show book

If I'm playing a live game and I select the "show book" option what does it do? I don't want to do it because I don't want to use a suggestion during a rated game but I'm not really sure that's what it does because that would be cheating. does anyone know what happens when that option is selected?

I meant in "daily chess"


It shows you continuations of master games from the same position. It's allowed on Daily games, though the fact that the app lets you go deeper than the website has always confused me (guess it's a tradeoff for using the app without other features tongue.png)


Its prefectly legal to use that book in your daily games. But not live.
