The Elo system is based on steps of 200 points each in chess, through which the players with the Elo number are qualitatively divided. The probability that a beginner wins against a grandmaster is almost zero percent.

Chess beginners and grandmasters
In professional tournaments, the Elo classes are now divided into steps of 25 points. Players with the same Elo rating generally have the same high expectation values in chess. It must also be borne in mind that the Elo system in chess is subject to constant inflation, as game theory is constantly being developed. The strength of 1500 Elo points from 1945 corresponds to a strength of almost 2000 Elo points today.

The grand master
With this categorical subdivision, however, it must be noted that, for example, the title of Grand Master is not automatically awarded. This is linked to a number of requirements and defined standards. The subdivision shown here also relates to men. For women, values are created that are 200 Elo points lower than those for men.
Some facts about the Elo number in chess:
The general Elo distribution in the population corresponds to the mathematical normal distribution according to Gauss. The scope of an Elo class is exactly 200 points. The profit expectation for the stronger of the two players is exactly 75 percent. If, for example, the fictional player A has an Elo of 2000 and plays a game against the fictitious player B, then his expectation of profit is exactly 75 percent. With a point difference of 400 Elo points, the profit expectation for the stronger player is already 94 percent. With a difference of 600 points, the victory of the weaker player is statistically almost impossible. Click here for the Elo calculator Chess Bundesliga .
