Wikibooks opening commentary
Knight’s Eye may supply material from Chess Opening Theory on Wikibooks to its AI assistant. The assistant may use, excerpt, summarize or adapt that material alongside game records and engine analysis. Supplying a source does not mean every answer uses its text.
Wikibooks text is contributed by Wikibooks authors and is generally available under the Creative Commons Attribution-ShareAlike 4.0 International license, unless otherwise noted. Each source page’s history identifies its contributors. See Wikibooks’ copyright and reuse information.
Reused excerpts retain their source license. Where an answer adapts protected Wikibooks text, that adapted material, including Knight’s Eye’s contributions to the adaptation to the extent copyright applies, is offered under CC BY-SA 4.0. AI summarization, rewording and combination with analysis may change the original. This notice does not apply that license to unrelated application code or independent content.
Wikibooks contributors and the Wikimedia Foundation do not endorse Knight’s Eye or its AI answers. Source material and AI explanations may contain errors. The source license includes a disclaimer of warranties.
