prize13-3, Exercise 3: Extending the script

Model answer (check the details):

    pieces = {
        "shah":   ("king",   "one square in any direction"),
        "firzan": ("queen",  "one square diagonally"),
        "fil":    ("bishop", "two squares diagonally, leaping"),
        "faras":  ("knight", "as the modern knight"),
        "rukh":   ("rook",   "as the modern rook"),
        "baidaq": ("pawn",   "one square forward; captures diagonally"),
    }

    for old, (new, move) in pieces.items():
        print(f"{old:8} -> {new:7} {move}")

For the queen the output line is:

    firzan   -> queen   one square diagonally

This shows how much weaker the shatranj counsellor was than the modern queen, which moves any distance in any direction.

Care: the shatranj moves are the usual account and some details are debated.
