This page introduces the core ideas behind how the Repertoire Builder is designed and how to use it most effectively. The platform favors a modular, line-based approach: study one variation deeply, keep things focused and compact, and let targeted tools (trainers, puzzles, analytics) do their best work.
Repertoire
A Repertoire is the core unit of the platform. It’s flexible — you can create repertoires for White or Black — but the recommended approach is to make each repertoire a single variation or line (rather than an entire colour). This keeps study focused and makes training, puzzles, and analytics precise and useful. Smaller, well-scoped repertoires are easier to maintain, faster to review, and simpler to improve over time.
- + Targeted learning — trainers and puzzles concentrate on one idea, pattern, and move order.
- + Manageable scope — modular repertoires are simpler to organise, update, and expand.
- + Clear boundaries — less overlap and confusion between similar lines and transpositions.
Practical tips. Name each repertoire precisely (e.g., “Caro-Kann: Advance 3…Bf5” rather than “Caro-Kann – Black”). If a branch diverges meaningfully, create a new repertoire for it. Build your overall opening system by combining focused repertoires.
Cross-repertoire insight. Cards such as Repertoire Match compare positions and lines across repertoires, helping you spot overlaps, shared structures, and transpositions.
