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(EST, Eastern Standard Time, GMT -5). A day after, at 18:45, the Yunguseng teacher will review 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.
We'll meet one weekend each month to play one more round. The schedule is detailed further down in the Google Calendar.

  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, and Thursday evenings at 20:00 ET(GMT -5, after daylight saving time GMT -4).
And once a month, there will be a game/review on the weekend.
If a member can't make regular time for the scheduled time or wants to change the game date or time, they can use a 'contact list' to contact their opponent to reschedule.
The 'Contact list' is shared at the beginning of each cycle.

5. Reviews

From the 39th season, the teacher will review games one day after the games are played. It will be at 18:45 ET.
Members 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.'
It may also take some time to complete. 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://ayd.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

All standard members will take the Yunguseng rating point after their first joining.
As most of the members have a KGS rating, there's a table on how the KGS rating will be converted to a Yunguseng rating.

Please see the KGS - YD rating conversion table:

*  YDR = Yunguseng Dojang Rating

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 point of 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, 1 point per game will be given as the game experience point.
It means that winners get 1 Rating point more and the losers 1 less, so it's +11 and -9 if two equally strong players meet.

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 a lack of slots. 

As a spectator, you can participate in the following:
1. Join ongoing reviews & lectures
2. Watch all the recorded videos for the past seasons

* If there are more than 150 times of hits for watching lectures in less than 10 days, 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; the teacher gives his opinion of each member's style of play, strong & 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(three months) as a league player. The second report is in the third season(two-season term), and from the third 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)
