  a) 1.Ke6 d8Q 2.Qf5 Qe7#

 b)=# a) wQ=wP  1.Bd7 e8S 2.Rd6 Sxc7#

c)=# b) wS=wP  1.Kd5 c8B 2.Kc6 Bb7#

   d)=# c) wB=wP  1.Sa8 bxa8R 2.Qd5 Ra6#

Nikola gives an alternative method of exhibiting the solution (which will show the Cinderalla effect clearly !)

1. Ke6 d8Q 2.Qf5 Qe7# (wQ=wP) 3.Bd7 e8S 4.Rd6 Sxc7# (wS=wP) 5.Kd5 c8B 6.Kc6 Bb7# (wB=wP) 7.Sa8 bxa8R 8.Qd5 Ra6#
