New Analysis - What is a Brilliant Move?

The top most level on the new analysis is saved for Brilliant moves? Below that is Best Move.

So is a brilliant move even better than best move? But that doesn't make sense.

A lot of this doesn't make any sense...There is no reason to break moves down into this many categories.

Obvious moves are called brilliant moves? What are you even talking about.

My understanding is that brilliant move is equal to best move, but just that it was deemed to be hard to find. Maybe something like giving up a piece to get a superior position or something.

I got one in a 15/10 game. I'm sure it's not impressive as I'm low rated, but I'm happy my tactics exercises are paying finally.

I have only ever seen 3 moves listed as brilliant. 2 of my own and 1 from the opponent. Two of these were pawn moves. One seemed a regulation recapture. I forget what it was a piece or another pawn, but it was a recapture that kept material equal.

There were two pawn that could have done the recapturing and both seemed equal, but the way it was captured in the game must have been part of some fancy line as it was classified as brilliant move.

I have no clue why the computer loved it so much.

Then one instance was when I pushed a pawn to f5. The computer fell in love with that move. It was not a bad move, hell I played it, it made sense to play it. However I when playing it never felt I was playing some great Einstienic level move.

Lastly there was a move Qa4 or Qa5 (or h, depending on the color, can't remember). What I remember is I put the Q on the left most file. Anyway it was a tricky move, I will admit, but even then I never thought it was so good that it would get a brilliant (!!) tag from the computer.

I think its all very random how the computer gives those tags, and I still dont get the whole brilliant move.

Of course these three brilliant moves were in three seperate games.

I wondered the same thing after this showed up in an analysis of a game I played:

Maybe there should be a ”worst move” category, and then ”blunder” only for those that are worse than that :-)

Excellent move I get. Very good move, not the best, but still one that keeps your edge. However we are discussing 'Brilliant' moves which is a whole diff. category.

Probably brilliant moves means exceptional moves - not bookish.

In the game mentioned by DreamingMillion white has many alternative moves. Am I right?

Okay solved.

Hover you mouse over the part it says brilliant move. It says - brilliant move is the best move but one which the computer feels is very difficult to find.

There should be a category for moves that significantly changes the computer evaluation for the better. Currently, it is only looking 20 ply in a very selective way. This is not very deep and on rare occasions -- for example when I play a sacrifice that looks good in a complicated position -- the evaluation will go from, say, 0 to +3 after my move. It is not often that I manage to find a move the computer does not see, but I think "brilliant" should be reserved for when that happens.

I feel its not really you who played the +3 move, rather, its your opponent who made the mistake and changed the evaluation. The move you played has to go under the "excellent" category

It's subjective.  Someone, in this case the computer program, determines that a move, although not the best, had a significant impact on the game and was hard to find.  There's a story about a grandmaster who made what he thought was a blunder.  He somehow won the game.  At the end of the tournament he was awarded a brilliancy prize for the deep sacrifice that he made (the blunder).

Great move indeed. However, I still feel it's your opponent who allowed this and the positional evaluation itself is +18 for black.

I've finally had "brilliant" moves show up in an analysis of one of my games (one by me and one by my opponent). I wasn't surprised given my rating in the 1200s that I hadn't see one yet as neither me nor my opponents are that good. So imagine my dismay when the moves labeled brilliant, while clearly the best moves, are not particular hard to find moves. Both are obvious captures:
