Les échecs duodécimaux
For the Ancients, 12 was a perfect number. Much more than 10, since it can be divided by 2, 3 and 4. This game is simply a chess variant on a 12 x 12 board with 12 different pieces. The balance does not stop here, just consider this:
There are the 6 orthochess pieces plus 6 new ones mostly borrowed from most famous chess variations, historic and regional:
Pawns are the soul of Chess, Philidor used to say. In order to accommodate the large size of the board, it was necessary to increase their power as well.
I had it in my mind for several months, I should say years ! The key to set it up definitely has been the wonderful Zillions-of-games program. Without such a tool, it would have been impossible for me to try all the so many configurations I have tested. I came to this implementation at the end of April 1999. The rules have been slightly modified in April 2008 (with Prince's promotion and 2 steps castling instead of 3).
The board is a 12 x 12 checkered squares with a white one at the right end of each player. For convenience, it can be divided into 16 sub-square showing halves and quarters of this large battlefield: 12 is really a nice number for a board.
There are 36 pieces per side: 1 King, 1 Queen, 1 Gryphon, 1 Lion, 2 Princes, 2 Bishops, 2 Knights, 2 Rooks, 2 Elephants, 2 Cannons, 2 Camels and 18 Pawns.
The white King is placed on the center of the second row on a black square, the black King beeing on a white square. The Queen is placed beside of the King. The Lion and the Gryphon are on the center of the first row, the Lion just behind the King.
Moves And Captures
Castling: the King may `castle` with the Rook if neither the Rook nor King has moved yet and there is nothing in between them. In castling the King slides 2 squares to the Rook and the Rook leaps to the far side of the King. You may not castle out of or through check, or if the King or Rook involved has previously moved.
End Of Game: Victory is obtained when the opposite King is checkmated. All other types of endgame (pat, perpetual check,...) are classic.
Zillions gives these average values, normalized to 5 for the Rook:
Pawn: 0.8, Camel: 2.1, Elephant: 2.3, Knight: 2.4,

"Les pions sont l'âme des échecs" disait Philidor. Ici, étant donné la grande taille de l'échiquier, les pouvoirs du Pion ont été augmentés.
