Sharing a premium account.

Heyy,

My brother bought premium membership, I believe diamond. So I was looking around on the forums and found a few threads about sharing an account. All of them said it wasnt allowed because of us having different ratings which would not be fair in matches.

I feel like part of the answers was missing though. Such as if i could use his account for:
- Non ranked matches
- Non ranked puzzles (like puzzle rush)
- Analyse games which I played
- The chess.com lessons
- Playing against the engine/bots

Let me know what I can or can not do.

Thanks,
Mart

The basic answer is that no, you should not share an account. If it's found that the account is shared, the site may close it
