Evaluating Elo rating on a per move basis I've been a Chess.com user for a little over 3 years now. I play EVERY day, usually have anywhere from 10 to 50 games going on any single day.

Since I've started, my rating has only gone up about 150 points. For the past 6 months, my Elo has stayed fairly close to 1400.

I know Chess.com has the feature of evaluating the games that I've played and suggests what I did wrong, but I have to request all of those games to be reviewed.

Is there another tool/app that can evaluate the strength of individual moves during each and every game, that would tell me the "strength" of the move? For example, if I stupidly put my queen in a position where the opponent can take it, then that's a blunder and would be rated very poorly.

Or, is there a way to automate all of the Chess.com games to be reviewed by the engine to determine how I did in each?

To be able to evaluate the strength of individual moves, one needs to estimate the difficulty level of the position. This estimation rests on two ingredients: the ability to evaluate the position (almost) perfectly, and a sample of responses for that position from a pool of players with different strength. This is thus an empirical question.

For tactical training, there are straightforward implementations, such as this one:

You can add to the accuracy of a solution a time element:

For any kind of position, I believe it's still an open problem. 



A related question is the optimality of play. To that effect, Guid &amp; Bratko did an interesting study:


  The basis for their evaluation was the difference between the position values resulting from the moves played by the human chess player and the moves chosen as best by the chess program Crafty. They compared the average number of errors in the player's game. Opening moves were excluded, in an attempt to negate the progress in chess opening theory.

But such study cannot estimate the strength of a player as requested by the querent. It can only evaluate optimality of play, and order players according to this evaluation. This does not give ELO or complexity of any given move.
