c5 or ...dxc4, strategic maneuvering around the isolated queen's pawn structures, and endgames where Black's activity compensates for any positional drawbacks. It's a system where understanding the character of positions matters more than memorizing computer lines—precisely the kind of opening that rewards players looking for practical variations to play.

Bogo-Indian Defense with ...Qe7 for Black 
Discounted

The Bogo-Indian Defense has long carried a reputation for being solid but passive—a reliable drawing weapon rather than a path to active play. GM Alexey Dreev and GM Pier Luigi Basso challenge this perception fundamentally. Their course centers on a philosophical shift: the classical 4...Qe7 line, dismissed for years as too quiet, contains dynamic potential that modern engine analysis has only recently revealed.
This isn't about memorizing twenty-move sequences. It's about grasping the structural logic that makes the Bogo-Indian work—knowledge that transfers across your entire opening repertoire. Dreev's insight is elegant: when understanding replaces memorization, Black reaches "active, reliable positions that are also very easy to play."

Triangle Slav for Black - Part 1 
Discounted

This first volume of Triangle Slav for Black by GM Valery Kazakouski and GM Pier Luigi Basso focuses on the system's sharpest variations: the Marshall Gambit (4.e4 dxe4 5.Nxe4 Bb4+ 6.Bd2 Qxd4) and the Noteboom Variation (4.Nf3 dxc4 5.a4 Bb4). These aren't positional abstractions; they're practical battlegrounds where precise calculation matters more than general plans.

Jobava's Benoni Defense - Fight the Anti-Benoni Systems 
Discounted

The Benoni player's dilemma is well-known: you prepare sharp tactical lines after 1.d4 Nf6 2.c4 c5 3.d5, only to face 2.Nf3, 2.Bf4, or the slow positional grind of White's fianchetto setup. Suddenly, your preparation seems irrelevant. But what if the Benoni's essence—dynamic play, creative counterplay, and fighting chess—could be maintained regardless of White's move order? This is the philosophy behind Jobava's Benoni Defense - Fight the Anti-Benoni Systems by GM Baadur Jobava and IM Dragos Ceres, the continuation of their successful Jobava's Ambitious Benoni Defense - Part 1.
