I don't think one person could complete the project - and stay mentally stable! But I suspect many of us have already converted the openings we play/study from NCO into Chessbase (or whatever software you use). In terms of resources, it could be done using some sort of Wiki-type page or even GitHub.
I was thinking that maybe we could set up an online project where people submit the openings from NCO that they have inputted into their computer? For example, if you have saved the moves from the Scandinavian (Introduction) page 124 then you could upload that file and it would get added to the full database. What do you guys think? Any ideas or appetite? I'm working on one now, but it's a few years away from finishing. When I watch a chess tutorial on YT where they analyze some grand master game, they go through the first ten to fifteen moves very quickly and say thats all. But not even some pgn file? I mean there are three million chess books, but no one had the idea to put together a pgn file with the most important openings and its main variations? You can analyze your positions and games online with a powerful chess engine - Stockfish. You can import your game in PGN notation or set up a position from a FEN.
First I thought lets download some app where all the openings are explained. Reproduce and analyze your games or the positions you want.
PGN is the usual format to distribute chess games through the Internet and I suppose that most of you are familiar with it. This change became necessary in order to improve the usability on mobile devices.
Parse a game, saving the comments as hash of list (see. Chess::PGN::Parse does not directly support recursive parsing of games, but it makes it possible. Please be patient! Remark that I switched to the new ChessBase reader and the result page opens a new browser tab now. One of the things you can do with these sequences is to parse them again and get bare moves that you can feed to a chess engine or a move analyzer (Chess::PGN::EPD by H.S.Myers is one of them). But even with a few hundred games there may be some seconds delay. This covers most of the game databases offered for download throughout the Internet. In order to avoid heavy server load and client-side busy script errors, file size is restricted to 10 MB. If you were searching for a web chess replay for your own blog, look here! If you would like to replay chess games anyway, you can post or upload them here provided that the game(s) are in PGN format.
On public computers in libraries, Internet cafés, youth hostels and so on it is usually not possible to install a chess game viewer like ChessBase, Chess Assistant or SCID.
