I am new here and I don’t quite understand how the “Accept/Can’t accept” option in the “Games” page works.
When I go to that page, almost all the games are always greyed out for me, and if I hover over the “Can’t accept” button, it usually says that I can’t accept the game because it is rated and the rank difference is more than 9. However, I get that feedback even with players ranked very close to me (in the 20s, say).
When I look at my profile page I see a whole point matrix and no ranks for the various category (blitz/normal/long//9x9/13x13//19x19)
I’m confused. How is the system supposed to work? For instance, if a 20K player (say) offers a long 13x13 rated game (say), how does the system decide if I am allowed to accept or not? By looking at my overall rank (which right now is 19K, so I should be able to accept)? or by looking at the matrix, extracting my 13x13 long score 1425 ± 239 right now), converting it to a kyu rank (is so how?) and then deciding if the difference is less than 9?
Is this explained anywhere already?
