Courses (60)

The first volume of a new six-month project, and it begins where the French itself begins: the Advance Variation and the archetypal pawn chain of d4 and e5 against d5 and e6, from which almost every strategic idea in the opening can be traced — the ...c5 break at the base, the pressure on d4 with ...Qb6 and ...Nc6, and the long-standing question of the light-squared bishop. GM Grigor Grigorov devotes two full lectures to the structure itself before any concrete line, then turns to the closed positions after 6.a3 c4 and the sharp gambit lines after 6.Bd3 cxd4. Theory is kept intentionally light — the aim is to enter the middlegame knowing what you are playing for, not to memorise sequences.

The final volume of the six-month Réti project, and the one that completes the system. Where Theoretical Knowledge, Part 1 answered everything Black tries with ...d5, Part 2 takes on the whole remaining field: the Réti Slav and the Tarrasch Defence, the Hedgehog and double fianchetto, the Dutch in both its Leningrad and Stonewall forms, the Symmetrical English and the Wedberg System, the King's Indian Fianchetto — and the ...g6 setups, met with a clear decision to play 2.e4. Theory is given where theory is required, but always on top of the structures built across the first four months, which is why it can be absorbed quickly rather than memorised painfully.

After four months of studying the fundamental structures of the 1.Nf3 complex — Réti and Catalan-type formations, King's Indian and Grünfeld structures, English Opening positions with symmetrical setups, Hedgehog formations and Maróczy-type structures — we are now ready to translate that understanding into concrete theoretical preparation.
In this phase, theory is no longer kept light. We look at concrete move orders and specific variations, where precise theoretical knowledge is required. The bet the whole project has been making is cashed in here: with the typical ideas and structures already familiar, the theory is absorbed quickly rather than memorised painfully.
This first half of the theoretical part covers all Black setups involving the move ...d5.
The material is based on the camp of the same name and is now transformed into a complete digital product, including full video recordings of all lectures, a structured PGN file following the logic of the training sessions, and extensive theoretical analysis for deeper study.

The Opening Builder – Réti for White: Fundamental Structures after 1.Nf3 c5 2.c4 is the fourth part of our six-month Réti project. It continues the work started in the first course on the structures after 1.Nf3 d5 2.g3, the second on 1.Nf3 Nf6 2.c4 e6 3.g3, and the third on 1.Nf3 Nf6 2.c4 g6 3.Nc3.
This part addresses what happens when Black meets our move order with the most independent try of all — 1...c5, steering the game into the English Opening complex. These are among the most flexible and strategically rich positions in modern chess: symmetrical setups, Hedgehog formations, and Maróczy-type structures, all of which are central to a 1.Nf3 repertoire and all of which reward deep structural understanding rather than concrete preparation.
The material is based on the camp of the same name and is now transformed into a complete digital product. It includes full video recordings of all lectures, a structured PGN file that follows the logic of the training sessions, and additional model games and theoretical examples for further study.

The third part of our six-month Réti project, covering everything after 1.Nf3 Nf6 2.c4 g6 3.Nc3. A complete repertoire against the Grünfeld Defence and the King's Indian Defence, built on understanding pawn structures rather than memorizing variations.

The second part of our six-month Réti project, covering everything after 1.Nf3 Nf6 2.c4 e6 3.g3. A complete repertoire against the Queen's Gambit Declined, the Queen's Indian Defence, and the Hedgehog, built on understanding pawn structures rather than memorizing variations.

The Opening Builder – Réti for White is not a traditional opening course. It is the starting point of a structured six-month project, designed for players who want to build a repertoire based on understanding rather than memorization.
Instead of learning long variations, the focus is on reaching the right structures and knowing how to play them.
The material is based on the February edition of the Repertoire Builder camp, now transformed into a complete digital product, including:

The chess world has witnessed a curious paradox in recent years. While opening theory explodes in complexity across the Sicilian, French, and Caro-Kann, the classical 1...e5 has quietly evolved into what FM Or Cohen calls "an island of stability in modern opening theory." This seven-volume project, co-authored with GM Grigor Grigorov, challenges the fashionable notion that Black must sidestep central confrontation with moves like 1...e6 or 1...c6. As GM Jan Gustafsson memorably put it: "I have a hard time believing in moving a pawn one square like 1...e6, 1...c6, 1...g6, etc. The center is there, fight for it!"

When GM Michael Roiz began developing his comprehensive Nimzo-Indian repertoire, he recognized that after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4, White's fourth move determines the strategic language of the entire game. Part 1 addressed 4.Qc2 and 4.e3, while Part 2 tackled 4.f3, 4.a3, and 4.g3. Yet a critical gap remained: White's most popular choice in contemporary practice, 4.Nf3.
Nimzo-Indian Defense According to Roiz – Part 3 closes this circle, completing the trilogy with a thorough examination of 4.Nf3 and rare alternatives. The centerpiece is the theoretically dense 5.g3 Catalan system, where White's setups blend Catalan structure with Nimzo-Indian tactics.

When GM Michael Roiz surveyed the modern Nimzo-Indian landscape, he observed that while 4.e3 and 4.Qc2 dominate tournament practice, three ambitious sister systems—4.f3, 4.a3 (Sämisch), and 4.g3—remain strategically interconnected yet theoretically underserved.
Part 2 of his Nimzo-Indian Defense According to Roiz series addresses precisely this gap, offering Black a coherent positional framework across these critical lines. This course doesn’t merely catalog variations—it builds a unified strategic language for navigating White’s most aggressive central setups, from Gheorghiu’s bold 4.f3 to Petrosian’s patient Sämisch approach and the Catalan-flavored 4.g3.
