Opponent played the only losing move

What about it?

Of the 12 possible moves he could have played, he played the only losing one. Opponent was rated 1410 and I'm currently 1362 on Lichess.

How is this brilliant. I know a lot of people ask this but…

How is this a brilliant move

One move retains equality, from a game I just played.

My opponent (white) just resigned in this position, was it too early?

i won, but i missed the mate in two here....

Accidental stalemate while my opponent had just 0.08secs remaining on the clock ☹️☹️

30 minute game. He spent ages on all his moves, hung his queen and mate.

I didnt even know +31 was possible with equal material

What about it?

i though i trapped the queen but opponent showed me otherwise

Bro gave up in less than 15 moves.

What about it?

He made 3 blunders and I ended up taking 2 of his knights and his Queen.

White to play. Do you see the brilliant move?
