The Ultimate Bulletproof Repertoire for Black – Part 1: The Damiano Defense
Authors: FM Or Cohen & GM Grigor Grigorov
🚨 We are thrilled to present the first volume of a groundbreaking repertoire series—The Ultimate Bulletproof Repertoire for Black after 1.e4 e5. In this first installment, FM Or Cohen and GM Grigor Grigorov team up to offer a surprising, deeply analyzed, and conceptually sound weapon—the Damiano Defense: 1.e4 e5 2.Nf3 Nf6 3.Nxe5 Nxe4!?
♟️ While the Damiano has traditionally been seen as dubious, this course demonstrates—with unprecedented depth—that it is a fully playable and highly practical opening in the age of NNUE engines and refined chess understanding. FM Or Cohen has spent nearly two decades perfecting this line, which he considers an alternate Berlin—a reliable system that frustrates 1.e4 players by forcing quiet, technical battles.
🧠 This course stands out not only for its content but also for its training methodology.

🧩 The Bigger Picture – What Comes Next?
This course is just Volume 0 of a seven-part series. Here’s a sneak peek at the roadmap:
-
Volumes 1A & 1B: All White deviations from 2.Nf3, including the Vienna, Bishop’s Opening, King’s Gambit, Center Game, 2.d4, and more
-
Volumes 2A & 2B: The Petroff Defense after 3.Nxe5 d6 and 3.d4 Nxe4—covering minor and mainlines in great detail
-
Volumes 3A & 3B: Hardcore Petroff lines, including the endgame variations and lesser-known sub-systems like the Jacob Murey Defense
🛡️ Why Start with the Damiano?
While the Petroff will eventually form the core of this repertoire, the Damiano allows you to start playing 1.e4 e5 immediately—with confidence and surprise value. FM Or Cohen believes that the Damiano can be used as a serious weapon at all levels, with the added psychological bonus of throwing off aggressive 1.e4 players expecting traditional defenses.
💡 The Damiano Compensation – A recurring theme throughout the repertoire is the idea of giving up a pawn for long-term dynamic equality or the bishop pair. You’ll see this motif again in future courses. The goal is not to avoid equality, but to embrace it as a weapon—a way to drag opponents out of their comfort zone and into unfamiliar, technical positions.
👥 Who Is This For?
This course is designed for ambitious players rated 1700+, up to and including professionals. The PGN file is incredibly detailed, ideal for serious preparation. The videos are practical, clear, and tailored for quick implementation. Players below 1700 are welcome to watch and experiment—but the full power of this system shines for those with strong fundamentals and positional understanding.
🧠 The Modern Approach to Opening Preparation
In the era of engine-equalized openings, Cohen emphasizes that winning doesn’t come from memorization alone. This course teaches you how to frustrate opponents, play technically, and simplify into better positions. It’s a mindset—pragmatic, grounded, and practical.
🗂️ Customizable & Modular
Use the PGN to create your own tournament-ready 1...e5 repertoire. You can adapt, shorten, or simplify lines to suit your style and level. Whether you play the Petroff or 2...Nc6, the material is flexible and extensive.
✨ This is not just an opening course—it’s a chess project years in the making. A labor of love. A declaration that 1...e5 is still the king of defenses—and now, even the Damiano belongs in your toolkit.
