    White needs to promote a pawn to add a third attacker. Black has several ways of playing out his pawn tempos. White must choose his promotion carefully to provide a timely unpin once the pawn tempos run out.

    I'd like to know the composer's name, publication, and year if you have them.

    I think I saw this problem on one of Krabbe's dutch language columns:

    Unfortunately columns 1-309 are now gone. I don't know if I saw it in one of the surviving ones or not. Try asking Krabbe:

    Just found in my notebooks:

    The problem is by J. Pedersen, 1952.

    I don't know the place of publication.
