Game review

I did a smothered mate, and the queen sac is not even a brilliant anymore

Oh

Because you were winning already.

yeah, a brilliant move is a great sacrifice, and every smothered mate of these kind involves a queen sac. So i'm just saying that the way chess.com determine a brilliant move might be flawed, or maybe is because when you already have a brilliant move in the same game, chess.com will hold back when giving you another

it says:

which means that the move could be worthy but it needs further analysis

CHESS.COM, 2022:

"As popular as the "Brilliant" move has been, we've heard your feedback that "Brilliant" moves can be too rare and sometimes not that brilliant. We agree and we've updated the way that "Brilliant" moves are recognized. The new game review has been fine-tuned to better understand what humans identify as a brilliant move. "Brilliant" moves must now sacrifice material in some way and must be the best or nearly the best move in a position. "Brilliant" moves will also be a bit more generously awarded for newer players, recognizing that some strong sacrifices that may be standard for experienced players are quite an achievement for newer players. We think you'll love the update. Try it out and give us your feedback."

The mates that are common and are mentioned in every book like the Anastasia mate and smothered mate
