To play this variant of chess, it is enough to connect two chessboards together and place both sets of pieces.
The game is played on a 8x16 chessboard with each player in control of two complete armies.
The normal chess rules apply, except that each of the kings can castle only on their side of the board, occupying the square on which the knights are standing. So White's left king can only castle to the left, moving either to square b1 or to square e1.
A player wins by checkmating either one of the opposing kings. If two of the opponent's kings are in check at the same time and it is impossible to eliminate this check for both kings (at least one is still in check), then this situation is considered as a checkmate.
The idea is not new. It echoes with Parton's Tweedle Chess and a chess variant invented by Julian S. Grant Hayward in 1916 (Double Chess on a 12x16 board).
