Chess Insights VS Lichess API : Lacking games on Italian Opening (C50)

[remi-picard]

Hello,

I discovered Chess Insights last week. Congratulations for this awesome feature ! At the same time, I also made some analytics with Lichess API (Export games of a user - https://lichess.org/api/games/user/{username}) and Pandas. I found some differences between my analytics and Chess Insights.

For exemple, Chess Insights doesn't find my games on Italian Opening (C50) with Black. https://lichess.org/insights/remlebarbare/ratingDiff/opening/opening:C50/color:black

My analytics found 7 games (all rated and played with Black in Blitz) : https://lichess.org/ZHmujiv4 https://lichess.org/geqYBymE https://lichess.org/mvxlu0aX https://lichess.org/mvauiP8R https://lichess.org/hF8rHnkb https://lichess.org/gfZ7B3g8 https://lichess.org/Ell3ARLH

Here you can find my games and stats on openings in CSV format games_and_stats_remlebarbare.zip

I found a similar issue about lacking games : https://github.com/ornicar/lila/issues/5704

Regards, Rémi

Hi, thanks for reporting. Looks like it may be becasuse those games don't have computer analysis (with the exception of https://lichess.org/Ell3ARLH, but it may not have been analysed at the time).

@niklasf Thank you for the reply. So only games with analysis asked are visible in chess insights ?

Something strange is that there is still no games in https://lichess.org/insights/remlebarbare/ratingDiff/opening/opening:C50/color:black (I expected to have at least the analysed game https://lichess.org/Ell3ARLH).

Maybe I misunderstand one thing. :)

Yes. Can you try to click the "Update insights" button? If the analysed game does not appear, something else must be going on. Please let me know and I'll reopen in that case.

[remi-picard]

Yes, I updated insights. Nothing changed in chess insights.

I have just analysed a second game of the previous list (https://lichess.org/ZHmujiv4 - the victory against the emperor Charles Quint ! ;)). Nothing changed also.

Maybe there is a batch updating insights to wait ? Chess Insights worked for old games (these games have some years) ?
