1. There is an illegal (shadow) puppet in the chess problem.
2. A piece is illegal if it stands in an inaccessible field, or the
author stigmatizes
a piece and classifies it as illegal (stigma on it).
3. A solution involving an illegal piece is not allowed.
The solution containing the illegal piece is a shadow
solution.
4. If the x legal piece on a) legal square is replaced by the y
illegal piece on b)
illegal square, the y illegal piece on a) legal square will
remain illegal, and b)
will be illegalx legal piece placed on square remains legal.
5. A piece becomes illegal if the square on which it stands
becomes inaccessible
due to a change in the home position.
See A), B) and C) chessproblems!

h#2 (7+8)
b) bPb7<–>wPg7
a)
The black Bishop on the a8 is a illegal piece, so the
1. b6 g8Q 2. Bxd5 Qxd5 # solution is also (shadow)
illegal, and the solution is:
1. Sd4 g8S 2. Bf6 + Sxf6 #
b)
Now the black Bishop on the h8 makes the
1. g6 b8Q 2. Bxe5 Qxe5 # line a shadow (illegal),
so the solution is:
1. Qg8 bxa8Q 2. Qxd5 Qxd5 #

h#2 (5+7)
b) bBg8<–>bBh8
a)
Because h8bB is a shadow-piece (illegal-piece),
there can be no solution (shadow-solution):
The g8 bB is legal-piece, so the solution is:
1.Ke4 f8=Q 2.Bd5 Qxf4#
b)
after exchange, there can be no solution (shadow-solution):
The h8 bB is legal-piece, so the solution is:
1.g5 a8=Q 2.Bd4 Qf3#
