Why Brilliant?!

Been getting a lot of brilliant moves lately, just wondering what really classifies it as brilliant move

For example, I got a brilliant move in an OTB tournament recently

https://www.chess.com/a/28BF8Q1z6ALZ4?tab=review

Here, I played with the white pieces, and move 9, d3, was supposedly a brilliant move. In this situation, d3 looks like a normal move that any person would play to bring out their bishop. Somehow, it is "brilliant." 

Another instance was in a rapid game I just played after the time of posting.

In this situation, I also played as the white pieces, and on move 19, Nxc4 was a brilliant move. Here, I understand that his move is harder to see than the 9. d3 in the previous game. But, it doesn't seem to increase the evaluation too significantly.

Finally, in a blitz game, I played as the black pieces, and the last move, Qxb3+ was also classified as a brilliant move.

Qxb3 seems to be a relatively simple mate in 2 that isn't so hard to find, and in situations like this before, the move I played was either counted as a "Great Move", or a "Best Move."

In these three games, I feel like the moves that I played all varied in difficulty level to find, so why are all three of them considered brilliant moves?

I also tried searching it up, but the answers varied. 

Thanks.

Well, the definition of a brilliant move is a move that sacrifices material and is good or best, so all three examples would classify as a brilliant move.

Each of those moves sacrifices material is one way or another, and none of them are objectively bad moves.

The first game doesn't seem to sacrifice any material...

I've also sacrificed pieces in a good position that led to an advantage, but I didn't get a brilliant move.

brilliant move criteria is it has to be the best move, and it has to be sac

that's literally it

even if its tied for the best move

It doesn't have to be the best move. Occasionally you see "brilliant" moves that are not in the top 3.

in the first game you posted, if black takes the bishop sacrifice, Nc7 forks K-Q-R; they didn't take the sacrifice and avoided the fork, so you kept your bishop - but I think that's what makes d3 "'brilliant" in this case

Ah, ok. Thanks everybody!
