pls tell me

what is the analysis feature in daily chess?

try using it

its not an analyzer which can tell u ur moves but u can only practise ur moves there

instead of calculating and imagining the moves, u can make it there, it works like the analysis in votechess

It's similar to having your own chess board next to you, where you can make moves and run variations on your own.

It gives you an advantage over someone that tries to calculate everything in their head, but it's not cheating, since it doesn't give you computer assistance (you're calculating everything on your own).

You are not permitted to use it in games

You can in Daily, not in Live.

Why i can't see my friend when playing?

you need to have membership ig

Thanks for the correction @Martin_Stahl
