Three dimensional chess game

Abstract

A method for playing a two-level chess game on apparatus comprising, upper and lower spaced apart congruent traditional chess boards with traditional sets of chessmen positioned for chess play respectively on the first two rows of opposing sides of the lower chess board, where the method includes the steps of transcending and descending a playing piece from a square on one board to a congruent transfer square on the other board and optionally moving the transferred playing piece from the transfer square to a move ending square whose maximum distance from the transfer square is a selected fraction of the number of squares the playing piece would be authorized to move without having been transcended or descended, not counting the transfer square.

1 . A method for playing a two-level chess game on apparatus comprising,
 upper and lower spaced apart congruent chess boards each having a grid of eight by eight alternating contrasting squares in files and ranks, with each square defining a playing piece position,   a first force and a second force of chess playing pieces, each including a king, a queen, two bishops, two knights, two rooks and eight pawns, and adapted to be positioned for chess play respectively on the first two rows of opposing sides of the lower chess board, where the method includes the steps of,   transcending and descending a playing piece from a square on one board to a congruent transfer square on the other board and optionally moving the transferred playing piece from the transfer square to a move ending square whose maximum distance from the transfer square is a selected fraction of the number of squares the playing piece would be authorized to move without having been transcended or descended, not counting the transfer square.   
   
   
       2 . The method of  claim 1  where the selected fraction is one half. 
   
   
       3 . The method of  claim 1  where the transcending and descending playing piece possesses its full movement authority on moves subsequent to a transcending or descending move of the playing piece. 
   
   
       4 . The method of  claim 1  where, except for the Knight, the transcending or descending playing piece of the first force captures a playing piece of the second force which is positioned on the transfer square. 
   
   
       5 . The method of  claim 1  where the transcending or descending playing piece of the first force captures a playing piece of the second force which is positioned on the move ending square. 
   
   
       6 . The method of  claim 1  where a transcending or descending playing piece of the first force freely passes over or under other playing pieces of the first force that are positioned on the board from which the transcending or descending piece originates. 
   
   
       7 . The method of  claim 1  where, on its first move, a transcending pawn of the first force moves one file square from the transfer square or captures a playing piece of the second force on the transfer square or on one diagonally forward square from the transfer square. 
   
   
       8 . The method of  claim 1  where the King is limited on a transcending or descending move to the transfer square. 
   
   
       9 . The method of  claim 1  where a transcending or descending Knight is limited to one diagonal square from the transfer square. 
   
   
       10 . The method of  claim 1  where playing pieces of the first force put the King of the second force in check and checkmate from the same board on which the King is positioned or from the board on which the King is not positioned.
