There is a moment, somewhere around move nine, when the Botvinnik System stops resembling chess as you know it. Pawns scatter, knights leap into chaos, and the board transforms into what Baadur Jobava himself calls a labyrinth — a position that "follows its own laws, its own rhythm." It was Mikhail Botvinnik who gave this variation its character in the mid-twentieth century, and decades later the theory remains alive, contested, and genuinely unsettled at the highest levels. That vitality is precisely what attracted two of the game's most creative minds to build a complete Black repertoire around it.

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.

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.

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.

When Alexey Dreev first adopted the Semi-Slav as a young Soviet master in the mid-1980s, the opening was respected but predictable. Forty years later, having played it through every phase of modern chess—from Soviet training halls to the engine era—Dreev has transformed his relationship with 1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 e6 from passive study into active co-authorship.
This new course, created together with GM Pier Luigi Basso, represents not just a repertoire but a living record of how the Semi-Slav has evolved—and how the two authors have shaped that evolution over the past decade.

The current database completes the survey of the Semi-Slav which was initiated by the previous database. The course consists of 11 theoretical chapters, 22 interactive test positions, a Memory Booster, and Video Version (4.5h Running Time).
The starting position of the database arises after 1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.e3 e6 5.Nf3 Nbd7 6.Qc2
In this database, Quintiliano makes a complete study of this move, which is called "Anti-Meran", although as we will see, the Meran ideas are always there. On the other hand, this move order offers some flexibility for White's plans and avoids the classical Meran lines (seen in the first database), which have been deeply analysed and can be more forcing.

The Semi-Slav defense is among the most popular openings for black against 1.d4. It is very flexible and usually leads to complex play in the middlegame. The name of the opening is logical since with 4...e6 black is playing a mix between the Slav and Queen's gambit declined (QGD).
In the present database, GM Davorin Kuljasevic provides you with a lifetime positional repertoire against this modern system.
