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.
