1...d6 universal - Minimal Prep, Maximum Understanding
Victor Bologan
Why memorising endless theory might not be the best path - and how an idea-based repertoire can change your game.
The concept is simple but powerful: choose systems for both White and Black that revolve around typical pawn structures and recurring piece setups. That way, you’re not learning dozens of different openings - you’re learning one flexible idea that applies across many positions.
In this first course focused on Black, we build our repertoire around the solid and compact d6–e5 structure:
• Against 1.e4: We play the Philidor setup, offering rich positional play and quick piece development.
• Against 1.d4 and other closed systems: We aim for flexible development, with our dark-squared bishop either on e7 or g7, while keeping our eyes on the central break with ...e5.
This setup is not only effective but easy to learn, highly resilient, and surprisingly tricky for opponents unfamiliar with its subtleties. I’ve played it my whole life - in blitz, rapid, and even classical tournaments - and it has served me well.
In fact, my recent success in a Fischer Random tournament was largely due to my comfort with pawn structures and strategic flexibility - not memorised lines.
With this course (and the upcoming companion repertoire for White), you won’t just get a practical, low maintenance opening solution. You’ll build a deeper understanding of chess that helps you:
• React confidently in unfamiliar positions
• Make better decisions based on ideas, not memorised moves
• Save time while still staying competitive
Learn smart. Play smart. Let’s build your opening repertoire the lazy way - with lasting understanding, not short-term memory.
