At the top level, the French has drifted toward equality. The fashionable 7...cxd4 8.Nxd4 Qb6!? is now mapped so deeply that many games are decided before the middlegame begins.
GM Felix Blohberger builds his repertoire around a different idea — steering Black into lightly explored positions where both sides still have to play real chess. The emblem of that approach is a move you will rarely find in a database: 7...h6!?, preparing the disruptive ...g5 break.

After a catastrophic 25-move defeat to Smyslov in the 1954 World Championship match, Botvinnik did what he always did: he went home and studied. He emerged with a single quiet king move, 7...Kf8, and uncorked it against Unzicker at the Amsterdam Olympiad that same year. Every modern engine now confirms it as the best continuation in the line — a verdict Botvinnik reached decades early, armed with nothing but a board and the discipline to interrogate his own loss.
That moment is the spine of the fourth and final volume of GM Pier Luigi Basso's Understand the French series, and it points to what this course is really after. The lesson isn't the move — it's the method that produced it. With Rubinstein, Petrosian, and Korchnoi, you could study a player and adopt his repertoire. Botvinnik is loyal to specific systems even when they are dubious, even when they cost him games against Tal, so copying him is not the point. Learning how he thought — and worked — is.

There is a familiar trade-off behind every solid opening: depth costs time. The Caro-Kann is famous for its reliability, but reaching top-level fluency in it has traditionally meant working through hundreds of pages of theory. Caro-Kann Express for Black is built on the opposite premise — that a complete, tournament-ready repertoire can be delivered without cutting the quality of the recommendations. This is not a lightweight repertoire built from scratch; it is drawn from a complete deep series and trimmed to the lines that actually decide tournament games.

For decades the Exchange Caro-Kann was filed under "harmless" — a line to sidestep theory and split the point. Then Magnus Carlsen and Hikaru Nakamura began reaching for it at the very top, and the reassessment was immediate. Mahammad Muradli's new course, The Exchange Caro-Kann with 4.Bd3 for White, builds a full repertoire around exactly what those players saw in it.
The idea is a Carlsbad-type structure reached with an extra tempo, where White presses with the familiar attacking plans without the usual preparatory cost — and without ever diving into forced theory.

The Berlin Defense is one of the most fascinating and historically rich openings in chess. Renowned for its solidity and the challenges White faces in finding new ideas, the Berlin Defense has become so effective that it has even caused many players to reconsider the traditional Ruy Lopez. In this course, Pier Luigi Basso aims to equip you with a reliable and rock-solid repertoire, but not one that simply settles for a draw—this course will show you how to play for a win!

Ask an experienced Caro-Kann player where the half-points actually leak away, and the answer is almost never the main lines. It is the quiet second move nobody revised in a while — the Fantasy, the King's Indian Attack, an offbeat 2.Ne2 — where preparation thins out and a comfortable position quietly drifts into something worse.
Across a long career, few players have done more to give the Caro-Kann its modern standing than GM Alexey Dreev. In this final volume he turns that authority to exactly the parts of the opening most repertoires leave half-finished.

Löwenthal, O'Kelly, Nimzowitsch, Grivas and others — the Sicilian's minor roads are paved with the names of players who wanted no part of a theoretical main line. Each found a way to sidestep the Najdorf and the Sveshnikov and reach a position where preparation runs thin and the game is decided by understanding rather than memory. They are easy to underestimate, and that is exactly the problem: the half-points that slip away against a sideline you half-remember are the ones that quietly hold a rating in place. Sicilian Arsenal for White is the volume that answers all of them.

Sometimes a single move, played almost in passing by an elite grandmaster, contains more poison than a thousand pages of established theory. When GM Luis Supi watched GM Nodirbek Abdusattorov reach for 7.Be2 against the Sveshnikov Sicilian, his first reaction was disbelief. He knows this opening as well as anyone, yet here was a move he had never seriously considered — and the more he searched for a refutation, the clearer it became that there wasn't one. What looked like a casual sidestep turned out to be a genuine, and currently underrated, way to fight one of Black's most reliable defences.
