h#2,5 Haan Chess Transmuted Kings

: a square left by a piece becomes a hole and cannot be crossed
: a king in check catches the march of the piece that puts it in check until it parries the check (or becomes mate)

h#2,5 Haan Transmuted Kings(2+1)
2 solutions

Solution

{

In Haan Chess (located near Solingen, towards Düsseldorf), a square evacuated by any unit becomes a hole, which can neither be occupied nor crossed.
A "hole" is represented here by a black pawn.
Visually, this looks like "Sentinel" chess, but only with a defecation of black pawns !

} 1...f7-f8=R[+bPf7] 2.Kd4-c5[+bPd4] Rf8-a8[+bPf8] 3.Kc5-b6[+bPc5] d7-d8=B[+bPd7]# ! {
(bK, transmuted into B, cannot occupy or cross c5. Another detail, the a5 square is only controlled by the rook in case of Ka5 ! )

} 1...d7-d8=Q[+bPd7] 2.Kd4-e4[+bPd4] Qd8-e7[+bPd8] + 3.Ke4-h7[+bPe4] f7-f8=S[+bPf7]# ! {
(bK is transmuted to N, but not to Q because of the f7 hole which prevents it from reaching h7
. Here we have an AUW with minimal material.)}

h#2 All-in-Chess

All-in-Chess One can play one's own pieces or the opponent's pieces,
provided that one does not return immediately, which would cancel a move made
