Brilliant Move?

Why was this love from my opponent considered brilliant? He blunders his Queen.

Probably one of my best games. Against a opponent that is stronger than me and I was losing.

Mate in 1, I found today

I'm only 500 ELO, so pretty pleased that I saw this one

White to Play, Mate in 2

Oh no

They fell for it. They said “Wow” and resigned immediately after

My weirdest looking checkmate yet

Why would Black play this?

I was playing computer and it played this move and I mated in 2. But for life of me I can't figure out why it would move the defender. Is there actually any tactic I am missing?

might not be very impressive, but I found my first forced mate in more than two moves

How does this qualify as "brilliant"??

I am not a chess beginner, but I do have many questions
