why is this a brilliant move?

Lost by time. Would i win? Black to move (900 elo lichess)

Finally some brilliancy on my chess career.

My very first, 300 elo 3min speed chess

First game of the day and I get threatened. 😭😂

What about it?

He resigned right after this. 💀

Tf?

What about it?

Like what

This is my first brilliant move but dont get why this is a brilliant move?

Is 0.0 accuracy possible?

What about it?

Yes.

Just thought I’d share this mate

What about it?

I was playing (against a bot) and tried chasing the king around the board until I stumbled across mate. Maybe kinda interesting?

For the first time, doing puzzles felt it helped me to mate!

I'm Black side and I played a friend that told me this particular game ends in a stalemate since I missed my chance to "checkmate him in one" by moving queen to f2 and went h3 instead. How is that possible? Even though I went h3 with queen, his king can still move to f4, so how is this stalemate?

What about it?

Title. Please tell me. He insisted that I missed checkmating him in one move, so by that logic it ends in a stalemate when he clearly has a square to go to? I usually play chess online on chess.com and have never come across this rule!
