Serial selfmate in 13. Anti-Circe.

"Serial selfmate in 13" means white makes 13 consecutive moves such that in the final position black is forced to mate in 1.

Series problems are often very easy to solve, given the current trend of promotion themes, especially AUW (Allumwandlung, or promoting one piece of each type).

1.e7 2.e8=R 3.Rd8 4.R*d6[Ra1]
Important to make the R capture on a dark square so he ends up on a1, not h1.
5.d6 6.d7 7.d8=N 8.Nxc6[Nb1]
And the N must capture on a light square to reach b1.
9.c6 10.c7 11.c8=Q 12.Qf5 13.f8=B+
The only way to nullify the check is the Anti-Circe option of occupying the rebirth square of the attacker, so that he loses his ability to capture (rebirth of the capturing piece is mandatory, or else the capture is illegal).
