For the better part of a century, the Rubinstein Variation (4.e3) has been White's most trusted answer to the Nimzo-Indian, and for one reason above all: it commits to nothing. The knight stays home on g1, waiting to choose between f3 and e2 until Black has shown his hand.
GM Alexey Dreev's answer is to out-wait the waiting move. At the heart of this repertoire sits a single, unassuming rook move — 5...Re8 — that hands the burden of commitment straight back to White. If the knight steps to f3, Black replies ...d6 and prepares the ...e5 break; if it goes to e2, Black switches to ...d5, where the e2-knight is awkwardly placed. Whichever square White picks turns out to be the wrong one. That is the "reload": an old main line given a new life, driven by move-order rather than memorization.

Reykjavik, 1972, Game 5. Boris Spassky plays the Nimzo-Indian's most popular system, and Bobby Fischer answers with an idea that looks almost careless: he captures on c3 without waiting for a3, voluntarily giving up the bishop pair. Then comes the point — ...d6, ...e5, and a blockade that slowly suffocates White's position. Twenty-seven moves later, Spassky resigns.
That blockading concept, refined by GM Robert Hübner in the late 1960s and 1970s, is the foundation of GM Mitrabha Guha's new course. Against the Rubinstein System with 4.e3 — by far White's most popular reply — Guha recommends exactly the Hübner treatment: 4...c5 followed by an early exchange on c3 and the strategic clamp with ...d6 and ...e5. It is a repertoire built on plans, not on memorizing long lines of theory.

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.

When Capablanca introduced 4.Qc2 against the Nimzo-Indian nearly a century ago, he established what would become the Classical Variation—a line respected for its soundness and strategic depth. Yet respect for a variation doesn't mean accepting drawn positions. GM Pier Luigi Basso and GM Szymon Gumularz return with Part 2 of their Nimzo-Indian series, completing what Part 1 began: a fighting repertoire built on elite-level preparation that refuses to surrender the initiative.

The Nimzo-Indian Defense isn't just surviving in 2026—it's thriving at the highest level. When rising stars like Praggnanandhaa, Gukesh, and Erigaisi consistently reach for the same opening with Black, the message is clear: this isn't nostalgia for Botvinnik's era, but a living, breathing weapon that delivers results against the world's best preparation. GMs Szymon Gumularz and Pier Luigi Basso have decoded exactly why these elite players trust the Nimzo-Indian, and their new course reveals the engine-approved concepts driving this renaissance.

For decades, White players facing 1.d4 Nf6 2.c4 e6 have confronted a fundamental dilemma: enter the heavily analyzed main lines of the Nimzo-Indian or Queen's Indian, where preparation often matters more than understanding, or deviate into sidelines that promise little objective advantage. GM Mahammad Muradli offers a third path with his new course on 3.Bf4 – a move that transforms the character of the struggle without sacrificing White's opening advantage.

When GM Michael Roiz began developing his comprehensive Nimzo-Indian repertoire, he recognized that after 1.d4 Nf6 2.c4 e6 3.Nc3 Bb4, White's fourth move determines the strategic language of the entire game. Part 1 addressed 4.Qc2 and 4.e3, while Part 2 tackled 4.f3, 4.a3, and 4.g3. Yet a critical gap remained: White's most popular choice in contemporary practice, 4.Nf3.
Nimzo-Indian Defense According to Roiz – Part 3 closes this circle, completing the trilogy with a thorough examination of 4.Nf3 and rare alternatives. The centerpiece is the theoretically dense 5.g3 Catalan system, where White's setups blend Catalan structure with Nimzo-Indian tactics.

When GM Michael Roiz surveyed the modern Nimzo-Indian landscape, he observed that while 4.e3 and 4.Qc2 dominate tournament practice, three ambitious sister systems—4.f3, 4.a3 (Sämisch), and 4.g3—remain strategically interconnected yet theoretically underserved.
Part 2 of his Nimzo-Indian Defense According to Roiz series addresses precisely this gap, offering Black a coherent positional framework across these critical lines. This course doesn’t merely catalog variations—it builds a unified strategic language for navigating White’s most aggressive central setups, from Gheorghiu’s bold 4.f3 to Petrosian’s patient Sämisch approach and the Catalan-flavored 4.g3.

The Nimzo-Indian Defense has long been one of chess’s most flexible openings — not because it’s vague, but because of the richness of its strategic options.
In this new course, GM Michael Roiz, together with GM Grigor Grigorov and IM Siegfried Baumegger, demonstrates that true flexibility requires depth — the ability to select systems that fit your style while maintaining concrete control of the position.
