Sorry, I do not know or remember the solution to this problem....
Maybe someone here can post it....
c3+/ Na4+/ c4+/ Bf3/ (now black K is trapped in a6)
wK goes to g2/ wK captures promotion at h1/ wK goes to c8/ wBishop captures all the pawns that will move in the diagonal h1-a8/ Bb7#
Those are 22 moves, on the meantime, black can only shuffle the bishop around.
