Chess Study Assistant

Chess Stats uses Stockfish 17.1 to analyze any game in a pgn file. It then saves analysis and shows statistics for blunders and best moves for every move of the game. Interactive chessboard shows continuations from any selected move. From the interactive board you can step through the continuation or make new moves with the mouse. New moves calculate new possibilities.
