Answers.Text: Agreed. It seems very unlikely to meet the new threshhold by itself:  "Chess.com labels a move as 'brilliant' (!!) when it sacrifices a piece, is best or nearly best move in the position, does not result in you having a bad position, and where you would not be completely winning if you had not found the move. This is defined more generously for lower rated players and stricter for higher rated players" [(from this post)](https://chess.stackexchange.com/q/41396/26335).

  No. Delivering checkmate via en passant is not a sacrifice, and "sacrifice" is part of chess.com's definition of a brilliant move.

  The criteria for a move to deserve a double exclamation mark have to be more than just being the best option in the position --- that's merely not making an error. So there must be some criterion based on further play. But after checkmate there is no further play. So no sort of checkmate move can be a brilliant move.
