+  | Checkmating the queen wins too. A queen cannot go or stay under check.
+
+p Just as the king, the queen can be checked and mated. This means that
+ul
+  li It is not allowed to make a move such that the queen can be captured.
+  li.
+    When your queen is attacked, you must play a move such that the queen
+    is no longer attacked.
+  li If it's impossible, then you lose.
+
+p.
+  Since the king remains royal, this allows a new way to win: check both
+  royal pieces at the same time, like on the following diagrams.

+  You can castle with the queen or the king and any of the two rooks,
+  under the same conditions as orthodox castling.
+  Here is the resulting position after two white small castles and
+  one black large castle with the queen:
