I thought this was a mistake. Why is this move brilliant?

Blundered mate cause of a misclick feelsbadman

Satisfying check mate

Nice mate in 2

Is there a name for this pawn formation?

First international brilliant!

It was against just a 700 elo bot lol, but I’m still proud of it. I’ve had brilliants before, but they were either totally accidental, or just me finding a decent-ish move. With this one I was very certain it’ll be a brilliant, and it was!

Ever seen a mate like this?

Advantages of kings indian The strong bishop

Another never resign

Down 13pt material, only 1 minute left for me That brave Pawn h6 saved my ass.

Why is this not a brilliant move? (I’m black)

Can someone explain what happened

I ran aot of time yet its a draw by timeout vs insufficient material . Don't get me wrong I like the fact that I didn't lose but I want to know what happened.

How is Qc6 not checkmate? It's says M4
