Well, kibitzer does have the solution…it is not completely solved after Bf3. You see black can only allow one free move for white. After the 2nd free move, the a or b pawn is queen (and you see the back rank problem in black’s side of the board).
After Bf3, if hxg2, then Qb1 mates, so Kh7 is forced. … Kh7 Bxg2+ Bxg2 Qxh4+ Bh3 Qf4+ Kh8 Qf2 axb7 Qg1#
Nf2+ Nxf2
Qxf2 Qg2
Bf3 and black wins
1 Nf2+ Nxf2
2 Qxf2 Qh2
3 Bf3+
Nf2+ Nf2
Qf2 and white’s position falls apart
Mark
1. …Qxe4+
Nf2+ is the right move I think. Qf2 and Bf3 next. Or is there a better solution?
nxf2 kg2
nxq pxp(b7)
then mate in several moves

I don’t get any clue because of the typos… when does “hxg2” come?
After 1..Nf2+ 2.Kh2 has to be considered because white has a new queen coming and it might be tricky to find a forcing win for black.
Yeah toughest defense for white is Kh2. It gets tricky after that.
