PGN Viewer

Can I use chess.com free pgn viewer offline to study games or do I need to purchase the software? Is it only for the content on chess,com? Is stockfish also a pgn viewer, fritz or chess base? How do I develop a library of games of my own as well as someone else's for study?

PGN viewer

1. you cant

2. no, you can upload your PGN to the analysis board

3. no stockfish, yes fritz, yes chessbase

4. chessbase (assuming you already have it, see #3)

Okay Thanks. mgx960. So I need to get both Fritz and Chessbase then correct or just 1 of them?. I was using the free pgn viewer from chess.com then all of a sudden it quit working. It happened when I tried to delete some games out on my computer. 

There are a number of freeware PGN viewers: ChessPad, ChessX, Scid vs. PC, Scid, etc.

cool thanks for the info awesome

Thanks for the information here. Also wondered about those and similar questions.... A free chess software for desktop that can view PGNs was what I was wanting for some time.
