Fun win in my game, white to move

What about it?

U may enjoy the heck out of my edited chess.com image. 850 rapid fire those curious

How is this checkmate??

Made a mate in 3 puzzle inspired from post by u/Satankid92 , see how many of you can find it, black to play

My game. Black to play and force mate.

I was so proud of this mate but didn’t have anyone to share it with during the dark days

All my games when I'm sleepy

What are some things I should be doing in this position? I always reach this in the early game, but I fall apart after this. I'm playing a 2000 rated bot

Am I missing something? Can’t the Queen just move to d3 and checkmate?

Nothing crazy, but a solid few months of improvement I am proud of. Consistency is key!

Opponent annoyingly tried to play for a stalemate, but eventually had to succumb to defeat.

Why sac this knight for little to no reason is the best move ?
