Problem 692. Diyan Kostadinov - Fairy (KoBul Kings, Disparate, half-neutrals)
diyan k(30.12.2015) Here is the last original for 2015. It is one my fairy problem Miniature with cyclic change of functions. I wish to all our visitors a Happy New Year 2016!







a) 1.g1S! hnBxg3=w(c6=rR) 2.rRa6 hnSxg1=w(a6=rS) =
b) 1.g1B! hnRxf3=w(c6=rS) 2.rSa5 hnBxg1=w(a5=rB) =
c) 1.g1R! hnSxh2=w(c6=rB) 2.rBa4 hnRxg1=w (a4=rR) =
In the initial position all pieces can be moved by black. Two moves later they are transformed, blocked, paralyzed or captured. Cyclic change of functions, promotions, Miniature. Total analogy in the play in all solutions. (Author)
KoBul Kings:When a piece (not a pawn) of his own side is captured, a King transforms into a Royal piece of the same type as the captured one. When the King is in the form of any Royal piece and there is a capture of one of the pawns of his own side, he becomes a normal King again.Captures are illegal if they result in self-check by the transformed King.
Disparate: when a piece has moved, the opponent's piece of same nature can not be moved on the next move.
Half-neutral piece: Piece which can exist in black, white or neutral state and changes its state by the rules:
A piece in the neutral state may be moved by Black or White, and after move it changes into black or white state respectively.
A piece in the white state may be moved only by White, and after move it changes into its neutral state.
A piece in the black state may be moved only by Black, and after move it changes into its neutral state.
Only a half-neutral pawn can promote into half-neutral figure.
Additional features of half-neutral pieces:
Castling with half-neutral King is possible with hK in white phase on e1 (White castling) and hK in black phase on e8 (Black castling). After castling the hK becomes half-neutral phase and can become mate.
A play is possible also with only one half-neutral King on the board (in white, black or neutral phase).
By the notation: “h”=half-neutral piece, states are marked with “w”(white), “b”(black) and “n”(neutral).

The black pawn in g2 can be also halfneutral pawn and the solutions are still working !

Ok, Kenneth, but the black 1st move is clearly black, so there is no need of fairy pawn to be used.
