The WikiBooks card displays community-written opening theory from Wikibooks.org for the current position on the board. Each entry provides strategic explanations, typical plans, and historical context for the opening, helping you understand the ideas behind the moves rather than just memorizing variations. You can read the theory directly within the card to understand the positional goals and common continuations for your current position.
This feature helps you:
- + Understand the strategic ideas and plans behind opening positions
- + Learn opening theory with context and explanations, not just moves
- + Access free, open-source chess theory curated by the chess community
Note: WikiBooks content is sourced from the open-source Wikibooks.org Chess Opening Theory project. Not all positions have written theory available, but coverage is extensive for popular openings and main lines.
