It was a clear practical decision but it was not "brilliant" because you were already "completely winning" without it. The engine said you were +6.

From the Support pages:

Brilliant Moves are always the best or nearly best move in the position, but they are also special in some way.

 

We replaced the old Brilliant algorithm with a simpler definition: 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.
