Installing CQL

  1. Unzip the file This will create a directory named \cql in the directory from which was unzipped.
  2. Convert Heijden's ChessBase endgame study database (or whichever database you want to search through) to PGN format.

          To do this:

  • Create a new database named heijden.pgn in chessbase with a format of PGN.
  • Drag the icon for the Study Database onto the icon of the new database.
  • Move heijden.pgn into the \cql directory.



This completes the installation.

You can now run CQL.
