Chess.com is brilliant, and I use it as well as the less popular (but also brilliant) Lichess.
Lichess is "cooler" because it's non-profit but honestly, comments like that are reminiscent of the childish anti-Microsoft barbs from Linux ideologues that have thankfully declined in recent years.
I have fallen in love with chess again over the past few months, and lichess is an absolutely amazing experience. Their mobile clients (iOS/Android) are both fantastic and BS free.
Here is an example for the current world champion: https://www.chessmonitor.com/u/kcc58R9eeGY09ey5Rmoj
How do you unify ratings?
Edit: ah I see you don't, makes sense I guess. Might be interesting to have them both on the same graph even if the y axis is different..
But there are many other features I want to implement first. I'm currently more focused on the statistics part than on the chess.com/lichess relation.
I also found that when clicking through to an opening on your site, it would always say "no games find at this position". Bug?
The openings page list your openings for white and black. If you click on an opening it takes you to the explorer which shows the stats for only one color (white by default). Therefore, if you play an opening for black a lot it will appear in the list of your openings. But when you click on the opening, the explorer will show your stats for white.
There is also another problem, that the detection of openings (on the openings page) respects transpositions [1] while the explorer does not.
Maybe I'll remove the link to the explorer as this seems to cause a lot of confusion...
I did some research (mostly on the online-go.com forums) and joined lichess.org and haven’t looked back since. Superior in every way.
Perhaps I should thank chess.com for being so annoying, if it weren’t for their constant nagging I would probably have stayed on the platform and never discovered lichess.org.
