The table starts with beginners and ends with amateur experts.

Disclaimer

Although it is stated above, this does perhaps bear repeating: this table is at best approximate, personal counterexamples abound (see /discussion) and rightly so. The national ranks are arguably likely to be more comparable - they are computed on the grounds of games of a standardised nature, with players in broadly comparable environs; this is markedly not the case on the servers. Where one AGA 4 kyu may play online in an internet cafe, another might have his/her kids running around, the TV on and dinner burning on the stove as they play, or anywhere else for that matter. Perhaps this table should simply remind us:

  1. Ranks are a great advantage of go in allowing decent games between players of different strengths but that is all, and they can become a great distraction
  2. Don't take absolute ranks too seriously.
  3. Be prepared to judge handicaps more by the evidence of games and less what the ranks say.

Rating Methods


More Ratings Links

  • A European 7D grade is believed to be approx equivalent to a professional 1D grade.
  • Is the below DGS "convert" link now dead? Should it be removed?
    • For rank translations between AGA, China, Europe, Japan, Korea, IGS, DGS and IYT see function "convert_to_rating()" in [ext] DGS server source code. ErikO: The conversions in "convert_to_rating()" are in most cases taken directly from the rank translation table at NNGS (type help rank).
  • GoFederation?: You may find your real EGF rank after solving this test:
              [ext] http://play.baduk.org/

A test for "the real EGF" will only foster another table:

       EGF (age)         | KGS   | IGS   | Dinerchtein test
       ----------------- | ----- | ----- | -----------
       5 kyu (3 months)  | 2 kyu | n/a   | 4 dan
       11 kyu (3 months) | 7 kyu | n/a   | 3 kyu
       n/a               | 1 kyu | n/a   | 4 dan
       n/a               | n/a   | 5 kyu | 3 dan
       n/a               | n/a   | 11kyu | 1 dan?!
       1 kyu (1 month)   | 1 dan | n/a   | 4 kyu

An ego booster. :) (Nicks/names left out to discourage any bragging-factor. "Age" is time since last tournament.)

unkx80: I tried it too. Was told that I am European 5 dan. Like, wow, so overrated. The biggest problem is that it is MCQ. If it is not MCQ I might never thought of some of the choices.

Anyway, I hope that he releases his answers (together with the reasoning) later so that it can be valuable study material.

Phelan: I've already posted this at the CoffeeMachine, but thought this was an appropriate place as well: I saw a post on rec.games.go which I assume was by breakfast, saying that he will explain the test problems in [ext] http://play.baduk.org/, this sunday, Jan 28 at 6pm GMT (21.00 Moscow time) on KGS (English Game Room).


Reflame I think there is an easy way to fix the differences among ratins systems - why do associations not do it this way?
