If you are familiar with watching chess broadcasts on ChessBomb, you'll know they have an engine running on the server which evaluates moves, and colors each move according to whether (according to SF) it was the correct move, an imprecise move, a mistake, a blunder etc. with colors ranging from bright blue (good) to bright red (bad). When switching to a game, one can then instantly see how well the game was played, and where a blunder/mistake may have occurred.

Does anyone know if a similar feature is available in other chess software or websites where one can upload their own games? And get such color codings for their own games?

I'm only looking for something equivalent or very similar to this; I know some software uses graphs to display the +/- score as a function of the move number, and some software can auto-analyze all moves and annotate it with ? and ?! and such. I'm not looking for that.

Edit: below is an example of what I mean, when viewing a game in the mobile browser. It instantly shows all the moves and highlights which moves were good/bad.

  • Checking with you before I post as an answer: Lichess's game analysis leaves a good move white, puts a blue mark for an inaccuracy, an orange mark for a mistake, and a red mark for a blunder. Would this feature be helpful/worthy of an answer?

  • @Brandon_J I'm mostly using mobile for accessing these sites/apps. I have the lichess app but I don't recall seeing such a feature in there. But maybe I didn't pay enough attention.

  • It's in there, I believe; I'll write up an answer at around 11 am Central US time.

Here's how color-coded analysis looks on the lichess desktop site.

computer analysis

As you can see, depending on the severity of the error (according to Stockfish), different colored bars pop up on the game analysis - blue for an inaccuracy, orange for a mistake, and red for a blunder. A black bar will show if a player loses a forced checkmate sequence or blunders into a forced checkmate sequence. I don't have the app, currently, but I believe that the same thing shows up there, since I used to play exclusively on the app.

You get this color-coded analysis by clicking "request a computer analysis" - it's on the bottom of the screen on PC.

If anyone has the app downloaded at the moment, feel free to screenshot this feature and add it to this answer.

  • Is this a recent feature? I had never noticed it until you pointed it out!

  • @itub not very recent. It's been around since I got my account - which was July of 2017.
