What qualifies as a "brilliant" move?

Ok

Yes.

It is a myth that brilliant moves are better than the best move. Brilliant moves are just sacrifices, and half the time the enging sees them. Also, there are many instances in which the brilliant moves are actually worse than the best move.

I've saw Emir (lvl elo 1000 bot) play ONE Brilliant move but still, he lost to me so easily idk why

Brilliant move is roughly, when you ignore something obvious and principled and find some positional alternate which would affect position in later phases of game..

What? What does this even mean?

My most recent game to have a "brilliant" move (I do not get that many). Move 14. I don't think it was "brilliant" though it certainly won the game for me - a bishop sacrifice with check that meant the opponent's queen was taken.

i sacrificed my knight it turned out to be a brilliant

A great move is the only good move in the position, or one that changes the game (gives you a winning position, gets you out of a losing position, forces a draw while down material, etc.)

A brilliant move is any great move that involves a material sacrifice.

This part is not accurate. The actual definition is known to be much more loose than this. Pretty much "any sacrifice that is good". It doesn't have to be the best move. It certainly doesn't have to be the only good move.

Oh, neat. I usually don't get awarded brilliancies for sacrifices that are ever so slightly inaccurate, or if I'm already crushing.

If you're already overwhelmingly winning, that disqualifies any move from called "brilliant". On the other hand, there are plenty of examples where 2nd or 3rd best moves were labeled "brilliant", including some sacrifices that made no sense at all.

A "brilliant" move is characterized by its strategic impact, creativity, and effectiveness. It involves innovative thinking, leveraging unique insights, and anticipating future outcomes. Such a move often resolves complex problems, seizes opportunities, or gains a competitive advantage. It demonstrates foresight, adaptability, and precise execution. In various contexts, including business, sports, or personal decisions, a brilliant move stands out for its exceptional thoughtfulness and positive results, setting a benchmark for success and inspiring others.

This AI-generated nonsense has nothing to do with reality. It's just pure spam.

a brilliant is an amazing sacrifice

Since I started doing game reviews on chess.com (not all that long ago though over more than one account) I have had perhaps seven brilliant moves. Most were sacrifices of one kind or another. Not all of them struck me as "brilliant" though most were perhaps "great".
