Black play only to double check

    Indeed a rare condition! Normally when a condition like this is imposed on Black, it usually means:
    a) Black obeys the condition, if possible, else he plays normally OR
    b) Black obeys the condition, if possible, else he’s in stalemate

    But here, there’s a third option:
    c) Black obeys the condition, if possible, else he skips a move!

    But well used by the composers to show a double Zabunov and 2 rundlaufs.

      The genre could be a sub-variant of: Black must check if able or does not play at all. In german, Schwarzschäche.

    Ingenious use of the condition to create new batteries! Bravo.

  3. Nicolas Dupontdupont says:

    One can see this problem as mainly a series one, where black must break the white series under particular circumstances.

    In e.g. parry series, this particular circumstance is when black is in-check, when black can check in schwarzschache, and when black can double-check in this problem.

    There are other variations on the same principle, such as “black play only to capture” (winchloe).
