Freeware by Peter Klausler. Windows 9*. CDB builds databases of chess games and positions and keeps track of all known moves in a position as well as game statistics. Games are added from the user interface or by importing PGN, text, NIC, ChessBase or Chess Assistant. Positions can be analysed with Crafty. CDB also works fine as a PGN-browser and is a useful tool for conversion from different database formats to PGN. Download : http://www.chessopolis.com/cdb-1_5.exe (398 KB).
