I am looking for a way to use Stockfish for an automated analysis of games which I have in pgn format. Similar to Fritz/Chessbase's Blunder Check function I would like Stockfish (or any other UCI engine) to "simply" go through each position of each game in the pgn-file (convert to FENs?), let Stockfish run for a fixed amount of seconds and then return the evaluation and depth reached. Maybe later I would like to add things like node count or the eval in each depth reached. Finally, the program should format the output to a human readable format.

Maybe there is a similar program already out there which I could use as a template but if not what would be the easiest way to get started. I have limited programming skills in Python and VB.

  • "I would like Stockfish... to "simply" go through each position of each game in the pgn-file..., let Stockfish run for a fixed amount of seconds and then return the evaluation and depth reached" - There are already programs which do this much. Did you want to program your own, or would you be happy with just this?

  • I would like to add custom elements like node count and evals at different depths - all info that SF returns. If there is an open source program that does some parts then I could add those features perhaps. But please let me know any programs that can do it. I only know of Chessbase and Aquarium.

  • Reading your question makes me wonder - you are already using Fritz/Chessbase and for some reason don't like those products - or you know they can do it but you don't want to pay and ask someone to make it for free? Because obviously you can do what you ask for 100% using Chessbase 15... not sure about other versions and Fritz interface - possible that it would work too - someone else could confirm

  • @Drako Are you saying that if I give to CB15 for instance a PGN with 1000 FENs representing 1000 positions, there's a way to tell CB15 to output (with a chosen engine, let's say our default kibitzer) somewhere (in the PGN, by completing it, or somewhere else) the list of evaluations (how to parametrize them ?) of these positions ?

    Stockfish can analyze a PGN file easily. Why isn't that enough?

There is a library for Python (import chess.engine) that allows you to use an engine (like Stockfish) to analyse games in a PGN file.
