3.5.17.2 Can Let’s Check be used anonymously?
Let's Check can be used without logging into a Playchess.com account.
In this case you will receive no information about who analysed which position.
3.5.17.3 What does it cost?

displayed in the Chat window.
3.5.17.5 What engines are allowed?
Every engine that can be used in the User interface can be used for Let's Check.
