Thank You,

but the last analysis is _wrong_ (german: falsch), sorry:

1...Ka8 2.Ka4 Ka7 3.Ka5 Kb7 4.Kb5 Kc7 5.Ka6 Kd8 6.Kb7 Kd7 7.Kb6 Ke8 8.Kc7 Ke7
9.Kc6 Kd8 10.Kxd6+- and white win!! Line

In the variation black was after 2...Ka7????? losing! Right is here only 2. Kb8!
with draw.

Regards,
Eduard
