On-line Chess - Part 1.10 - Game archive and statistics

A good player takes note of the move list of his/her games in order to analyze later and improve from mistakes. No piece of paper is required when you play on-line chess because the system takes note of the game moves and save the game in the Portable Game Notation format in a database. That’s really useful. Database access makes it easy to query for a match against an opponent or for a game played years ago. You can then review the game using your client program or download the PGN file and open it using your favorite computer chess program in order to let it analyze deeply the game and find the mistakes and good moves. Game archive has a cost for providers of the gaming service (disk space is not for free), for this reason usually if you want to store all your games you have to pay while free subscription have limited storage size.

Another possibility is to upload games in PGN format on the database. Even if they are not played using the provider service, this is a way to collect the games you want on the net so they become available everywhere an internet connection is available.
Statistics are another interesting feature. In the basic form statistics report the number of games played, won, drawn and lost. Advanced forms could report your rating evolution over time or the statistics on openings used in your games and several ways to present the data graphically. Any means to show you how strong you are is appreciated.
