Stalemate??? Do you want to say that in your solution mate has to capture
almost all black pawns, even the ones an a/b-line?
Then your way of solution must really be completely different than the one
for the original #13, and I´ve absolutely no idea how it might look like.
OTOH if the black king captures h3/g4-pawns, how should he be mated then -
at least in ´only´ 22 moves?

Would be interesting to see your solution ...

Franz.
