As a Spaniard chess player, I think my country is overrated! I played online against many players with 1900 FIDE rating and they beat me most of the time, whereas 1900 FIDE rating here I managed to beat.
The Rating Revolution: A Forensic Audit of the Global Chess Economy
The book illustrates clearly how the current ELO-system can’t cope with the post-pandemic global booming of Chess and how the system no longer is an adequate expression of playing strenght on a mondial scale.
As a Welsh chess player, I think my country is overrated alongside the other 2 home nations (although for Wales' sake, the lack of players actively playing within the FIDE pool is another matter to make high anomalies), with the persistent use of the national rating system that leaves many players have completely different ratings compared to their FIDE equivalent, if they have any. By improving and expanding junior development programmes, moving away from the ECF rating system and switching to FIDE-only rated events, this ensures the UK is a productive chess nation with players' ratings a fair assessment of their strength.
Quite an interesting topic, especially since our modern era is experiencing a lot of innovation as with different time controls and even chess format themselves!
So it's clearly something worth paying attention to and exploring further
Kudos and good luck Vlad!
When I was still living in Egypt, I have won against 2100 rated players before and got crushed by 1000 rated players, I then started to realize that there is something wrong and I started to lose trust in the ELO system, with your analysis and maybe the intetion of serious corrective actions from FIDE , I believe it could be fixed, Well done Vlad!
Super interesting subject. I'm not sure about that title. I would suggest something more like "The Problem With FIDE Ratings". I know having a word like "revolution" in the title is often recommended, but in this particular case it would seem more accurate to describe it as the problems with it. "The Rating Revolution" to me makes it sound like it's a book about how ratings have changed chess from when there was no ratings, and maybe stuff about how the rating system works mathematically. It doesn't suggest you are appraising it (I understand the second part kind of goes that way, but I think the first headline title is most important).
But the content is definitely something to think about - might be especially eye-opening for people who think FIDE ratings are some infallible Gospel truth about chess strength while chess ratings online are just stupid, but of course as usual the people who should read something the most are probably among the least likely to!
With a Foreword by Levon Aronian, this new digital download by FIDE Arbiter Vlad Ghita (that's me!) discusses the causes that led to rampant rating deflation within FIDE. It answers 3 main questions:

1) Which countries are underrated and which ones are overrated?
2) By what mechanisms did we reach this point?
3) How can FIDE correct this going forward?
I am a physicist (like Arpad Elo!) at heart, but made a career conversion towards chess in 2021. Scroll through the free preview, maybe you'll like what you see.
