Cannon Pawn Orda

See: https://blog.silverview.buzz/variants/orda The Horde against the Kingdom. The Horde features Cannon Pawns instead of regular pawns. Cannon Pawns move as a king OR they can hop over any adjacent piece to either land on a vacant square behind it (move) or if that landing square is occupied by an enemy piece, the cannon pawn will capture it by displacement. The Cannon Pawns start on rank 7 (not 6). All else is as in Orda, including promotions (both pawn types can promote) and castling allowed to the FIDE Chess army. Win by Checkmate or Campmate as in Orda.
