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.)

Additional File Format Notes from Drayton:

• The ChessBase (cbv) files have the best annotations and I recommend that everyone should get ChessBase on their computer. There are two free versions of ChessBase (CB Light and CB Reader) available with limited features.

• When I convert the ChessBase file to PGN it loses several features: 1) all medals and colored arrows and squares; 2) Diagrams will say "Diagram" in the text but it doesn't print real diagrams anymore, even if you convert it back to ChessBase. 3) Chess symbols & fonts such as "+/=" are not readable unless you open the PGN file with ChessBase on a windows computer.

2006 notes: There is no commentary in the PGN files because some chess programs have compatibility issues with annotated games. The "Update" version of both files contains 10 additional games and corrected games as follows: 1) Additional games that were published in Northwest Chess magazine. 2) Updated commentary of some games that were published in Northwest Chess. 3) Correction of moves to Inglis-Woodlief game. The complete version also contains corrected player names (Ignacio Perez and Dennis McGuire).
