You will be familiar with the name of the famous chess player Gary Caspro, who ranked highest in FIDE history in 2849. You will also find that the Elo system calculates the power rating. But do you know how? The Elo system is named after Dr. Irpad Elo, who improved on the original developed by Kenneth Harkins. It has been in use in the United States since 1960 and was acquired by FIDE in 1970. This system is twofold: It shows how strong the player is: Player A rated 2400 Player B rated stronger than 2300.

2. It also calculates the results of a game, tournament or event as the results of a numerical assignment. Originally designed as a chess classification system, it is now used in many other games and computer games. Every Elo Idea Every chess player has a chance to win the game. The stronger the player, the greater the chances of winning. FIDE uses a special probability of winning table for a game based on the ranking difference between the two opponents. If the ranking difference between the two is 0, then each player has the same probability of winning, and their probability of winning is 050. If the difference is 100, the strongest player has a chance of winning 0.

64 while the weakest is 0. 36. Note 100, 0. 64, and 0. 36. Let’s imagine Player A has 2400 and Player B 2300 to officially play 100 games. The difference in score is 100, so the expected result for player A is 0. 64 and for player B 0. 36. And now the main idea … if Player A2400 and Player B2300 are really playing that hard, Player A64 and Player B36 will definitely score at the end of the event. If Player A gets only 55 (but expected 64) and Player B45 (more than expected 36), Elo System will change its new ranking. The system uses the K K element, which is essential for grade calculations. The K factor is assigned to the K factor player, and its possible FIDE values ??are 10, 15, and 25:

– 25 for new players on the leaderboard, unless they complete events with at least 30 games.

– 15 for players with a rating below 2400.

– 10 Once the player has reached 2400 and has enrolled in at least 30 games. After that, it remains at 10 permanently, even if the player’s rating is below 2400 at a later stage. Depending on the change in the rating of a game:

– Player K element.

– Athlete score (1, 0. 5 or 0)

– The expected result of a player for a game. Example 1. With a factor of 10, Player A defeated 2400 by 2400.

The change in rating for Player A is calculated as follows:

K factor x (result – expected result)

10 x (1 – 0. 64) = 10 x 0. 36 = 3. 6 Example 2. With a factor of 10, Player A lost from a rating of 2400 to a score of 2300 against Player B.

In this case, the rating change for Player A is calculated as follows:

K factor x (result – expected result)

10 x (0 – 0. 64) = 10 x (- 0.

64) = – 6. 4 Example 3. With a factor of 10, Player A has a rating of 2,400 and Player B has a rating of 2,300.

The change in rating for Player A is now calculated as follows:

K factor x (result – expected result)

10 x (0. 5 – 0. 64) = 10 x (- 0. 14) = – 1. 4 End A chess player’s new rating is calculated based on a change in rating. Updated, the FIDE ranking list is available online on January 1, April 1, July 1, and October 1.
