Can Lichess allow Round Robin tournament?

@Rookitiki

I had to dive into this, it's been a while since I've been online on ICC. They have bots there handling the tournaments, the most prominent one being a bot called 'tomato'. This is what tomato tells me about the dr points system:

> After the ban, the dr-pts go back to 0.

> Swiss, Luton, Elim: Issues 10 points.

I can't say I have ever been a subject of tournament bans as a result of dr points. I've had a few leaves I had no control over, but generally I finished my tournaments. In general, these tournaments worked completely fine. There were occassional leavers, but this system did manage to keep it all acceptably clean and operational.

I didn’t mean the punishment system but the general setup of such tournament.

Who plays whom?
Who is the winner?
How can it be scheduled, when you don’t know who’s coming and there is even late join?

I suppose not everybody plays everybody. So what’s the difference to Swiss format?

@Rookitiki

The tournament formats were all Swiss and Round Robin. (I think they also had Elimination / sudden death.)

Nothing special about them, the implementation was identical to how that is done OTB.

For Round Robin this means that everyone plays everyone once. (This is basically the definition of Round Robin.) Winner is simply decided by who has the most points after the last round.

People could enter tournaments by 'telling' tomato 'join'. Tournaments usually started when enough players had joined. In swiss tournament there also was a 'latejoin' option during round 1. (This of course is not possible in round robin format.)

I don't think so.

let me tell why i raise this up..

if i have 6 players including myself, we want to play each other.. instead coming playing on the board, we can just arrange it online.. everyone play each other at home..

yes, of course we can manually arrange playing each other.. decide who play white and black, count manually to decide the winner... but if lichess can provide this system automatically this will come handy...

let say i want to look for my best players.. first i do swiss tournament for 50+ players..... then the top 10 players in the swiss will qualify in round robin ( we can set the time later), so we know who is the best top 4 players because they fight each other..

we eliminate the luck element in the swiss...

thats why i think round robin is a plus ...

i really appreciate what lichess have develop so far.. im also a patron.. i dont want to condemn.. if lichess decide not to do it, i still will continue supporting lichess...
