If you didn't play for very long time, your rating will reset like when you first time playing chess games.

The rating system changed so that 1400 is now the lowest performance that will provide published ratings and as part of that, there were rating increases and changes to the initial rating formula.
1. A one-off change to Standard Ratings for rated players: For players with a standard rating lower than 2000 points, an increase will be applied following the formula (0.40) x (2000 – Rating). Players with a standard rating of 2000 or more will retain their current rating.
2. Changes in the rating floor: An increase in the rating floor from 1000 to 1400.


FIDE has made multiple changes over the years. It used to be that if you didn't reach a 2000 performance, you didn't get a rating at all. I don't recall what the first decrease was but know that later it went down to 1000.

It will be interesting to see how it plays out and whether those that received boosted ratings end up dropping back towards where they were initially in a year or two.


Same happened with me. I noticed it yesterday. It went from 1428 to 1657 for no reason. I haven't played at a rated tournament in the last month.

I think more likely scenario is these boosted ratings will hold up and higher ratings will inflate, because they will get more points for beating same strength players (unless that changes as well)

Tht's wht my previos rtg was 1230 but now it's 1536
Even though I didn’t play any FIDE rated tournaments within the span of April 1 2024 to April 5 2024
I was reading and apparently there is a new FIDE rating system effective from today is that why or is it some glitch?
