No.585 by Neal Turner – Three different mates by a black Royal Grasshopper in s#2 with detailed author’s comments! (JV)


Definitions:

SAT: A king is in check if any of its flight squares are unguarded by opposing pieces.

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.

Royal piece: Piece that executes a function of the King on the board.

    I suppose with the Animated Diagrams we have to have just the actual solution.
    But sometimes we need to show more to make the idea clear:
    1.Sc4! (> 2.g3+ rGf2#)
    1…e6 (> 2.g3+ rGf2+ 3.Se3+) 2.Se3+! rGd6#
    1…Ga7 (> 2.g3+ rGf2+ 3.Sd6+) 2.Sd6+! rGc6#
    Maybe it’s a more interesting challenge for composers than for solvers.

    Like Antikings, SAT is itself a complex condition for those new to it to grasp. Thanks to Neal Turner for the detailed explanation making me under this beautiful problem. Great !
