The engine can find the Revised Brilliant Moves

Cornfed

Chessbase has incorporated that into their program...really easy to search an insane amount of games and have it flag 'brilliant 'moves'.

Best moves are the moves found and assessed as best by the engine (whether you played it or not)

Hence brilliant moves are only made by the human player.

The engine assesses a move to be brilliant only after it is played (can never be proposed as mentioned above).

The engine was capable to assess a move to be brilliant in comparison to its best move when it is played by finding the outcome to be better than the engine proposed (its best move).

Hence a brilliant move is one that is proven to be best only if the engine had gone into a depth that is further than the depth it traverses, but it does not. This is why it can only figure it out after it is played by the human player.

outstanding explanation!!thank you 

This is not true, I believe

Stockfish found 3 brilliant moves and 8 great moves against Lc0

So called "Brilliant moves" are not that hard to find

I know this game is vs computer so it's not cool, but I found some brilliant moves 20 mins, without engine. BUT, GET THIS, POST_ANALYSIS, THE ENGINE FOUND THE MOVE INSTANTLY

"Brilliant moves" are basically best or excellent moves which involves sacrifice, and are not losing.

"Great moves" are "by far the best moves"

My "brilliant" moves is just a simple sacrifice that avoid stalemate. The engine found it instantly.

Anyways, Stockfish played 3 brilliant and 8 great moves against Lc0 before.

How brilliant moves are calculated?

I think brilliant moves are moves that grandmasters would do in the case. Like, if you have the same position as grandmaster game, and you take the move, that's brilliant, because it's a grandmaster game. Or it could be a long term thing.

No, brilliant move can be easier ones when played by lower-rated player. The game review "brilliant moves" are not that hard to find.

Pzxchess

We replaced the old Brilliant algorithm with a simpler definition: a Brilliant move is when you find a good piece sacrifice.hese are moves that were critical to the outcome of the game, such as going from losing to equal, equal to winning, or finding the only good move in a position

That's a link, chess.com explains

@poonzhiken I think what happened is that since you rook sacrificed, you removed threat from your pawns, and could easily promote to queen

Brilliant moves are moves that have a sneaky/hard to find follow up but that have nice logic. ALTHOUGH THEY ARE NOT NECESSARLY THE BEST MOVES.

I think so. I just don't get the nice logic part. Can the game analysis access "nice logic"?

Incorrect. 

They have to be the best move.

My guess is they're a game-changing move - in terms of material, space, ...when one had the advantage and it shifts suddenly.

It's often described as "the only move" in game reviews, so it suggests any other move is a mistake : there is only one really good move you have to find ! With best move, there are usually other good moves, it seems.

Creating a passed pawn will count, I also got a brilliant move for taking a bishop my opponent left hanging.
