Problem 329: Janos Mikitovics - fairy (Swapping Kings, Anti Einstein Chess, Locust)

mikitovics(31.01.2014) Help-selfmate with dedication and good contrast twin by Janos Mikitovics from Hungary.





329.1

    Swapping Kings: When the side on-move checks the opposite King, the Kings change places. This is known as the “swap”. A swap is mandatory. The legality of any checking move is evaluated after the swap, except in certain cases involving castling. Castling out-of–check is illegal (wKe1 wRh1 bKe8 bBa5, 1.0-0??). Castling through check is illegal (wKe1 wRh1 bKf8 bBa5, 1.0-0??). Castling into-check is legal (WKe1 WRh1 BKf8 BBa7, 1.0-0!) A King swapped back to its game-array square is considered “reborn” and is eligible to castle.

    Anti Einstein chess: every time a piece moves (without capturing), it "loses energy" and transforms itself ("is demoted") into a smaller unit, one step down the ladder from Queen to Rook to Bishop to Knight to Pawn. Kings do not transform. A non-capturing Pawn-move does not lead to any transformation. You can also have pawns on the 1st-rank (after a non-capturing Knight move): these pawns can make a single, double or triple step forward. After a double or triple step, they can be captured en-passant by an enemy pawn on the 3rd or 4th rank. After a triple step, en-passant capture can take place on two different squares!

    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.

According the definition of Einstein chess the promotions are not allowed, but here we see promotion of Locust. Is the rule do not exist for promotion of fairy piece?

Sorry Janos. It was look to me as Einstein. I will change it when I come back at home tonight.
I saw that Popeye do not solve Einstein with fairy pieces on the board, but solve Anti-Einstein. WinChloe solve Einstein with fairy pieces, but when a Pawn moves without capturing it become that kind fairy piece.

Ok Diyan, thanks!
It seems, the condition may not be Einstein, because the fairy pieces may not be reborn/captures. If the cond. is Anti Einstein, the pieces (orthodox and fairies) doesn't change when it captures. I think, the WinChloe is here faulty...!?
