For GM Alexey Dreev, the Sicilian has never been a phase but a lifelong choice. He has played 1...c5 throughout his career, and among all its branches he considers the Classical Variation the most healthy one.
His reasoning is simple. Black develops naturally, fights for the centre and plays for a win, without the volume of forced theory that surrounds the Najdorf. What the Classical demands instead is understanding.
The Rauzer: There Is No Way Around It
Anyone who plays 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 Nc6 knows which move comes next most often: 6.Bg5, the Richter-Rauzer Attack. As Dreev puts it, a Classical Sicilian player will meet it in every second game.
That is why Part 1 of this repertoire is devoted entirely to 6.Bg5. Black answers with 6...e6, the classical main line. It requires real knowledge, but it gives a repertoire built to last, one that can be played against any opponent.

After 1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 a6, White faces probably the most theoretical position in chess. Millions of games have been played, and the main lines are analyzed deep into the middlegame.
Finding something fresh here is a real test. That is the task of this stage.
This database continues the Modern Chess Autumn Challenge. In the Carlsbad stage, four authors built repertoires for Black. Now the challenge switches sides: GM Baadur Jobava, GM Lorenzo Lodici and GM José Martínez Alcántara received the same task, a repertoire for White against the Najdorf. Each of them worked on it independently.

Few positions have been studied as deeply as the Carlsbad. After 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.cxd5 exd5 5.Bg5, White's plans have been known for more than a century: the minority attack with b4-b5, or f3 followed by e4.
That is exactly what makes it a hard test. When everyone knows the plans, Black needs more than general understanding. Black needs a concrete repertoire.
This database is the next stage of the Modern Chess Autumn Challenge. For this stage, GM Tomás Sosa, FM Sebastian Reimann, GM Jan Subelj and IM Ajay Santhosh received the same task: a repertoire for Black against the Exchange Variation with 5.Bg5. Each of them worked on it independently.
Four recommendations. No two alike.

For decades, the Symmetrical English was valued above all for its solidity. Black mirrors White's development, and the question has always been when, and how, to break the symmetry.
GM Mitrabha Guha gives a clear answer. In the modern main line, 1.c4 c5 2.Nf3 Nf6 3.Nc3 Nc6 4.g3 g6 5.Bg2 Bg7 6.d4 cxd4 7.Nxd4, Black plays the surprising 7...h5!?.
The point is concrete. Black provokes h2-h3, and that pawn will often end up hanging. A mirror-image opening turns into a fight with a clear target.

This course, Part 2 of The Modern Caro-Kann, offers a complete Black repertoire against the Advance Variation, built around GM Szymon Gumularz's ambitious 7...c4!? in the Short System, which keeps pieces on the board and plays for a win rather than settling for a theoretical endgame. Across 15 chapters, it provides concrete answers to every major White setup after 1.e4 c6 2.d4 d5 3.e5 Bf5, guided by the principle that Black should never settle for equality when a fighting alternative exists.

Every French player knows the moment. You brace for the theoretical fights of 3.Nc3, and instead White slides the knight to d2 or simply trades on d5. These are not attempts to refute your opening — they are attempts to drain it of life. The Tarrasch and the Exchange are the practical player's tools: low theory, low risk, and built on the quiet hope that Black will grow bored, passive, or both.
GM Andrea Stella and GM Pier Luigi Basso built this fourth and final part to reject that bargain. Their repertoire takes the two lines French players meet quite often and reframes them as positions Black plays for a win — not through wild complications, but through a chain of deliberate second choices that keep tension exactly where the mainlines offer symmetry.

Ask a hundred Accelerated Dragon players why they gave the opening up, and most will point to the same reason: the Maroczy Bind. White plants pawns on c4 and e4, controls d5 twice over, and settles in for the slow, space-heavy game where Black spends many moves — ...Nxd4, ...a5-a4, ...Qa5 — just to earn the right to stay level.
A lot of players look at that prospect and quietly switch openings. GM Pier Luigi Basso's The Maroczy System with ...Qb6 is built for the ones who would rather make White answer first.

For a hundred years, the French has been the opening where the defender knows the ground better than the attacker. The Winawer and the Steinitz have been mapped move by move for generations, and the French specialist arrives at the board expecting White to be the first to run out of memory. The French 3.Nc3: A Complete Repertoire for White was built to reverse that expectation.
The method is not to out-analyse a century of theory but to step around it. In every principal line the repertoire turns toward positions with a few hundred games in the database rather than tens of thousands — places where understanding the plan matters more than recalling the next fifteen moves, and where Black is left to think independently remarkably early.

After 1.d4 Nf6 2.c4 e6 3.Nf3 c5 4.e3 d5, the game reaches an isolated queen's pawn structure that belongs to no single opening — the very same positions arise from the Panov Attack, the Semi-Tarrasch, the Queen's Gambit Declined and the Symmetrical English, so learning to handle them once pays off for the rest of your career. Across seven lectures, GM Ioannis Papaioannou begins with two full sessions on the attacking ideas and technical procedures of the structure itself, then builds the concrete repertoire on top: the immediate 4...d5, the Panov tabiya after 5.exd4 d5, and Black's attempts to stay flexible.

More than almost any other opening, the French is defined by its endgames — the middlegames flow again and again into the same recurring family of positions, and the player who understands them holds a lasting edge over the one who merely reaches them. Across four lectures, GM Ioannis Papaioannou covers the typical endings of the Advance, Tarrasch, Winawer and Exchange variations: the isolated-pawn structures and the critical light-squared bishop trade, the d4/e5 pawn chain, and the doubled c-pawns of the Winawer and MacCutcheon.
