What qualifies as a brilliancy?

I think a Brilliancy depends on the Depth of the engine you are using. Run game analysis on the lowest depth setting, and play a great move, I mean like the best move you can find, and it has to be somewhat tactical. You'll get a brilliancy. A brilliancy is mainly a move that it did not consider winning a few depth plys below, but it can see it is the best now. This mainly includes tactics that are 2300+ according to the Chess.com rating scale, and you are running Game Analysis at the lowest Depth. Each higher Depth setting will increase the skill required to get a brilliancy

This is twin brilliancies.

I don't think brilliancy really matters. Its according to a computer, which only has one playstyle, which might be innaccurate etc.

Also, its a double brilliancy bcuz the point is u sack the ruk

I've played games better than that and haven't gotten a brilliancy

i suck

so no brillancy for me

I also suck and I made a position so confusing and hectic by using my own lack of skill that I managed to earn my first brilliancy: 13: Qh5+ in this game

i got the easiest brilliancy ever, its called taking a queen with a pawn 

I see, a man of culture.

maybe this can help: https://www.chess.com/forum/view/game-analysis/brilliant-moves-in-new-game-analysis-report 

I got mine when I resigned after computer's first move

but hold on, is stockfish updated every day or so? If that's so, it should learn from those brilliancies and consider them as best move in the next version.

A true brilliancy satisfies 4 criteria

1. It wins. Moves that lose or draw are not brilliant.
2. It is unique. When 2 moves win, then none is brilliant.
3. It involves a sacrifice: that is aesthetically pleasing.
4. It is a quiet move: no check (+) or capture (x): those are too obvious.

Here is an example:

Brilliancys are a sacrifice that is the best move or almost the best move

ea

Most of my brilliant moves, or even all of them, contain a sacrifice.
