The solutionist must find and prove the nature of the handicap. Economy in the slogan and «conditions» (as in the material!).
Preliminary analysis:A bit like a retrograde analysis,the solutionist easily show lines

1.Bd8 Rh7 2.Ke2 Kç3 3.B×a5+ Kb2 -+
1.a4 Kç3 -+
1.Kd1 a4 -+

and deduced that the only move to obtain Draw is 000!! with Rock a1(Handicap Game),then gives the complete solution.

1.Nb3+! Libere a1 so allows the next white move.
