Synopsis "The Universe of Chess Positions. Mapping the PC - TC - AC"
The Universe of Chess Positions - Mapping the PC-TC-AC Worlds Every chess position belongs to one of three fundamental worlds. Learning to recognize them changes everything. PC (Position/Calm) - the world of Capablanca. Stable structures, quiet improvement, long-term planning. TC (Transition/Contact) - the world of Petrosian. Pawn tension, prophylaxis, the decisive moment before the breakthrough. AC (Attack/Chaos) - the world of Tal. Open lines, sacrifices, forced calculation, total war. Inspired by the theoretical work of Alexander Shashin, the PC-TC-AC system gives you a complete diagnostic method: identify the positional world in under 3 seconds, choose the right plan, and recognize the transitions that decide the outcome of the game. What you will find in this book: - A clear typology of the three positional worlds (Chapters 1-4) - Instant diagnosis and transition recognition (Chapters 5-6) - Training routines including AI-assisted analysis (Chapter 7) - Strategic synthesis and practical application (Chapters 8-10) - 60 illustrated motifs (20 PC, 20 TC, 20 AC) with diagrams - 20 fully annotated games from Capablanca to the FIDE Candidates 2026 Whether you are an intermediate player looking for a structured approach or an experienced competitor seeking a universal framework, this book provides the missing map. The right plan in the right world - that is the key to everything. François Chevalier (AIM Arena, FIDE) has been playing chess for over 40 years. A geographer and chartered accountant by training, he brings a unique analytical perspective to positional chess theory.
