# THE SNAKE LEAPER
# We use 's' for our custom piece.
# It can instantly leap to any square your path would have touched.
customPiece1 = s:FNC

# THE STARTING BOARD
# I replaced White and Black's Knights (n/N) with your new Snake pieces (s/S).
# You will need to map 's' to an image in the PyChess Decorations menu!
