My idea of the tactics involved being to keep the 'hole' ''away'' from the vicinity of any defensive formation you may have, lest your opponent gets to move your pieces out of formation and then procedes to further reshuffle your end of the board with the &amp;quot;portable hole&amp;quot; in ways are also actively disruptive to your placement. Conversely: make them ''think'' they're doing that, but actually letting them bring your pieces out, en mass, in a more valuable offensive arrangement. ;) [[Special:Contributions/82.132.245.43|82.132.245.43]] 22:33, 10 September 2025 (UTC)&lt;/ins&gt;&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;

Or call it &amp;quot;(from)›&amp;quot;, perhaps. Piece-moving notation often omits details that can be infered, so the sole/only queen that can land on &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;d4 &lt;/ins&gt;just needs &amp;quot;Qd4&amp;quot;.
