How do brilliant moves work?

I've gotten great moves before, and I don't even know how I did that, but how do brilliant moves work?

u need 2 plays moevs that even the eginen didnt see

so basically I'm not gonna get a brilliant move any time soon lol

A brilliant move is mostly seen by the engine, but it’s a really hard-to-find move, like a sacrifice to get mate or win a piece. You don’t really need to play 2 super good moves to get a brilliant, also finding the only key move after your opponent blundered could be a great move. For example sacrificing your queen in a smothered mate (the famous one) is brilliant

If you mean in a Game Review here, it's a move that sacrifices material or allows material to be captured and is considered good or best.

Brilliant moves are sacrifices that if opponent accepts (takes the bait), result in a far greater reward like bigger material gain or checkmate. In-between silent moves that lay a trap can also be brilliant.
Here's a game where I made 2 successive Brilliant moves:

How to get a brilliant move:

1. Don't be @linorder

Brillaint moves being somethign the enigine didn't see is a myth. They are good sacrifices, and sometimes they aren't even top engine move.

You make a move that sacrifices material to gain a checkmate or material or a move that puts your opponent in zugzwang. Its pretty much a move that is the only good move or a move that gives you material/checkmate.

It is a sharp sacrifice that often leads to an attack or wins material.
