Hello puzzlers,
2. -Qxf7
This is invalid. The black queen at d6 can reach e7 and f8 only.
If black makes Qf8 white checkmates with Qxf8.

Hello Dr. Z,
After your proposed:
1. Qxf6 Nxc4
2. Qf7
White threatens Rxh7++ or Rg8++ / Qg8++.
So black can reply:
2. ... Qxf7, and another key piece in the threat comes off the board.

Hello puzzlers,
1. Qxf6 (Queen takes knight.) Nxc4 (Knight takes bishop.)
2. Qf7
White threatens Rxh7++ or Rg8++ / Qg8++.
2. -Be6 (protects g8)
3. Rxh7++
2. -Qd7
3. Rg8++ / Qg8++
Black has only one move to prolong the game. It's Qxh2+. Then, white
replies with Kxh2.

Hello Dr. Z,
Since white's vital c4 Bishop is loose, Black's first move after Qxf6
should be:
1. ... Nxc4, now black has traded a knight for white's key bishop blunting
the mate threat.

Hello puzzlers,
Doctor Z is ready to operate. My solution is more direct. I suggest taking
the knight protecting the black king.
1. Qxf6 (Queen takes Knight.)
1. -Qxf6 (Black queen takes white queen.)
2. Rg8++
1. -Be6 (Black bishop blocks white bishop at Bc4.)
2. Rg8++
1. -h5 (creating escape square)
2. Rg8+ Kh7 (only escape square)
3. Qg7++ / Qh8++ (checkmate)
Note how Rg8+ employs the double check. The queen at f6 and rook at g8
check the black king at the same time. The black king must move because of the
inability to block check.
