Hello guys, today i played on my alt a game. I did a move that should be considered an brilliant move, however it wasnt. A brilliant move is when for example you make a sacrifice to get in better position (for example winning a queen). I attached the game below and i would like to expand on the subject. On move 14 i saced a knight, in a sense that if pawn takes i take back with bishop swering king and the queen which would make me win a queen. That is obvious brilliant move but it was only marked as "good". Can someone explain why??

It has to also be the best move in the position to be considered brilliant.
