Neutral piece: Belongs to whichever side chooses to use it. It can therefore be moved or captured by White or Black, and in Circe it is reborn according to capture. A King may not be moved onto a square controlled by a neutral piece, because of self-check.

No.1375Sébastien Luce France original – 20.02.2019

Only white King and neutral Pawn achieve black stalemate!
AUW at the end/Pin stalemate.
On move 7 neutral Pawn has to push back in b5 to capture a6. (Author)

No.1375.1Sébastien Luce France version of No.1375 – 13.03.2019

Maybe it is possible to put a black bishop in e4 instead of a pawn but it is not so nice.
I think the best solution seems to inverse black g2 pawn and neutral e2 pawn with the sol. 1.g1=S Kf2 2.Sf3…
What do you think about it Georgy and Julia ?

Grrr… it is also cook with a black bishop in e4 with 1.g1=nS Kf2 2.b1=S Snxe2 3.d4 Snxd4 4.a5 Snxc6 5.Sd2 Snxa5 6.Snac4 Snxd2 7.Bg2 Snxb3 8.Snd2 Snf1 9.Bxf1 Kxf1=
Dear Georgy Julia I think the idea of the problem is definively cook. 😕

Dear Alexandre unfortunately your proposition is also cook. The last attempt is to put a black bishop in d5 in the original position. I have to check it…

To save the idea of the problem 1375,
I propose the following version with a solution one move shorter. I invite all the composers of JF to see if there is a cook. Best to all

Stalemate scene well planned! The double jump of the neutral P comes in handy and AUW is bonus!

Very enjoyable!

Aie aie aie (in french) Georgy !

Thank you for your help.

Please Julia, replace it by another problem waiting i re work it if possible.

Inverse e2&g2 definitely will not work – black have free moves.

Be4 need more testing.

Yes you are right Georgy. To inverse e2 and g2 is cook with 1.e1=nS 😕

bPe2nPg2 and wKg3->e1?

Exchange bPe2 and nPg2. And wKg3->e1?
