OGS team league proposal

Can we get two more people for the league?

Then I’ll consider sealing applications for the first round and we’ll play with four teams of three, or else with three teams of four depending on what looks best.

Otherwise we’ll either try the ten-configuration or I’ll give my place to BattlePrez and we’ll play with nine, in three teams of three.

If we stay at 10 people, I volunteer to observe the first matches.

seequ (2k) suggested he’d play if we made the format one round / month.

That’d yield us a table something like this:

Board Team 1 Team 2 Team 3 Team 4 Handicap?
First terrific 4d Martin 4d drifterwolf 1k Samraku 2k T1, 2 → T3, 4 (2H)
Second bugcat 3k (1) seequ 2k bswan 5k jiveo 6k T1 → T3, 4 (1H); T2 → T3 (1H); T2–T4 (2H)
Third Gia 21k Jakob 8k BattlePrez 8k bugcat 3k (2) T4 → T2, 3 (2H); T4 → T1 (9H); T2, 3 → T1 (6H)

One more player would still be awesome, though.

I would not play if one round per month. two weeks max.

Really hate those tournaments that drag on for years.


If you need an extra player (3k) I can join.


I think it’s time to hold a timing poll, since we now have twelve potential players, and I don’t think we want more than that for the first round (apart from reserves).

I’d like to define the format so that, if necessary, we can choose replacements if it’s inconvenient.

Please allow me to call everyone over:

Two weeks is the preferred time of 50% of the respondents and the reasonable time of 70%.

In comparison, three weeks polled 40% / 70% and one week polled 0% / 70%.

With that in mind, I’d suggest that players who find a two-week round intolerable drop out.


I’ve heard from Arclaw (15k) that she’d like to play.

We can expect that seequ (who hasn’t responded to the poll) won’t want to play the two week / round time control, based on comments he made to me on discord:

ah too much for me then

just too many games

We can replace him with Arclaw.

Here’s a four-team table. I’ve had the idea of adding players with their ranks descending in a simple boustrophedon order: left to right, down, right to left, down, left to right etc.

This ensures that all teams are both giving and taking handicap on at least one board, rather than one team doing only taking and another only giving.

I suggest handicap at half a stone per rank rounding down, ie. “H = floor(ΔR / 2)”.

Is there a mathematical sign for rounding down?

Board Team 1 Team 2 Team 3 Team 4 Handicap
1 terrific 5d Martin 4d drifterwolf 1k Samraku 2k T1, 2 → 3, 4 2H
2 jiveo 6k bswan 5k bugcat 3k jlt 3k T3, 4 → T1, 2 1H
3 BattlePrez 8k Jakob 8k Arclaw 15k Gia 21k T1, 2 → 3 3H T1, 2 → 4 6H T3 → 4 3H

Alternatively, we could still play as a three-team league if that’s preferred.


Board Team 1 Team 2 Team 3 Handicap
1 terrific 5d Martin 4d drifterwolf 1k T1 , 2 → 3 2H
2 bugcat 3k jlt 3k Samraku 2k N
3 bswan 5k jiveo 6k BattlePrez 8k T1 → 3 1H
4 Gia 21k Arclaw 15k Jakob 8k T3 → 2 3H T1 → 4 6H T3 → 3H

I’d rather play as a four-team league, because I don’t think it’s fair to put Jakob on fourth board if there isn’t another SDK there. We also each get an extra game that way.

Opinions welcome as always!


So you mean H = ⌊ ΔR / 2 ⌋

I prefer 4 teams.


Yes, bracket-style symbols with low extentions for rounding down ⌊X⌋
… and high extentions for rounding up: ⌈X⌉

I copied the symbols from this wikipedia article, but I have to say that in real life, I feel like the horizontal lines are usually made smaller.

Reminds me of 「oriental quotation marks」.


Just one or two more polls, then I’ll take the league to the next stage.

Once players and format are decided, I’ll move discussion to an OGS Team League discussion thread.

May I suggest to build the teams in a way to minimize the average level difference between them?

I can’t really understand your suggestion unless you make a table.

I’d certainly be interested to see an alternative system.

I voted 30 minutes, but for this particular one I think I’ll need the 60 minutes thinking time…
I’m ok with any main time, but not too much byo-yomi.

I voted, but any of the proposed time settings is fine for me.

I mean that in the 3 teams scheme il looks well rounded but in the 4 teams, I would rather associate the lowest k with the highest dans.

Could you make a table, though?

It’s all very well to speak generally, but a diagram has to be made to demonstrate which players are on which board and how that affects the handicap.

I’m open to your idea but can you give me something empirical?

What about getting the geometric means of the ratings as close as possible?

Would it make sense to have some qualifier match, since there’s enough of us that participate?

I think it would be better for the DDK to face a much stronger opponent in a qualifier and then that opponent to go on and play in the groups, that have matches with that much of a difference within the groups.

I don’t know if it makes sense from an organizing standpoint, I’m not good at this :woman_shrugging: .
