Hi guys,

Today I spent a lot of time improving and restructuring the Endgame Lessons section of my chess platform. One of the biggest changes was reorganizing the codebase to make it cleaner, more modular, and easier to maintain as the project continues to grow. I reworked how lesson data is stored so that each lesson now has its own clearly defined position, learning objective, explanation, highlighted instructional squares, practical application, and reflection question. This makes adding new lessons much easier in the future and keeps the code organized instead of having information scattered throughout the file. I also upgraded the lesson content itself by replacing shorter descriptions with much more detailed educational explanations that focus on the reasoning behind each concept, helping users understand not only what to do but why they should do it. The board visualization was improved as well, with important squares now highlighted directly on the board to make key ideas easier to identify. I refined the page layout to create a more structured learning experience, separating objectives, explanations, applications, and review questions into distinct sections that are easier to follow. In addition, I cleaned up variable naming, improved readability, reduced repetitive code, and made the overall architecture more scalable so future endgame topics can be added with minimal changes. The result is a much more professional and educational system that feels less like a collection of chess positions and more like a dedicated endgame learning course built directly into the platform. This update lays a stronger foundation for future features such as interactive lessons, guided practice positions, move validation, progress tracking, and advanced endgame training modules.
