Question: Which format do my games have to be in ( PGN or CBH ) to upload them to the ChessBase cloud?

 

The ChessBase-cloud is a feature were you need either ChessBase or a ChessBase-account.

 

If you use ChessBase, you may create a Cloud-database and then your able to enter games by replay them move by move, or just copy and paste them from other ChessBase-databases, either PGN or CBH.

 

If you use the ChessBase-account exclusively you are able to open in the Web-App “My Games” PGN-files which are stored on your local disc.

 

You are able to copy this game in cloud-databases which you have created with the Web-App.
