   2   | Giving check is forbidden, unless it is a checkmate.

   5   Neither player is allowed to give a check, with the exception of checkmate.
   6   Thus, the king is much more powerful than in orthodox chess: as long as
   7   he can (potentially) escape, he doesn't fear attacks.
   8   So the king can be used to defend pieces in an unusual way.

  11   On the following diagram, 1.Qxa6 threatens 2.Bb6
  12   with a mate to follow by Qxa7.
  13   The black rook cannot take because it would check the white king.

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