Scid (Shane's Chess Information Database) is a chess database application that includes many search and database maintenance features.
Scid provides everything you need to maintain chess game databases. You can also edit games, perform searches, import PGN file data, export games to HTML, PGN, or LaTeX files, and add comments where needed for reference. There is a lot to take in with Scid, and the UI reflects it as it is slightly cluttered. There is extensive documentation to help you get comfortable. Not only does it provide valuable info about tournaments, players, etc., but it also allows you to play against various engines, people on the Internet (FICS), as well as by correspondence.
Scid is for chess lovers who want to continue on the never-ending road to mastery.
