Play online chess |  Subject: GK rating vs FIDE rating
Message:
How does GK rating compare to FIDE rating?
2200 FIDE is nothing special, but here 2200 is in the top 100.

...is that this question has been canvassed before. The fact is that though the statstical system (ELO) is the same, and the numerical values measure relative (note that: 'relative') chess playing strengths, the two are not really comparable. They are actually measuring different things.
The FIDE system orders chess players who participate in international OTB (over-the-board) games under strict tournament rules.
GK measures those who play chess by internet on this particular site. The very fact that the systems were instituted at different times - roughly 30 years' difference - is alone sufficient to create a significant difference in the numbers you are looking at. I can think of all sorts of other reasons for such differences. Bear in mind, as I've said elsewhere, the rating number has no meaning in itself. I seriously doubt Professor Elo himself would say anything different. It is where your rating stands on the list that is significant, and the size of the difference between your rating and another's (even that should be taken 'cum grano salo'!). Of course, the whole thing is built on the ongoing history of all the game outcomes (W, D, L, and who played whom) since the rating system in question was instituted (FIDE in the 1960s, GK c.2000).
Personally, I have my doubts about the ELO system, about the claims made for it, the uses to which it is put, and the way it is interpreted. I'm pretty certain it isn't really robust enough mathematically to update one's rating game by game as it now does (the original FIDE system didn't). But as also has been said elsewhere, it's probably the best we can hope for.
Cheers,
Ion

Judit Polgar adds to legend by reaching last eight of World Cup — Judit Polgar added another glowing chapter to her living legend this week when the all-time No1 female chess player, now a 35-year-old mother of two, reached the last eight of the World Cup and knocked out the top seeded world No 5 Sergey Karjakin. Polgar has competed little in recent years due to her family commitments, but she outprepared and outgeneralled the 21-year-old Russian, who set out his stall for a draw by choosing the ultra-solid Berlin Wall. Polgar was ready, and subtly weakened Black's defences. After Karjakin missed the best defence 21...Rh6! she found 24 Nc3!, netted a pawn, then converted it to a won ending ...
