Black to move. Mate in one.
LET'S SEE SOME PUZZLES!!!

Qxd1+
1.Qxd1+ (in #47) does not result in checkmate. You need to provide an entire analysis to show why 1.Qxd1+ wins.
Okie. There can be a few continuations but I don't see any checkmate (Black wins a lot of material though)...
1) Qxd1+ Rxd1 Rxd1+ Nf1 g6 (Knight falls on next move)
2) Qxd1+ Nf1 g6
3) Qxd1+ Qf1 Rxd2

Rxf7 Kxf7 Qh7+ Kf8 Bh6# or Rxf7 Kxf7 Qh7+ Ke6 exd4+ Bxd4 Qxg6+ Bf6 Bf5+ Ke7 Qh7+ Kf8 Bh6+ Bg7 Qxg7# Nice puzzle.

Rxf7 Kxf7 Qh7+ Kf8 Bh6# or Rxf7 Kxf7 Qh7+ Ke6 exd4+ Bxd4 Qxg6+ Bf6 Bf5+ Ke7 Qh7+ Kf8 Bh6+ Bg7 Qxg7# Nice puzzle.
Defective solution.
Oh lol That's a terrible checkmate for sure. Whenever I try to solve long puzzles without a chess board, I fail miserably. Thanks for pointing out the blunder! Here's the correct solution.
