Brilliant Moves

I've played quite a few matches now, and reached my level, getting stuck between 1100-1300 in rating for Rapid. I have yet to see a brilliant move from either me or my many opponents when I look at the after-game analysis. But in this game my opponent made two, and I don't udnerstand them. Why are they brilliant, they don't seem so special.

What are the criteria for a brilliant move in the Game Report after a game?

Only once did I see a "brilliant " move...there was NOTHING brilliant about it. Opponents king / queen against my king....nothing else. Queen checked my king over and over...but all of a sudden one boring was BRILLIANT...so what ?

yeah i've seen the computer give a brilliant move for someone moving their queen that was attacked before. idk why that was. 

I believe a brilliant move is the end of a series of best or good moves.  The only brilliant moves I've seen pointed out were obvious or forced moves.  Nobody is brilliant just getting their king out of check or trading a piece.  I've made a move that added 20 points for me on the evaluation bar in the mid game and it was just a best move. Meanwhile I got a brilliant move which didn't change the evaluation bar.
