In 1931, Max Euwe and José Raúl Capablanca reached a position where Black had just sacrificed the exchange on a8. Capablanca, with the black pieces, stood better — and never realised it, repeating moves into a draw he should have been pressing to win.
Nearly a century later, that same position is the critical theoretical battleground of this repertoire. White's most testing engine moves still lead straight back to it, and Black is still playing for three results. That is the spirit of the whole course: principled, fighting, and built on lines that reward the player who understands them.

Few openings announce their intentions as openly as the Exchange Slav. After 1.d4 d5 2.c4 c6 3.cxd5 cxd5, White releases the central tension and accepts a symmetrical pawn structure. For most of its history this has been read as a peace offering: trade early, simplify, and steer toward a dry position where Black's best case is half a point.
Exchange Slav for Black — Top-Level Repertoire sets out to overturn that reading. Its premise, in GM Vladimir Malakhov's words, is that symmetry is not the same as a quiet life — Black can answer every White setup with positions that keep real winning chances on the board.

When IM Filip Pancevski took up the King's Indian Defence at age 12, he couldn't have imagined he'd still be wielding it more than two decades later—through database explosions, engine revolutions, and countless theoretical novelties. Yet here we are. The KID has survived every computational assault not because the positions are "objectively equal" (they often aren't), but because the resulting chaos favors the player who understands the ideas over the one who memorizes computer lines.

GM Baadur Jobava and GM Andrea Stella continue their King's Indian Defense series for Black with a complete repertoire against the Makogonov 5.h3 — the flexible system Carlsen, Caruana, and Giri reach for when they want to squeeze without overextending. Across 11 chapters, the course offers clear structural plans for every White setup, with several rare lines that take Black off the database by move eight.

The Slav Defense has long held a unique status among Black's responses to 1.d4—a reputation for solidity without passivity, resilience without concession. While other defenses against the Queen's Gambit force Black into early structural commitments or passive piece placement, the Slav allows natural development and maintains central tension.
GM Mahammad Muradli's Slav Defense — Full Repertoire for Black delivers a complete, practical repertoire centered on the Classical Slav with 4...dxc4, designed for players who value long-term reliability over short-term fashion.

Twenty years of practical refinement, now brought to completion. GM Vladimir Malakhov, one of the world's foremost Chebanenko experts, returns to finish what Part 1 began.
Where the first volume covered White's most critical tries—5.c5, 5.e3, and 5.g3—this second part closes every remaining door. The anti-Chebanenko systems, the sidelines, the move-order tricks that strong players use to avoid main theory: all of them are met with concrete solutions.
This is not supplementary material; this is the completion of a professional repertoire that has weathered decades of grandmaster practice.

For decades, the great unsolved question of 1. For decades, the great unsolved question of 1.d4 d5 has been everything that isn't 2.c4. Dreev and Basso solve it through a unified Black system built on principle rather than memorization, anchored by a revolutionary new idea against the London. The third volume completing the authors' QGD series — and the final piece of a comprehensive repertoire against every first move White can choose.

The Queen's Indian Defense has long been chess's quiet answer to 1.d4 — a hypermodern system where Black controls the center from a distance rather than occupying it directly. Yet for decades, players seeking active counterplay gravitated toward sharper systems like the King's Indian, treating the Queen's Indian as a fallback option.
GM Mitrabha Guha challenges that assumption head-on. In his debut Modern Chess course, the Indian grandmaster presents the Queen's Indian not as a drawing weapon, but as one of the rare Black openings where you can genuinely play for the win against 1.d4. His repertoire is built around 4...Bb7 rather than the more forcing 4...Ba6, emphasizing deep positional understanding over memorization — a choice that makes the opening both more resilient and more instructive.

When a grandmaster opens a course with the words "This variation has been my faithful companion for my entire chess life," you know you're not looking at a trendy theoretical experiment. GM Vladimir Malakhov has played the Chebanenko Slav in World Championship qualifiers, Olympiads, and blitz sessions alike—and it has never let him down.
Now, together with GM Pier Luigi Basso, he's built a two-volume series to share this repertoire with the chess world. Part 1 tackles the main battlegrounds: the systems White employs in the vast majority of games at every level.

When Alexey Dreev began working on this course, he wasn't just thinking about opening theory—he was thinking about what players actually face over the board. The Queen's Gambit Declined with ...Be7 is one of the most reliable defensive systems in chess, but surviving the main lines with Bf4 and Bg5 is only half the battle.
The real preparation challenge lies in navigating the extensive landscape of sidelines, tricky move orders, and practical tries that club players and professionals alike deploy with increasing frequency. This course addresses that gap directly.
