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:
...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.
