The Paulsen Sicilian has long been a weapon of choice for players who want to outplay their opponents from a position of strategic complexity. Black's setup with ...a6 and ...e6 is deceptively flexible — it avoids early commitments while preparing a rich middlegame where initiative often shifts gradually. For decades, White's responses were either sharp and double-edged or solid but uninspiring. GM Jose Martinez Alcantara and IM Dragos Ceres propose something different: 5.Bd3, a move that is flexible, concrete, and immediately sets the terms of the game.

For most of its history, 3…Nd4 in the Ruy Lopez has been the kind of move that earns a raised eyebrow rather than serious theoretical concern. GM Mahammad Muradli's starting point for this course is a simple observation: the same idea in the Rossolimo Sicilian is an entirely different story. After 1.e4 c5 2.Nf3 Nc6 3.Bb5 Nd4, Black sidesteps conventional theory entirely, gaining initiative, active piece play, and a pawn structure White has almost never faced before at a practical level. This course provides a full Black repertoire built around that idea — concrete, thoroughly prepared, and almost entirely off the theoretical map.

For over a century, the Scheveningen Sicilian has stood as one of Black's most resilient answers to 1.e4—championed by Kasparov, analyzed by generations of world-class players, yet often sidelined in recent years due to the aggressive Keres Attack (6.g4). GM Pier Luigi Basso's latest course dismantles that hesitation. Rather than treating the Keres as an obstacle, Basso reframes it as the central battlefield where the Scheveningen reveals its true character: meeting flank aggression with precise central counterplay. The message is clear—stop fearing the Keres, start playing the Scheveningen the right way.

When preparation obsession reaches its peak in modern chess, the strongest players seek not just good positions, but positions their opponents haven't studied. GM Luis Paulo Supi's third and final installment of his Sicilian repertoire introduces a deceptively simple concept: strategic postponement. After 1.e4 c5 2.Nf3 Nc6, instead of committing immediately with 3.Bb5 (Rossolimo) or 3.d4 (Open Sicilian), White plays 3.Nc3—a move that appears modest but fundamentally reshapes Black's decision-making process.
The brilliance lies not in the move itself, but in what it denies. Black cannot enter the Sveshnikov. The Taimanov and Four Knights players find themselves steered into unfamiliar territory. Even the Accelerated Dragon enthusiast must reconsider, as White has carefully retained the option to transpose—or to avoid transposition entirely. This is chess as a psychological weapon: your opponent knows the main lines, but suddenly those lines are unavailable, and the alternatives feel uncomfortable.

The Grivas Sicilian—characterized by the early 4...Qb6—has long existed in the shadow of mainstream Open Sicilian theory. For decades, strong players dismissed it as interesting but ultimately insufficient, particularly after White's most testing responses. GM Boris Avrukh, one of the world's foremost opening theoreticians, believed the same. Until he didn't.

The Taimanov Sicilian has long been considered one of Black's most sophisticated defensive systems—flexible enough to adapt to White's setup, solid enough to withstand direct attacks. World champions and super-GMs have trusted it for decades precisely because it doesn't commit too early. But what if White could force commitment? What if a single move could eliminate Black's most natural developing square and create immediate concrete problems?
GM Jose Martinez Alcantara and IM Dragos Ceres answer this question with 7.g4—a bold, space-grabbing approach that transforms the entire character of the position. This isn't speculative aggression; it's a modern refinement of classical attacking ideas, backed by deep concrete preparation and recent elite-level practice. By practically ruling out ...Nf6, White forces Black into uncomfortable territory where every alternative setup carries specific structural or tactical drawbacks. The authors build on their successful collaboration from Najdorf for White - Top-Level Repertoire, extending their aggressive vision across the entire Sicilian landscape.

IM Kushager Krishnater's Crushing The Sicilian - Grand Prix Attack offers a repertoire built on 2.Nc3, deliberately avoiding the main battlegrounds where Black's preparation runs deepest. This isn't a system for players seeking quiet games—it's a weapon for those who want to dictate the battle while their opponents navigate unfamiliar terrain. The course philosophy centers on aggressive setups grounded in sound positional principles, targeting practical players who understand that superior preparation often outweighs theoretical objectivity.

Magnus Carlsen, Nihal Sarin, Hikaru Nakamura—when top players need a Sicilian that combines solidity with dynamic potential, they turn to 2...Nc6. This seemingly simple move order has quietly become one of the most sophisticated weapons in modern tournament practice, offering Black the strategic flexibility of the Sveshnikov. GM Brandon Jacobson's new course builds a complete repertoire around this pragmatic yet ambitious approach, showing how 2...Nc6 serves as the gateway to dynamic play in both the Open Sicilian and the Rossolimo.

For decades, Sveshnikov specialists have been the hunters—armed with sharp preparation, steering opponents into forcing lines where concrete knowledge decides the game. But what happens when you're sitting on the Black side of a Rossolimo and White is the one avoiding your preparation? GM Baadur Jobava and IM Dragos Ceres reverse the script in Anti-Sveshnikov Sicilian - Top-Level Repertoire for Black, presenting 3...e5 as Black's answer to the Rossolimo: a move that sidesteps White's most rehearsed plans and shifts the battle back to understanding over memorization.

GM Baadur Jobava and IM Dragos Ceres have produced Part 2 of their Sveshnikov project with a specific mission: to arm Black players with a complete, deeply analyzed repertoire against White's most dangerous modern tries. Where most databases offer superficial coverage of one or two variations after the critical position following 9.a4 Be7, this course dedicates six full chapters to this single branch alone. The authors dissect 10.Be2, 10.Be3, 10.a5, 10.b4, and 10.Bd2—each requiring distinct defensive setups and counterattacking ideas.
