Yes, you can use it on Ubuntu, as a is a Java application (Java-8), and that means that is cross-platform ... you must only have JRE installed.
The features of the application. You can:
- Open PDF books and extract its games (in algebraic notation).
* Extract standard tags of the game (Name of players, ELOs, Location, Opening code, ...)
* Extract game variants
* If the game does not start from standard starting position it tries to act as an OCR extracting the FEN string for that position from the image at PDF.
- Open and save games in pgn format.
- Edit variants (add or remove variants, or continue with the following move)
- Connect to UCI engines like stockfish, although you have to configure the ones you download (there are no engines installed by default).
- With those engines, you can:
* Analyze positions
* Analyze full games
* Play a timed game against a Uci engine (some of them allow you to choose the strength), or play to another player, or make two engines play eachother.
There is also a command line version of the games extractor, so that you can invoke it from a script, or automatize the extraction of many chess books (but you have to program that script)
jdk works?
Hello Made_in_Shoreditch,
the application tries to extract variants of games, as well as the standard tags (Player names, ELOs, and so on), but with some limitations, it does best effort. There is a user handbook where all details are explained (although I will be pleased to answer all questions you make)
It does not try to extract comments, because, although I am not a loyer, I think it would not be legal. So annotations are not added to the extraction, but the application gives you the possibility to add those annotations (open the menu option: Windows -> Edit comment window). You can copy the comments you are interested on at each move (do not forget to accept changes before changing the position!)
