Stockfish 17 - analyzes the game of grandmasters: Muzychuk, Anna - Paehtz, Elisabeth


Another game from the series "Stockfish 17 chess engine analyzes the grandmasters' game". This time it's a game of women who hold the title of grandmaster (GM) from the recently concluded FIDE Women's Grand Prix 2024/25 in Cyprus. Anna Muzychuk, who won the tournament, defeated Elisabeth Paehtz in the penultimate round. How did Stockfish evaluate the champion's game?
