GM Grigor Grigorov continues the six-month Opening Builder project in September 2026 — Repertoire Builder: French Defense for Black – Fundamental Structures after 1.e4 e6 2.d4 d5 3.Nc3.
This is the second stage of a journey designed for players who want to build a real, durable repertoire — not a collection of memorized lines. The focus remains on understanding structures, plans and decision-making rather than accumulating theory.
August established the foundation: the closed French pawn chain of the Advance Variation, the ...c5 break at its base, and the long-standing question of the light-squared bishop. September turns to White's most principled continuation.
With 3.Nc3, White develops and keeps every option open — and hands Black a choice that shapes the rest of the game. The lines that follow produce a different family of structures from the Advance: positions where White closes the centre on his own terms, where the fight moves to the wings, and where the value of each minor piece depends entirely on which pawn structure has been reached.
Theory is kept intentionally light — only what is required to reach the right kinds of middlegame positions. The emphasis is not on memorizing sequences, but on understanding what ideas work, what each side is playing for, and how plans emerge naturally from structure.
A central idea of Opening Builder is that openings are not an isolated phase. They are a gateway to the middlegame. By focusing on fundamental structures from the very start, you learn to enter the middlegame with clarity, confidence and a clear sense of direction.
This training is ideal for players who want a strategic, resilient Black repertoire against 1.e4 that remains relevant regardless of theoretical fashion.
August Fundamental Structures after 1.e4 e6 2.d4 d5 3.e5 The closed French pawn chain — the ...c5 break, pressure on d4, and the light-squared bishop.
September Fundamental Structures after 1.e4 e6 2.d4 d5 3.Nc3 White's most principled continuation, and the structures that follow from it.
October Fundamental Structures in the Winawer – 3.Nc3 Bb4 Dark-square strategy, the doubled c-pawns, and the imbalances that make the Winawer one of the richest structures in chess.
November Fundamental Structures against the Tarrasch, the Exchange and the sidelines Isolated and hanging pawn positions, symmetrical structures, and the practical setups Black meets when White declines the main battlegrounds.
December & January – Repertoire Construction Phase
With a strong structural foundation in place, the final phase focuses on:
This phase transforms understanding into a ready-to-play system suitable for long-term competitive use.

Opening Builder is not about "winning the opening."
It is about entering the middlegame with understanding — knowing what you are playing for, and why your position makes sense.
By the end of six months, participants do not simply know lines. They possess a living repertoire — grounded in structures, adaptable to change, and resilient against theoretical trends.
This is opening preparation — the Modern Chess way.
This event is completed.
