Feature request: practice openings against computer • page 1/1 • Lichess Feedback • lichess.org

Function whereby you can select the opening to play and your computer opponent plays different lines against you. The first moves could be determined by the main lines from the database. Different lines could be determined by % chance based on the same % chance that players use.

From the board editor you mean?

#2 I don't think the computer will make opening moves, it will only play its top choice. It's well known that computers don't evaluate the first moves in any chess game quite well.

Really? I assumed that was just because there are fewer choices in the opening.

#4 is correct (although AlphaZero internalized its opening book knowledge instead of referencing a book like every other engine does)

@pawngrid
this would be a very useful feature.
I use this feature already with the "SCID vs PC" program for opening training. I think it would maybe easy to implement in Lichess too. The most important is that you have a big Database and Lichess has a very big Database. So Lichess could make this better than anybody else.
The very cool thing is that you can choose at the Lichess Database also the Average rating and time control. So you can for example simulate playing against a fast and strong bullet player without having to be fast (and strong) yourself.

How do you use the opening trainer in SCID vs PC? You just select the opening and it uses the database moves? Does the difficulty affect those opening moves?

@pawngrid

in SCID vs PC:

Open a big database or a special small one with games whose openings you want to learn.
Open up the Tree Window (click the tree icon, go to Windows -> Tree Window, or just type Ctrl-t).
Once the Tree Window is open, click the light bulb icon to enter training mode. All of the moves and ECO codes will disappear.
When the Training button is selected, Scid will randomly make a move every time you add a move to the game. The move Scid chooses depends on database statistics, so a move played in 80% of database games will be chosen by Scid with 80% probability.

Turning on this feature, then playing openings against a large database, is a great way to learn or test your knowledge of your opening repertoire.
