Step 2 - Making the WCH database work under Chessbase

The easiest way is to locate the file on your HDD  where you downloaded it and double click on the file. (picture 2 below) Or if you prefer to go to ChessBase first, then go to File > Open > Open Database or directly find the file via left-hand explorer panel in CB. This will pull up database onto your workspace (right panel) from where you can navigate and analyze the games, making trees, create reports and so on. (for detailed tutorials on ChessBase, please refer to a separate section)

Step 3 -Extracting the .cbv file on a workspace and making a 'reference database'

Once you are on the Chessbase double click on the added icon and wait few minutes until the .cbv file fully extracts itself (see picture3). Once this is done, the last step before we are finished is making the database as ''reference database''. This means for all analyses of openings, games, reports, trees, Chessbase will use Wind Chess DB as chess ''default knowledge base''. (picture 4). Installing is done, we should see WCH on your workspace. (picture 5)
