I've been wishing someone would make something like this! Always frustrated me that tools like aimchess and openingtree only allow you to look at the two sources separately.. supposedly, at least in aimchess's case, the reason being that the rating systems are different.

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..

As you say, I currently don't. In the future I might check the correlation between chess.com/lichess (when enough users register). Then I should be able to even calculate the chess.com rating from a lichess rating and vice versa.

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.

Yeah definitely should be the focus! Would be excited to see some of the stats aimchess has implemented.. performance in various phases of the game.. tactics.. advantage capitalization etc.

I also found that when clicking through to an opening on your site, it would always say "no games find at this position". Bug?

[ThomasCM]

Thanks for the feedback. It's not really a bug. More of a communication problem... ;)

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...
