Lichess also has conditional pre-moves in correspondence chess
thanks, didn't realize that was in there (I only use lichess on my phone though...)
For a long time, conditional premoves in correspondence didn't exist on the mobile app, only on the site - but that's fixed now too.
You can premove as many moves as you want in a lichess correspondence game. I feel like you can even premove to whatever depth you want, but it has been a while since I've played.
That's a different feature, but sounds cool! Didn't know about that.
