    nicely motivated under-promotions

    A version suggested by Jacques saves a pawn and has a neat tempo move for black. But I prefer the black rook moves of my version.

    Thanks Julia for accepting our new version. Two sets of underpromotions make the problem complete!

    The bishop passes through f4 to reach d4
