+  | All pieces can be captured en passant, by any piece.
+
+p More precisely:
+ul
+  li.
+    A piece making a multistep move can be captured by an opponent's piece
+    guarding a square on its way; this capture is only possible right after
+    the move (same condition as for en passant pawns captures).
+  li.
+    Even if the capturer gets captured en passant on next turn,
+    the initial captured piece does not return to the board.
+
+p This is a generalisation of the pawn en passant capture, which is still possible.
+
+h3 Special moves
+
+ul
+  li.
+    Knights become knightriders, which may make multi knight-steps in the same direction.
+    For example in the standard initial position, the knightrider on g1
+    can go to e5 or capture d7 in addition to the knight moves (see diagram below).
+  li The king can capture a piece en passant by making a knight move.
