maxFile = 8
maxRank = 8

# 1. THE FROZEN PAWNS
# We overwrite the standard pawn (p).
# 'm(8,8)' means it can only move by leaping 8 squares forward and 8 squares over.
# Since the maximum distance on an 8x8 board is 7, it has 0 legal moves!
customPiece1 = p:m(8,8)

# 2. THE IMPOSTER BISHOPS
# We overwrite the standard bishop (b).
# 'mfW' = move forward 1 square orthogonally.
# 'cfF' = capture forward 1 square diagonally.
customPiece2 = b:mfWBcfFB

# The starting position remains completely standard!
