Yunguseng league system

We play the game on KGS in the 'Yunguseng Dojang' private room. The games are played one evening per week at 20:00(Central European Time, GMT +1 in General, with summertime, GMT +2). At 22:00, our teacher joins the room and reviews three or four of the played games. The games the teacher couldn't review online will be reviewed and recorded offline and put on the Vimeo video platform later. The "live" reviews are also recorded and can be watched again later.
One weekend each month, we'll meet to play one more round. You can find more details about the schedule further down in the Google calendar.

1. League system

Yunguseng consists of 15 leagues and 6 players in each league.
After each month, 2 people will go up, 2 people stay, and 2 people will go down.
Each season, the leagues are set according to participants' rating points. 
Therefore, there's no connection between seasons.
(Ex: Someone made a promotion to league C2 from C3 at the last cycle of the season, but it doesn't give a guarantee to join league C2 in the next season because the new season will completely reset according to new members' rating points)
*Best player reward: The 1st place of the league A1 will get a month-free reward. It's for bringing more strong players into the Yunguseng Dojang and also making their games more competitive.
At the same time, we strengthen the Anti-cheating system. Please check the Rules page for more details.

A full league system will be played; everyone plays everyone else in their league(Round Robin) once per month.

  1. Each player plays 5 games per month.
  2. The pairings follow a simple scheme
Game #1: 1 vs 6 2 vs 5 3 vs 4
Game #2: 1 vs 5 2 vs 4 3 vs 6
Game #3: 1 vs 4 2 vs 3 5 vs 6
Game #4: 1 vs 3 4 vs 5 2 vs 6
Game #5: 1 vs 2 3 vs 5 4 vs 6

4. Playing days & times

The games will be played on Tuesday, Wednesday, Thursday, and Friday evenings at 20:00.
* In case people can't make time on the original date, it may change by personal negotiation and admin's help.
At 22:00, the teacher joins the room and reviews three or four of the played games. This will last until 23:00 -23:30.
Once a month, there will be a game/review on the weekend.

5. Reviews

Participants can join and watch all the group's games and reviews. You can also watch all the recorded lesson videos.
There will be 9 games in each group(3 leagues), and about 5-7 games will be covered by online reviews. The rest will be reviewed in an offline format review video called 'Additional review.'
And it may take some time to be done. In general, it takes 3-4 days after the game time. But it may take a week in the busy period(end of each league).

6. Lectures

The Yunguseng teacher will give 3 lectures per month. The lessons are on KGS [Yunguseng Dojang] room.
Since the 25th season, we have used Discord for better-quality audio. Please follow the Instruction video: https://eyd.yunguseng.com/videos/index.php?id=4451
And the [Yunguseng Dojang] Discord channel: https://discord.gg/hJvRaa7

We will record these lessons. If you can not manage to be at the online lecture, you can watch them later.

8. Yunguseng rating

Initial rating will be given by this priority:
1. 1:1 conversion the E.G.D(European Go Database) rating to Yunguseng Rating.
2. If there's no E.G.D rating, then we give a rating that is based on the KGS rating. And here's the rating conversion table: Yunguseng rating conversion table

The rating system is very simple. If two players of the same strength play each other, the winner will get 10 rating points, and the loser will lose 10 points. If the players are not evenly matched, the stronger one will receive one less rating point for every 50 rating points difference between the players.
For example, if a player with 100 more rating points wins, they will only gain 8 points (and the loser will only lose 8 points).
This continues until a player is 500 points or stronger than the other, then the stronger player wins 0 rating points. But if they lose against a player 500 points weaker, they'll lose the maximum possible rating points 20.

Yunguseng Rating
Difference weaker stronger
  W L W L
500 +20 -0 +0 -20
450 +19 -1 +1 -19
400 +18 -2 +2 -18
350 +17 -3 +3 -17
300 +16 -4 +4 -16
250 +15 -5 +5 -15
200 +14 -6 +6 -14
150 +13 -7 +7 -13
100 +12 -8 +8 -12
50 +11 -9 +9 -11
0 +10 -10 +10 -10

* Since Season 20, January 2018, in Every single game, players take +1 point as an 'experience' point. 
So if two equally strong players meet, the winner gets +11 instead of +10 and -9 instead of -10 for players who lost.

Rating reset:

1. If a member has more than 120 rating points gap between the E.G.D rating point and YD rating point, they can apply the rating reset.
   (ex: YD rating 1100 / EGD rating is 1300) 
2. Then, 50% of the rating points difference will be given. 
   (ex: YD rating 1100 / EGD rating 1300, = 200 points difference. So take 50% of the difference of 100 points to get a new rating of 1200.)
3. If old members return after more than two seasons of a break, they can apply the rating reset and take 75% of their rating points difference. 
   To apply the rating reset, the rating difference should be more than 120 points.
   (ex: Stop at YD rating 1500 / return with 1900 rating point = 400 points difference, so take 300 more points to get 1800 rating point)
4. If old members return after more than two years of a break, they can apply the rating reset completely.
    This means that they can import their E.G.D rating points to the YD Rating.

5. It's possible to apply the rating reset each season.
6. To apply the rating reset, there should be more than 150 points from the initial rating points.
   (ex: Take 2000 initial rating points, lost 200 points in YD league(1800 points), EGD is still 2000. Then it's impossible to apply the rating reset. 
    But if the EGD rating is 2150, which is more than 150 point between YD initial rating points and EGD rating points, it's possible to apply) 

9. Spectators

The spectator package is meant for those people who want to join the reviews and lectures but don't have enough time to play the league games or can't join the league due to lack of space.
As a spectator, you can participate in the following:
1. Join ongoing reviews & lectures
2. Watch all the recorded videos for the past seasons(Lecture library)

* If there are more than 50 times of hits for watching lectures in a day, 150 hits in a week, and 350 in a month, it can be treated as collecting lecture videos, and the membership can be stopped.

10. Personal report

It's a personal Go report in which the teacher gives his opinion of each member's style of play, strong points, weak points, and where to focus on studying Go. Including the teacher's comment, you will understand more about your Go, and it can be a map for making your study plan.
It'll be given to all members who complete one season(3 months) as a league player. And then 2nd report at the 3rd season(two-season term), and from the 3rd report, it will be given every year(three-season term).
(Ex: After 1st season: 1st report: / After 3rd season: 2nd report. From the 2nd report, each three-season(one year) term, the new edition will be given)
