What Exactly IS a Brilliant Move?

Black’s move here was brilliant. Why is that?

Brilliant moves occurs when you or your oppenent makes a Great Sacrifice! For checkmate or either better position, but sometimes it can happens without a sacrifice if stockfish sees that, if it has an advantage

Black didn't care about his rook and "sacrificed" it for a reason, it can lead to checkmate or gives him and advantage and that's why it's a brilliant

But i don’t see what that does for me tho 😭🙏 please someone tell me

Your move is the only one that keeps the game completely equal. Anything else is at least a +2.4 advantage for your opponent. After that, it leaves both sides having to be mighty careful, as doing the wrong move gives the advantage to the opponent.

This hardly seems brilliant though. Usually, the only good move in an otherwise poor position gets a "!" at best. This pawn move not only falls into that, but it's a pretty obvious move that just about anyone would do, even if they didn't realize it was that good.

Black left their rook vulnerable to being captured by horsey. That's why that was brilliant move. Also, as Fr3chToastCrunch mentioned, it was the only move that keeps the position equal, and doesn't lose the game

It can't happen without a sacrifice. That's the definition of "brilliant": a sacrifice that's good.

Also, Stockfish has nothing to do with it. Engines don't use adjectives like that, only numbers. Chess.com has their own script and that determines which moves are brilliant or not.

I also want to point out the fact that my opponent was able to trap my queen…was that it? (I’m 13 and i feel kinda stupid if that actually is it. They didn’t tell me anything…)
