The difference between a best move and a brilliant move is that a brilliant move is the ONLY move that is winning and all other moves are either draws and/or losing moves. If you are in the position to make a brilliant move, you have no good moves, no excellent moves, and only 1 best move, which is considered a brilliant move. There are 2 types of brilliant moves, if you download the game PGN you will notice a brilliant move with either 1 exclamation mark or 2 exclamation marks. When the computer engine analyzes in a much deeper depth, the 2 exclamation mark !! brilliant moves are very rare and MUCH harder to find than the single exclamation mark.
That's simple not true, it depends on the engine's depth, if you set the depth higher, the engine will suggest the move and it won't be indicated as brilliant.

I see what you’re saying but like I said, it still only depends on the engine depth. Even if it is at max depth it might not be able to calculate enough moves for it to know that it is “brilliant”. By playing the move and you force the engine to calculate all following moves starting from that position (resettling the engine’s depth), if the engine sees that this move is better than the best move it was able to find, it’s a “brilliant” move. You can also just download the stockfish engine for yourself, set the depth to like 60, give it a couple hours of time and it will suggest totally different moves than the engine at depth 30. Of course it will take way longer to calculate and analyze the game and it won’t give you this handy game report card but that’s just because of chess.com limitations. Takes more processing power etc. So I would suggest you check out the stockfish engine for yourself if you’re interested, the link is: https://stockfishchess.org or https://github.com/official-stockfish/Stockfish for the source code.

I did brilliant move!Go to the end and 2 moves back!

I’m not positive about that, but here’s my take:
Brilliant moves are the best moves that involve a sacrifice. When playing a bot, Stockfish’s analysis, without hesitation, said that one of my moves was “best”, which shows that the brilliant was on the radar or the engine. However, when analyzing later, it was dubbed brilliant. Another example is when I had a checkmate in two that the engine clearly saw. It then dubbed my queen sacrifice for a back-rank checkmate a brilliant. That is why the phrase “that was a great move that was very hard to find!” Or “that was a truly amazing move!” Is relevant for sacrifices. Stockfish rarely misses moves, especially if one allows for the depth to increase. Of course, if a maximum analysis is run, then that is the cap depth for Stockfish. As well, if Stockfish plays someone, once in a while, the engine will play a move given a “brilliant” title that it clearly saw. As well, even if a brilliant is played, the analysis may favor you slightly less because although the move was good, it was not the “best move”. In simple terms, chess.com states that a brilliant is “when you find a good piece sacrifice”. (https://www.chess.com/forum/view/game-analysis/brilliant-moves-in-new-game-analysis-report?page=26) It is important to note that chess.com favors lower-rated players when giving brilliants, meaning that a brilliant for a 600 would only be an excellent, best move, or great move for a 2,500. Therefore, it is my conclusion that brilliant moves are the best or an excellent move that involves sacrificing a piece, while qualifying for a “good-enough” move that varies due to rating, a relatively gray area that may be determined on the spot.
NOTE: The app and website have different manners of handling the brilliant classification, so different moves might be classified as brilliant on both platforms.

I have many brilliant moves and if you want, you can check my forum post "puzzle on my game" in more chess puzzles
a brilliant move is a a sacrifice and the best move at the same time.
A great move is a serious game changing move and the only move
The best move is the top engine choice, but it's not seriously changing or a sacrifice, and unlike great moves, there could be two of them

Brilliant moves don't have to be best.

@snoozyman - This video you site has a couple of mistakes in it as far as commenting on the analysis and also on why the move was brilliant. The person commentating has no affiliation with chess.com. Chess.com has redefined Brilliant moves and defined Great moves here:

Wooops. I scrolled to the end of page 1 of comments and thought that was everything and commented above, but now see there are pages 2, 3, and 4 of comments also. My previous post might be redundant.

Brilliant moves are moves the engine didn’t really detect. The engine calculates to a certain depth after that it does not calculate any further moves, higher depth the longer it takes to calculate of course. If a human plays a move, it forces the engine to reset it’s depth and calculate all new possible moves starting from the new position. The computer might suddenly see that the move played was better than the suggested best move, hence brilliant moves can’t be suggested by the engine and only humans can play them. Even if the move seems “obvious” to us, the engine might have spotted another move that it thought was the best, until of course it is forced to recalculate. I hope this could help!
I believe you were right, however, they changed the algorithm to simply detect a piece sacrifice for winning. That's why nowadays, most brilliant moves are piece sacrifices. However, there is one other condition, which is that if you did not make the brilliant move and instead played the other best move, you cannot still be completely or significantly winning, or it would disqualify that move as a brilliant move.
There is one hidden secret which is that the game review tries to be more lenient for newer players and stricter for higher rated players.

That first one may not feel like a brilliant move, but it's an important pattern to recognize. That's why it comes back again and again in puzzle rush. This position was straight out of the puzzle rush database.
The second one is actually quite brilliant. If only you had realized why exactly during your game...
I knew how to win the game after.. i did find Qh5+.. and won the game.. but still why is my rating still bad
The thing is, just start a new acc
