No.591 by Dmitri Turevski – An interesting thematic with combination of two quite different types of exotic pieces! (JV)


Definitions:

Hurdle-Colour-Changing Equihopper: Like a normal Equihopper but it changes the color of the piece it jumps over.

Equihopper: Moves along any line over another unit of either color to a square situated such that the hurdle stands at the mid-point between the Equihopper’s departure and arrival squares.

Chameleon: On completing a move, a Chameleon (from classical standard type) changes into another piece, in the sequence Q-S-B-R-Q… Promotion may be to a chameleon at any stage in the cycle.

Nice! Popeye 4.69 tells me that hEQ is an offending item?!
Would the problem be correct after moving bPf5 to e6 and whEQh3 to f5? The tries would be 2…cBc3+/cBg2+?

Nikola’s suggestion leads to a cook:

stipulation h#2
pieces
white Ka6
white HurdleColourChanging EQf5d6
black Pf7a7e6 Ke8
black Chameleon Bd4f3

1.cBf3-a8=cR hEQd6-d2[d4=w] 2.0-0-0 cBd4-c5=cR #
1.cBf3-d5=cR hEQd6*d4[d5=w] 2.f7-f6 cRd5-d7=cQ #
1.cBd4-h8=cR hEQf5-f1[f3=w] 2.0-0 cBf3-g4=cR #

I am not sure it is a good proposal, but it is possible to get a correct position with the Nikola’s idea by putting black hccEq on e6 and black pawn on a4.

Thanks Geoff, at least now I’ve learned how to make the popeye input.
