No.759 by Illo Krampis – Light problem on the theme of Superproblem’s TT-131 (сyclic shift of guards). I’m happy to meet and introduce to you a new Latvian fairy composer! (JV)


Definitions:

Grasshopper (G): Moves along Q-lines over another unit of either color to the square immediately beyond that unit. A capture may be made on arrival, but the hurdle is not affected.

Berolina-Pawn (BP): Walk and capture are swapped relative to the orthodox Pawn. The Berolina-Pawn moves without capturing diagonally (possibly two squares if it is on the second row of its side) and captures vertically.

  1. Kjell Widlert says:

    The neat line of grasshoppers on the first row enhances the effect of the cyclic shift. The untidy twinning is the weak spot of the problem.

  2. Mike Neumeier says:

    Solved A quickly, then because I mistakenly had a normal pawn at h6, many minutes were contheme there Once I realized it was BP there and BPg5 possible, line B fell quickly, as did the last two. It is funny in a way, this battering ram of four grasshoppers not used as a press against Black. Those grasshoppers are content to hop away on other excursions! Good four-way theme.

    Congrats to Illo Krampis for his successes (1st Prize, Special Prize) in SuperProblem TT-131 and thanks for another nice contribution to the theme! Could this be done without technical fairy pawns?
    The shift of guards is as follows:

    Ge1 Gf1 Gg1 Gh1
    a)
    b2 a1 c1 b1
    b) a1 c1 b1 b2
    c) c1 b1 b2 a1
    d) b1 b2 a1 c1

    • Mike Neumeier says:

      Perhaps it can be done without BP’s, but where to start? cBP change to P and put a G at c1? Changing the other fence (bBP) looks more difficult…we already are using a light-square B on d1. BP’s in this problem used effectively. Looks tough.

      • Mike Neumeier says:

        Although, I wonder what might be made out of G’s at, say, a1, a2, a3, a4.

      • Manfred Rittirsch says:

        It’s not the cage for the bK that is the problem here, I verified that this could be handled with orthodox pieces after rotation. The problem is the piece on h6 in a) and b), which would cause duals in b) if it was a bishop.

        • Mike Neumeier says:

          Manfred, adding black pawn h7 removes dual in b). Thrown out is Bg5. What is your nest without BP’s?

          • Mike Neumeier says:

            This b) gives the fG the mating move after key Bf4, but the gG’s mate is now lost. Must keep the cyclic. Three cheers for Berolina pawns!

  4. Mike Neumeier says:

    Cancel add bPh7, instead add bPe6. gG’s mate is retained…thrown out is Bf4 dual.
