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.

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.
