Game Review of missed Great or Brilliant moves.

Maybe this has been discussed previously; I don't know as I don't use the forum often.

But when analysing a game, probably like most of us, I look at any Great/ Brilliant moves and try to understand why they are such, and then look at 'good' moves and worse, and try to understand what I missed, and why the best move is the best move.

My question however is would all those suggested best moves be analysised as a 'Best move' if played, or would some of them be a 'great move' or even a 'brillant move' and how would you know? 

To me it would be great if chess.com would add this in, to see how many we humans miss...

A "great" move is more like a "critical" move; it is either the only move in the position that doesn't lose (or, in some cases, draw), or the only move in the position that wins, draws (in a losing endgame position), or otherwise gives you an advantage/equalizes after a mistake is played. So, if the coach says something about "missing the only good move," the correct move is likely "great."

The definition of a "brilliant" move was significantly dumbed down because people got mad about never getting one. But to put it simply, if you're not completely losing and the game is telling you to straight up sacrifice a piece, the move suggested is likely brilliant.
