Brilliant Moves in New Game Analysis Report
''Correct me if I am wrong. Have you ever seen the engine proposes a "Brilliant" move as "Brilliant" or as "Best"? I believe NEVER.''
I haven't either
I've seen it plenty of times, it will comment it something like "There was a hard to find move available there".

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.
Incorrect.
They have to be the best move.
I swear I saw a brilliant move that was second choice of Stockfish
Possible. That's what happened to me before. I played a "brilliant" move, but the engine has an even better "best" move.

Maybe the "best" move is an alternative. The "brilliant" move is a piece sacrifice with a crazy idea that can only be preformed with said move (such as my rook sacrifice)

A sacrifice is a brilliant move
No, even if a sacrifice is the best move, it is not going to show a brilliancy for it. I litterly sacrificed my bishop 5 minutes ago and even though it was the best move, chess.com shows that it was best. Although, if it's a draw but a sacrifice gives you a big advantage they will say that it is brilliant. Depends on the advantage and how good the second best move is (forgot to mention that but you might understand what I mean).

Eric Rosen moment. I moved the king. After they took my queen, I gave a double check, and the next move was checkmate.
1. Kf2? Bxd1?? 2. Nf6+! Kd8 3. Re8#!

Before trading queens, I played a very hard-to-find move.
I sacrificed THE ROOK
This was a brilliant move. It was also the best move.
