Gukesh vs Ding Liren is the most precise World Championship

Dr. Mehmet Ismail, the man behind the Complete Performance Rating (CPR) idea has published massive Stockfish analysis of all World Chess Championship matches 1886 – 2024. It has concluded that the World Chess Championship 2024 – Gukesh vs Ding Liren is the most accurate so far and that the accuracy generally increases over the years.

• Ding Liren vs Gukesh match is the most accurate one so far (least missed points)
• Excluding the ongoing match, Anand is the most accurate player
• Carlsen has the highest game intelligence score
• Figure illustrates a trend of decreasing missed points (increasing accuracy) over time.
• Initially, players averaged more than 1 missed points per game, meaning their mistakes added up to over one significant blunder per game. Over the years, average missed points have decreased significantly
• Increasing accuracy over the years is consistent with prior accuracy analyses and top GM opinion.
• However, this increase is not universal.
• José Raúl Capablanca, who is known as a generally accurate player, remained the most accurate player until Anatoly Karpov.
• Anand averaged 0.4 missed points per game. This is the highest accuracy in the dataset.
• However, Magnus Carlsen stands out with the highest game intelligence score of 161, which suggests that Carlsen’s playing style, while not always following the top engine move, tends to elicit more mistakes from his opponents compared to other players.

Dr. Mehmet Ismail concludes, “For each year, I calculated “average missed points” per game per player as in the picture. A value of 1.00 or 0.50 missed points corresponds to making a game-losing blunder in a winning or drawn position, respectively. 0 missed points mean perfect play. Missed points measures the points a player misses in a game according to Stockfish (depth 20). Each miss is calculated using the win-draw-loss probability of the top engine move and the actual move.”
