Promotion to knight is best move?

I did this as a joke at first, then the engine said it was the best move.

I’ve got my first Brilliant. 3 to be exact. I still don’t know why.

Won a game - opponent had zero mistakes & blunders

I'm quite proud of myself. Can't remember I ever beat someone who did not even make a mistake.

Didn’t even see that I technically sacrificed my bishop as well

Gothamchess would be proud of my move here

To be fair I didn't calculate this all the way. This came out of the "boring" London system opening.

I JUST BEAT NELSON

I finally managed to reach 2000 puzzle elo

Best next move?

I am black

One of the most satisfying fork I have ever got

Yes
