Comments.Text: @paulgarrett Alfil cannot promote and only has access to 8 of the 64 squares.  Then again a pawn could only promote to a fers, and Wikipedia's Alfil article suggests that an alfil was still more valuable than a pawn.  Since the OP has now specified modern chess I suppose its moot whether an alfil sacrifice would count as "brilliant".

Comments.Text: Now the "definition" has been added the question is, IMO, impossible to answer - the "definition" is just not well enough, err, defined. Presumably chess.com sticks it through an engine and applies some algorithm to the numbers that come out. What is that algorithm? Once you have that download some of [Greco's](https://www.chessgames.com/player/gioachino_greco.html) games and see if anything comes out as a first stab.

Title: What was the first brilliant move ever recorded?
ThreadText: # What was the first brilliant move ever recorded?
  
  (Asked by: username_0 on 2024-06-19)
  
  What and when was the first brilliant move recorded in modern chess?
  
  This would be based on Chess.com's newest definition of a brilliant move. Not just in chess.com games, in all games.
  
  For reference, Chess.com's [latest definition of a brilliant move](https://support.chess.com/en/articles/8572705-how-are-moves-classified-what-is-a-blunder-or-brilliant-etc):
  
  > ...**a Brilliant move is when you find a good piece sacrifice.**
  
  > There are additional conditions:
  >
  > * You should not be in a bad position after a Brilliant move
  > * You should not be completely winning even if you hadn't found the move.  
  >   We are also more generous in defining a piece sacrifice for newer players compared to those who are higher-rated.
