Editorial responsibility
Material is published by the ChessGrade team. Pages identify the responsible organization and review date. Our purpose is educational; we do not claim individual professional authority or promise competitive results.
Examples and review
Positions are selected for teaching value. FEN, side to move, and solutions are checked on a board and, where useful, with an engine. Explanations distinguish verifiable facts such as legality and mate from pedagogical recommendations.
AI assistance
AI may assist drafting, translation, or organization, but it is neither listed as an author nor treated as a primary source. Publication requires checks for language, chess coherence, moves, attribution, and links. Unreviewed automated pages should not be published.
Corrections
Readers can report issues at [email protected]. Material corrections update the page date; purely stylistic edits may not. Engine-based claims disclose that basis, while opinion and teaching guidance are labeled by context.
Updates
Foundational guides are reviewed when the product, source, or explanation changes. Legal pages receive priority when data handling or providers change. Dates are not refreshed without a substantive change.
How we separate fact, analysis, and opinion
Our texts distinguish three kinds of claim. Verifiable facts — whether a move is legal, whether a sequence forces mate, what a position's FEN is — are checked on the board and, where needed, with the engine. Engine-based analysis is presented as such, disclosing that its basis is a program's calculation. Pedagogical guidance — the suggested study order, the emphasis on a theme — is the team's reasoned opinion, not absolute truth. Making that boundary explicit helps the reader know how much weight to give each sentence and lets them correct us when they disagree.
