User Rank?



I am new here. I notice most people have a k like 1-25k or d like 1-9 d by their name. Is that kyu or dan?



Yes. It’s kyu and dan.

It’s their rank on OGS.


Furthermore you will find people talking on sdk (single digit kyu) and ddk (double digit kyu) but no ddd because they are hard to find! (and so no sdd)


Everything important (Kyu, DDK, SDK, Dan), has been said here already, so let me note two somewhat esoteric acronyms:

  • TPK – twenty-plus kyu, usually used for total beginners
  • TDK – triple-digit kyu, doesn’t really exist but sometimes I think I actually am TDK, namely when I play really dumb moves :laughing:
