paul: Since the wB couldnt leave c1, the captured piece on b6 is the promoted wPh2. If last black move was f7-f5, then h-Pawn captured four pieces to promote on d8, among which bRh8, impossible. Thus, the h-Pawn could only have been promoted from f7 and therefore d7-d5 remains as the last move. (2011-07-02)

R: 1. ... h2xDg1=K, dann 1. Ka1 Db6+ 2. Kba2 Db2#

Arnold Beine: Die erste Lösung geht nicht, weil am Ende der sKa3 noch das Fluchtfeld b4 hat.
Korrekturvorschlag: +sBb4 (dann geht nur die 1. Lösung) und als Zwilling "b) -sBb4" (dann geht nur die 2. Lösung) (2022-08-28)
