Grigor Grigorov launches a new long-term training concept in February 2026 — Repertoire Builder: Réti for White – Fundamental Structures after 1.Nf3 d5 2.g3.
This camp marks the starting point of a six-month Opening Builder journey, designed for players who want to build a real, durable repertoire — not a collection of memorized lines. The focus is on understanding structures, plans, and decision-making from the very first move.
We begin with the most classical and principled response to 1.Nf3. The positions reached after 1.Nf3 d5 2.g3 lead naturally to Réti- and Catalan-type structures, where central tension, piece coordination, and long-term plans matter far more than concrete theory.
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, flexible White repertoire that remains relevant regardless of theoretical fashion.

June & July – Repertoire Construction Phase
With a strong structural foundation in place, the final phase focuses on:
• Choosing concrete move orders
• Resolving practical “if–then” decisions
• Minimizing theory through intelligent transpositions
• Assembling a complete, coherent 1.Nf3 repertoire
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.
