Analyzing the loss of accuracy of An Jaehyeok by year
A sentipawns is a unit of measurement used in chess to represent an advantage. A sentipawns is equal to 1/100 of the value of a pawn. 100 sentipawns are equal to 1 pawn. These values play no role in the game, but are useful in computer chess and for computer analysis when evaluating positions. To evaluate the accuracy of play in a particular game, it is important to analyze the loss of accuracy of play (loss of sentipawns). For example, if a chess player, who played with white pieces, in a game of 30 moves made all moves on the first line (did not lose sentipawns), then his accuracy loss index will be equal to zero (just an excellent and almost impossible result). And if his partner, who played with black pieces, made 20 moves out of 30 on the first line, and 10 out of 30 moves with a loss of 100 sentipawns each time (for example, on the first line the evaluation of the position is equal to: +0.5, and Black made bad moves with an evaluation of +1.5). The analytical report shows the change in the accuracy of Jaehyeok in the opening and at the end of the game by year. The games were analyzed using the Stockfish 17.| Year | White Debute | White Endgame | Black Debute | Black Endgame |
