It seems to me that if the Valladao task really does incorporate "moves
special only to chess" that an underpromotion would be required; in a game
like draughts, promotion is possible and probably other games too. Are there
other games that have UNDER-promotions?
But I am not to be regarded as an expert in the least. I am asking more than
stating.
