+  | Giving check is forbidden, unless it is a checkmate.
+
+p.
+  Neither player is allowed to give a check, with the exception of checkmate.
+  Thus, the king is much more powerful than in orthodox chess: as long as
+  he can (potentially) escape, he doesn't fear attacks.
+  So the king can be used to defend pieces in an unusual way.
+
+p.
+  On the following diagram, 1.Qxa6 threatens 2.Bb6
+  with a mate to follow by Qxa7.
+  The black rook cannot take because it would check the white king.

+p.
+  1.Qf7# is checkmate on the left diagram, because if the king takes
+  then the rook on h8 gives check but not checkmate.
+  However, on the right diagram 1.Qf7+ runs into 1...Kxf7#, which is now
+  a legal move because the white king is checkmated.
