Opening Database from your own Games

#1

Hey,

is it possible to create an opening database from your own Games? Pretty much like the regular one but instead of taking all lichess games or certain GM games you only take your own Games.

This way you would be able to see how play against certain positions and how well you do that.

Like "after e4 c5 I usually play d3 but I end up losing 30% of my games if I play d4 instead" or whatever.

Greetings

#Edit: I do realise that you can some of these information with chess insights but only for a certain opening, not for a concrete line.

You can download all your lichess games:

https://lichess.org/api/games/user/Mc_Muffin

Next, open that PGN in Scid:

http://scid.sourceforge.net/

Create another database in Scid format, drag the games from the database symbol of the pgn onto the symbol of the just created database (button top left in the game list).

Then you can filter that database by board position (button bottom left in the game list). This will show, how you score in the current board position (button secondmost bottom in the game list).

Strictly spoken you can also filter PGNs, but the Scid database format performs better and you can delete games from those databases.

Actually you need to create two databases, one for your white games and one for your black games. To do that

  • rightclick on the headings in the game list of the pgn -> 'Reset sort', then sort by white player
  • scroll to the first game where you are white, rightclick the game above -> 'Filter' -> 'Remove Game and all above it from filter', do the same with the games below the last where you have white. Now the filter contains just the games where you are white.
  • Export these games to a white games scid database.
  • rightclick into the game list and select 'Filter' -> 'negate Filter', then export these games to a black games database.

If you intend to do it seriously, you can look in Scid at the games where you score bad, find the first position where you erred, check with the engine and figure out a better variation.

Then navigate to the start of that variation, copy the position to the clipboard, paste it as an interactive exercise into a Lichess study, insert the better moves, train these interactive exercises from time to time when logged off.

I used to use a commercial software for this, but i found Lichess studies to be better, because the chapters can be sorted over time, so that i do not lose the overview.

I made the experience that i often do not have to repeat those exercises because the process of inserting them into Lichess and giving the chapters proper names is often enough to get these ideas into my brain.

First of all: Thanks for the feedback.

Doesn't this sound like a feature that's worth implementing into lichess? Though I haven't tried your solutions yet it does seem rather complicated. And I could image it's not too hard to implement this into lichess given you already have the code for databases and the information from your own Games (even though I have not once looked into lichess source code...)
