Pocket Chess Database is a program for Pocket PC to help you find the games you are looking for in a pgn (Portable Game Notation) file. It does this by importing Tag information from the pgn file into an SQLite database, and uses it to create summary tables and statistics, giving a good overview of the file's contents. The games list can then be easily filtered as the user wishes, and the filtered games can be exported or their moves viewed in text format. One advantage of this approach is that it is possible to search large databases (e.g. more than 100,000 games) reasonably quickly, using a minimum of RAM.

Please note...

This isn't a program for playing a game against; nor can you replay games on a graphical board within the program. However, it is easy to export games from the games list into another pgn file, where they can be replayed using another program, such as CEboard, or PocketGrandmaster, or ChessGenius.
