The FIDE Laws of Chess give a yes in one case and refuse to say no in the other two, for two different reasons.&lt;/p&gt;&lt;p&gt;AI-generated podcast with synthetic hosts and AI-generated music. Every verdict and its stated grounds come from a recorded Arxo run; the facts, full answers and hashes are on the episode page.&lt;/p&gt;&lt;p&gt;Facts, full answers and hashes: &lt;a href="https://blog.arxo.io/podcast/02-castling/"&gt;https://blog.arxo.io/podcast/02-castling/&lt;/a&gt;&lt;/p&gt;</description>
