Brilliant Moves
Everyone probably is fimiliar with the Brilliant Move, but really, what is it? What makes a brilliant move a brilliant move? Probably most people think it is a sacrifice to gain an attack, but some games I've seen had brilliant moves without sacrifices. At first, I thought the same thing, with this game I played against @Maxsufeng, where I sacrificed a piece and it said brilliant.
But later I found a game like this.* It appears too often, and simple sacs aren't really brilliant moves!

So the finale question is, What makes a brilliant move a brilliant move?
If you know, please put the answer in the comments, I would really appreciate it!
