#4 All-in-chess Growing men(8+3)
All-in chess "Complete" or "all-in" chess. One may play one's own pieces or the opponent's pieces, provided that one does not return immediately, which would cancel a move made. For example in Kf1, Pa7 & h2 / Kh1, you mate in 2 by 1 a8B+! (1 a8Q+? Qa6) Kxh2 2 Kh1!!# (this is not the same position), which would be illegal without the Ph2. Furthermore, in this problem we are in growing men where a unit can never play a move shorter than the last move it made.

1.a3-a4 ! {This proves that the a6 pawn is enlarged,
Black can never reply a6-a7 giving the escape b7. On the other hand,
the b6-pawn is not enlarged, it can come from b2, while the pa6 would come
from c2, d2 or e2.}
a4-a5 {the best black move. 1...Ka8-b7 is illegal because of a6 pawn. And 1...Ka7-b8?! allows 2

{this move is possible because the position has been changed: minus Nh8}
6.h7-h8=B {The fact of playing a move of length 1 proves
that this pawn is not enlarged (so it comes from h2), so it is the h6 pawn that
is, which cannot subsequently play h6-h7.
- 6.h8=R# ? Rc8 7 Kf8 Rc3 8 Ke7 Rh3 gives nothing.
- 6. h8=N? Nxf7 and the knight flies into the wild.
- 6. Kf8 ? h8=N!}

"push" the white king where it wants to go, as Black has no other moves.}

🨑c8: Faro🨒g6: Loco
, invented by Mr. Rittirsch in Andernach in 2016, reverse the rules of Chinese Chess:
a piece plays "normally" when it captures, but needs a sautoir to play a move which is not a capture.
The Leo becomes a Senõra, the Pao a Faro and the Vao a Loco.
It is Faro on c8 and a Loco on g6.
The Señora is absent.
As well as the equivalent of Mao & Moa, the Saltador, who plays like a Knight,
except that he cannot capture if the two intermediate squares are occupied, and that he cannot play a non-take if the two intermediate squares are empty.
For example, if the Ne7 were a Saltador, it could only play a single move (but could capture a white f5 pawn).
However, if it were moved to a5, then it could play b7, c6 & c4 but could not capture b3.

I met Jean Oudot in 1962 or 1963, but I confess to being ignorant of this theme.
