Anti-Circe Cheylan: When a piece captures (including King), it must come back to its rebirth square. If this square is occupied, the capture is forbidden. A Pawn capturing on its promotion rank promotes before it is reborn. The captures on the rebirth square are forbidden.
Isardam: Any move, including capture of the King, is Isardam illegal if a Madrasi-type paralysis would result from it. (Madrasi: Units, other than Kings, are paralysed when they attack each other. Paralysed units cannot move, capture or give check, their only power being that of causing paralysis.)
Royal piece: Piece that executes a function of the King on the board.
Double Grasshopper (DG): Makes a Grasshopper move without capturing, then a 2nd Grasshopper move. (Grasshopper: 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.)
No.1274Peter Harris South Africa original – 18.02.2018
Klaus Wenda’s 75th birthday tourney featured the DoubleGrasshopper. The Awards have just been published in the latest feenschach f-225. The judges were Klaus and Hans Gruber. Reading the judgment prompted me to make this problem. (Author)
No, Shankar, actually I found a set play in 3 moves.

Sorry, Paul!
You’re right. The move numbering confused me.
So, it’s actually a hs#3.5 with 2 solutions and 1 set play: 0.0.1.1.1.1.1.1 + 0.2.1.1.1.1.1.1
Maybe the numbering in such cases should be like:
2.Rf7+ rDGg8 3.b6 rDGa6 4.Rc7+ Rxb6(Rb6→h8)#
1…Rb3 2.Re7 rDGf8 3.b6 rDGa6 4.Rc7+ Rxb6
(Rb6→h8)#
1…Rf2+ 2.rDGg1 Rf8 3.Rc7 rDGd8 4.Rc8+ Rf1#
This set play could also work as a 3rd solution, if “stationary moves” are allowed!:
1…rDGb1-b1! 2.Rf7+ rDGg8 3.b6 rDGa6 4.Rc7+ Rxb6(Rb6→h8)#
Maybe Peter *did* notice this set play but decided not to indicate it.

Set play is virtually the same as the first solution, so it doesn’t add a thing.
Paul Raican reports an accurate(and I assume unique!) hs#4 solution:

So, the stipulation can be changed to hs#4**.
