Make sure you download the right version. To open the pgn file Modern Database to see the chess games in it, you need a chess database like “SCID vs PC” (free, see this page below), or, for example, ChessBase Mega Package or as alternative the Russian database Chess Assistant PRO with Houdini PRO (DVD) or the interface of a commercially available chess program like Fritz Chess Software that has a chess database included to which you can add my Modern Database. This means you just extend this pgn database over time and add more games to it. You can use my pgn chess database with “SCID vs PC” and build your personal chess database with it. If download does not work then send me an email and I send you the download link. I have to charge you $35 for the pgn downloads, because it has been a lot of work to build the pgn file (expertchess.zip) with over 540 000 chess games, as you can surely imagine. However in the beginning SCID seems to be complicated to use it, so I will explain some important features that you must know to be able to build your database. You can also run chess engines and play games against the computer. With “SCID vs PC” you can create huge chess databases without having to buy expensive chess database software. Shane’s Chess Information Database (SCID) was originally written by Shane Hudson, but has received strong contribution from others. I have collected over 540 000 tournament chess games (pgn downloads) from five years for you (till June 2016) and I show you how to build your personal chess database using a free database software program called “SCID vs PC” (free).
