Problem 613 (613.1): Krassimir Gandev - Fairy (Mirror Circe, Locust, neutral Pawn)

krassimir.gandev(13.10.2015) Wonderful fairy problem by Krassimir Gandev with double mirror stalemate after 9 Locust promotions.

The problem was found cooked and the author makes version 613.1 which is with Bishops instead of Knights on the initial position.

Mirror Circe: Like Circe, but the rebirth square of a piece is the square occupied at the beginning of an orthodox game by a piece of the same kind and of the other side. Related to the square they occupied before the rebirth:Rooks, Bishops and Knights are reborn on the square of the same color;Pawns (including fairy Pawns) are reborn on the same file; other fairy pieces are reborn on the same file and on the promotion rank of the other side.

Locust: a piece which moves only to capture. It lands on the same squares as a grasshopper, but the arrival square must be empty, because the locust captures its hurdle.

Neutral piece: A unit with this characteristic may be regarded as of either colour by the side whose turn it is to play. Neutral pawns promote to neutral pieces.

I think a mirror stalemate needs K in non-edge square and all squares around him to be empty.

I don't know is there such an definition, but I called it "mirror double stalemate" because visually both Kings/Knights stalemate positions looks mirrored.
And Seetharaman, this is not because of the used condition (Mirror Circe), but because the final stalemate position where both Kings positions are visually mirrored.

I understood Diyan. My comment was just in fun! You are right the king/knight positions are indeed a mirror reflection!

Popeye shows it's cooked, eg:

7... Sa5*b3[+nPb2] 8.nPb2-b1=nL h7-h8=L 9.Lh3*b3-a3 + Ka4*a3[+bLa8] ==
