Since 1996 there is an official rating for all swiss players
Guidelines for Swiss Rating and Ranking
Below 5 Kyu all players are free to set their rank as they feel it is right. For example
a 20 Kyu who has improved substantially can move his rank to 15 Kyu or even to 10 Kyu at once.
Of course a player should check himself if he has balanced games with players of the same rank
or according to the handicap stones against stronger players.
From 5 Kyu and stronger there are restrictions in moving up. A player can not jump more
than one rank between tournaments. The reason is that the official rating is reset if a
player jumps more than one rank. The guideline for ranking up should be the rating points
from the European Rating List. A player who doesn't reach the necessary rating points for a
higher rank should not claim a higher rank until he has reached the necessary points.
Here the Rating - Rank table
2500 +/-50 = 5Dan
2400 +/-50 = 4Dan
2300 +/-50 = 3Dan
2200 +/-50 = 2Dan
2100 +/-50 = 1Dan
2000 +/-50 = 1kyu
1900 +/-50 = 2kyu
1800 +/-50 = 3kyu
1700 +/-50 = 4kyu
1600 +/-50 = 5kyu
Moving down? If a player has constantly bad results in tournaments an his rating
points drop more then 100 points below the minimum he should rank himself down,
e.g. a 1 dan that drops below 1950 GoR should play as 1 Kyu or even 2 Kyu again.
Exceptions: A player that has improved very quickly can be ranked through a strong
Swiss player preferably a boardmember of the Swiss Go Association.
In Short:
You want to move up faster in ranks because of whatever reason!? Then it is your duty
to get an approval of a strong swiss go player and inform the organizer of the next tournament
about it.
