File Format Notes:

• CBV type files are Chessbase archive databases. They can be opened with Fritz, ChessBase, ChessBase Light, ChessBase Reader, and Chess Assistant. If you don't have one of these chess programs, you can go to www.chessbase.com and download the free ChessBase Light.

• PGN (Portable Game Notation) type files can be opened with almost any chess program, and also any text editor such as MS-Word or Notepad.

• As of Nov. 10, 2017, we have replaced MyChessViewer with the more modern ChessBase viewer. You can view games in the PGN files directly in your browser, and perform other functions such as running a chess engine to analyze the games. (Engine not available for all browsers; Google Chrome is recommended.)
