It seems pointless to discuss chess.com without mentioning the paid features like game analysis which are much more user-friendly than Lichess.

Agreed. The post-game analysis on chess.com will make you a better player faster. It automatically turns your key game moments into chess puzzles.

Lichess does this as well, and it's completely free. It's the "Learn From Your Mistakes" button visible after you've performed computer analysis of your game.

I find game analysis in lichess much better than chess.com's. The advices it gives out are usually rubbish.

For one thing, framing your accuracy in percentage instead of the obscure "centipawn loss" makes understanding how well you played much easier. BTW I've compared their analysis on a number of games, and it seemed like lichess is much tougher on you in what it defines as a blunder.

I disagree, ACPL is a well defined system, while nobody really knows what the accuracy means or how it's defined.

1 CPL, in short, is the loss of 1/100th of a pawn. Take the average of that and you get ACPL. So a ACPL of 100 means that you on average lost one pawn on every move (of course this isn't literal) that you played.

I've read the meaning and I can tell what the numbers mean, but it's still less intuitive than percentage.

[aflag]

Interesting, I find the exact opposite. Measuring things in terms of pawns give me a feel of how far behind I was from optimal play, whereas with the percentage, it's quite abstract. What does 70% accuracy mean?

[dvirsky]

That you're 30% far from optimal play :)

[shukantpal]

Yeah but what does “far” mean. You have experience with loss of pawns but not distance to optimal play
