Brilliant Moves in New Game Analysis Report

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

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.

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. 

Most of the time they have to be. But not always. I have before that there's a move which is "best" (6+) and my "brilliant" (5+). Also, it does not have to be a critical move.
