Here's your challenge:

[D]8/7p/5p2/6k1/8/6P1/5PPK/8 w - - ; bm Kh1;

It's not practical to ask programs to provide solutions in the form of complete
variations and subvariations. It's more practical to add to the 6 original
positions positions from critical variations and ask the program to make the
correct choice. This will enable to present this contest as a regular search for
key move suite.
