A brilliant puzzle from a game.
Sort:
Only computer can solve this puzzle.
I will analyze it.
Maximum can't solve this puzzle.
Computers cannot really solve it unless run at very high depth XD
Stockfish (depth 18) says this is draw.
Stockfish cannot see it unless it reached depth 48+.

Qb3+ Kh8 Qc3+ Kg8 Qc4+ Kh8 Qd4+ Kg8 Qd5+ Kh8 Be5+ Nxe5 Qxe5+ Kg8 Qd5+ Kh8 Qd4+ Kg8 Qc4+ Kh8 Qc3+ Kg8 Qb3+ Kh8 Qb2+ Kg8 Qxa2+ Kh8 Qb2+ Kg8 Qb3+ Kh8 Qc3+ Kg8 Qc4+ Kh8 Qd4+ Kg8 Qxd7 Ng5 Qd5+ Kh8 Qd4+ Kg8 Qc4+ Kh8 Qc3+ Kg8 Qb3+ Kh8 Qb2+ Kg8 Qa2+ Kh8 Qxh2+ Kg8 Qa2+ Kh8 Qb2+ Kg8 Qb3+ Kh8 Qc3+ Kg8 Qc4+ Kh8 Qd4+ Kg8 Qd5+ Kh8 Qe5+ Kg8 Kxg5
now Qg7+ Qxg7+ Kxg7 Kxf4 wins easily
fxg3 Kg6 g2 Qd5+ Kh8 Qd4+ Kg8 Qc4+ Kh8 Qc3+ Kg8 Qb3+ Kh8 Qh3+ mates
f3 (this line is the same for e3 btw) Kg6 f2 Qd5+ Kh8 Qd4+ Kg8 Qd7 mates
Qb4 (or Qa3) Qe6+ Kh7 Qf7+ Kh8 Qf6+ and next move bishop check leads to mate
honestly I probably mistyped something, but the idea is pretty obvious
