Hello,
I have thought about a new chess variant: "DOUBLE KING CHESS". It is played on a board 12x10.The pieces (letter from a to j) are so collocated:Rook, Horse, Bishop, chancellor, Queen, King, Amazon, Marshall, Big King (a Bigger King that can move even two squares in every direction with possible jump), Bishop, Horse, Rook. No en passant rule. Castling is allowed like standard chess. Big King can not be checkmated. If Big King reach the last row the colour that obtain it win the game. A pawn can promote even on 8t row.
Thanks in advance for attention.
Cheers.
