You are almost done.
But, this is the game that can mate in 3.

Nh4+ is not a checkmate.

After 2. Qxe6+ it's forced mate any way Black chooses to play.
Possibility #1:
2. Qxe6+ Kxe6 3. Ng5# 1-0
Possibility #2:
2. Qxe6+ Kg6 3. Nh4+ Kh5 4. Qxf5+ Kxh4 5. Bg3# 1-0
Possibility #3:
2. Qxe6+ Kf8 3. Ng5 ===> After this, Black has no defense, any move will result in Qf7# 1-0

But maybe there's even a more efficient way to force mate than 2. Qxe6+?
Right Answer!!!
Alekhine won by playing possibility #1
1. Nf7 Kxf7 2. Qxe6+ Kxe6 3. Ng5# 1-0

I did not want to finish it. I saw the moves and realized I had seen the game before. I left it to the readers after showing move 2.

In most games of GMs, they resign before checkmate.

His opponent wasn't a GM though (as I recall, this was played in a blindfold simul!).
