Playing in our leagues will allow you to play long serious games with opponents of all strengths and with frequent review/study times. We believe that this is a very good way to improve your go skills.
The Open Study Room is currently running 4 different leagues:
This league resets monthly and is the main OSR league.
Two players in this league may at most play 3 games against each other every month.
You can find more detailed rules of this league here.
This league resets every three months.
Joining another league will automatically enroll you for Meijin league. This way Meijin league also gather all OSR games.
Two players in this league may at most play 5 games against each other every month.
You can find more detailed rules of this Meijin league here.
The rules are the same as the OSR monthly ladder but only double digit kyu player will play in it.
The idea is to allow such player to find a competitive place to play long serious games.
We remind you DDK league players will automatically participate in the OSR ladder and OSR meijin leagues!
Monthly league for dan-level players. Maximum of 3 games between any 2 players. Dan league players will automatically participate in the OSR ladder and OSR meijin leagues!
It is recommended that you sign up for the league that is most appropriate for your strength at Go. You will be automatically added to the OSR ladder and OSR Meijin leagues if you sign up for either the OSR DDK or OSR Dan league.
Since a game can count for multiple leagues at the same time players usually participate in several leagues.
The following rules applied in all our leagues:
Players are strongly encourage to review the game afterward. If both player have the same rank, or if your opponent can't help you reviewing your game, one should feel free to ask stronger players in our KGS room and/or in our Discord channel help for the review.
If you played a game and missed one of such rules, an admin will be able to correct that easily.
If those rules are not clear to you, remember that OSR devoted team will always be happy to answer your questions.
