-  Kings have no royal status. There are no en-passant captures, and no castle.
-  "Zen" captures are possible too: if a piece A attacks a piece B
-  (in the usual way), then B can capture A.
+  Kings have no royal status, and move like orthodox queens.
+  Knights become knightriders: they can make any number of knight steps in a
+  direction. There are no en-passant captures, and no castle.
