There is an old saying among French Defense devotees: the real game begins once the theory stops. Unlike many sharp openings where preparation decides the outcome, the French rewards — and punishes — understanding. A player who has memorized 20 moves of the Advance Variation but cannot explain why White's e5-pawn is both a strength and a vulnerability will eventually be outplayed by someone who has studied the structure itself. This is precisely the insight behind Understanding the French Defense, a new course by GM Davorin Kuljasevic published on Modern Chess.

Few structures in chess generate such radically different plans for both sides as the doubled c-pawns arising from the Nimzo-Indian Defense. White accepts a compromised pawn formation in exchange for the bishop pair, space, and dynamic potential — while Black banks on long-term structural pressure and endgame technique. This tension between different advantages is what makes the Nimzo-Indian one of the richest strategic battlegrounds in modern chess, and precisely why it deserves systematic, structure-by-structure treatment.

In the golden age of positional chess, masters like Nimzowitsch and Petrosian built their reputations on a deceptively simple principle: restrict your opponent's possibilities first, then execute your own plan at leisure. This strategic philosophy—often called prophylaxis or restraint—remains one of chess's most elegant yet underappreciated concepts. GM Ioannis Papaioannou's How to Find the Right Plan revives this classical approach with modern precision, teaching players to identify and exploit long-term assets across all phases of the game.

Inside Your Games – Edition 2 is not a course about perfect moves.
It is a course about real thinking, in real games, under real conditions.
As GM Ioannis Papaioannou explains, the goal of this project is simple but rare:
to show how a strong player evaluates positions, forms plans, and makes decisions — not how a chess engine assigns numbers to moves.

Most players know their rating but not their actual chess profile. A 2300 might calculate like a 2500 in tactical positions, then drop to 2100 when handling strategic imbalances. A 2450 converts technical endgames at 2600 strength but freezes in critical moments, playing more like 2250. GM Alexey Dreev and GM Pier Luigi Basso built 100 Moves to 2700 – The 2026 Edition to expose these hidden discrepancies—turning vague self-assessment into concrete, actionable data about where your chess truly lives.

Blohberger's approach addresses the most common struggle in competitive chess: what to do once the opening ends and familiar territory disappears. Rather than offering a collection of tactical motifs or abstract strategic principles, the course teaches systematic thinking through pawn structure analysis, piece improvement, and positional evaluation. The Austrian grandmaster, winner of the Modern Chess Autumn Challenge, previously created a comprehensive treatment of 1.c4 e5 for Black. Now he shifts focus from opening preparation to the middlegame phase where games are truly decided.

Inside Your Games – Edition 1 is a premium diagnostic training product built around 15 real games played by members of the Modern Chess Academy and analyzed in depth by GM Ioannis Papaioannou. These are not polished model games chosen for aesthetic value. They are authentic tournament games, containing the typical inaccuracies, wrong plans, and critical decisions that decide games at the board.
The goal of this project is simple but ambitious:
to teach you how to think better in real positions, not how to memorize perfect moves.

GM Swapnil Dhopade's October Tactical Thursday course examines two interconnected aspects of advanced chess understanding: strategic calculations and positional sacrifices. This four-part study addresses a common gap in player development—the ability to calculate not merely for tactical gain, but to verify the soundness of long-term positional ideas.

GM Ioannis Papaioannou's latest Strategy Wednesday course addresses one of chess's most fundamental yet frequently misunderstood strategic concepts: pawn majorities. This four-part examination traces how pawn majority advantages are established in the opening, exploited through the middlegame, and converted in the endgame.
The course synthesizes practical examples from diverse opening systems—the Caro-Kann, Colle System, Nimzo-Indian, Modern Benoni, French Defense, Catalan, and Réti—demonstrating that pawn majority patterns transcend specific repertoires. Each structure presents distinct strategic challenges: when to advance your majority, when restraint proves superior, and how to transition positional advantages into technical wins.

There's a paradox at the heart of chess mastery that GM Efstratios Grivas confronts directly in the second part of his exploration on exchanges: the decisions that seem most mechanical—trading piece for piece—are often the most consequential. While beginners learn arithmetic values and apply them rigidly, strong players understand that the real value of pieces fluctuates with every move. Grivas builds his teaching on a deceptively simple principle: "Only exchange pieces for a good reason." This course examines the intricate logic behind when to trade and, perhaps more critically, when to refrain from exchanges.
