ChessX is a free chess database and PGN viewer for Windows.

ChessX allows you to load and save PGN files and work with multiple databases simultaneously.

You can browse chess games, including variations, enter moves, variations, comments, board setup, copy/paste FEN, search in Databases for text or positions, display tree of moves for the current position, and analyze using UCI and Winboard/Xboard Chess engines.

Finally, you can also prepare for openings or opponents, and use the training mode. It also features the integrated Stockfish engine and FICS Support.

We kept both the new 64 Bit version (1.4.11) as well as the old 32 Bit version (1.4.6) zipped together for your convenience.
