I've gotten 2 brilliant moves in a game too but it happened only a few times. Usually it's 1 or 2 great moves and 0 and sometimes a brilliant one.
But that was an intense position! Great decision to play c6 to free up that DSB later. And you got the octoknight.
The moves aren't really brilliancies because if you think according to danger levels, threatening mate is always better than any other move besides defending an opponent's mate. But still they are great finds and show the right attitude to chess thinking. It's all about the mates (the rest is treble).
I got 4 in one game today. https://www.chess.com/analysis/game/daily/443525981?tab=review
