I think Event 7B is a real success (still waiting for final match) and 7A worked alright. Our biggest problem for 7A was that somehow the posts got into BBO News and we got so many people who registered without even knowing what a challenge is. Given the community gets bigger and we are only amateur organizers, we will make some changes again:
Event 8 will be a single-tournament. The format will be similar to Event 7B (RR then KO). However, we will open it up to all players with the following way:
>> People who are top in the MP list will automatically join the Round-Robin stage.
>> People who are not qualified directly (either low in the MP list or first timers) will have to play a Qualifying Knockout (one or two rounds based on your MPs). We think that this will also help us to take action against people who register but don't play before they mess up the sensitive RR format.
* The games will be 14 to 16 boards with MP & non-best hand.
* Players are expected to play 5 to 7 matches per week.
* Players have to follow the post daily.
We are also thinking of a side Swiss (actually Danish, so repeat games are possible), people who want to play in a slower pace or people who get knocked out in the Qualifying stage. This event will be IMP, non-best hand and will be 2 matches per week.
We will open the registration for main event soon. Let me know if you have any feedback or thoughts.
Best,
Ovunc
Note: We need one more organizer who can spend some time and help us regularly. Please write me here or via BBO.

# of players for KO stage
2 to the integer power, this one is obvious.
# of players for RR stage
If we have 8n or 4n entrants, the RR set up will be extremely easy. Just make it 8 or 4 group of n players, each group advance 2^m (<n) players into KO stage.
For example,
44 players=>4 group of 11, 8 players advance from each group and we have 32 players to play KO
56 players=>8 group of 7, 4 players advance from each group and we have 32 players to play KO
36 players=>4 group of 9, 8 players advance from each group and we have 32 players to play KO
Qualifying Knockout
Therefore # of people we need to cut down in Q round is no more than 7. Suppose we need to cut down p (<=7) people, we can let the bottom 4p or 8p seeded players play p sets of "reverse KO" (i.e. losing player move to next round, only the player lose every game is KO)
For examples
59 players=> need to eliminate 3 players => bottom 24 seeds play 3 sets of "8 adv. 7 reverse KO"
2^t advance 2^t-1 reverse KO
t rounds of KO will be played, if you win any match, you advance to RR stage, if you lose/decide to not play/no response then you play the next day (if not the last day). Each match should be very short I recommend 64/2^t boards per round and must be completed within 24*max(1,4-t) hours.
Example
61 players enter
Top 21 seeds get byes to RR. The other 40 players play 5 sets of "8 adv. 7 reverse KO"
Day 1: If you don't have bye, you play a 8 boards match with an opponent. 20 winners Q, other 20 players play Day2.
Day 2: Similar to Day 1, 10 winners Q, 10 players play Day3.
Day 3: Similar to Day 1&2, 5 winners Q, 5 players who lose all matches are eliminated (56 left).
Day 4: We can start RR with 56 people, we'll form 8 group of 7, 4 players advance from each group and therefore we have 32 players left to play KO
1 week from Day 4: we can start KO. The organization of the remaining tournament should be straight forward.
Inactive Players
In KO stage, any inactive player is eliminated from the tournament.
In reverse KO stage, inactive player is consider losing (and therefore play the next day), if both are inactive, the lower seeded player is consider losing.
In RR stage
complete vs. non-complete: The person who fail to complete the match gets 0VP, the other person gets +3IMP for each non-complete board (and converted to VP as usual).
non-complete vs. non-complete: 0VP: 0VP

In the current 7A, 8 people dropped out. 5 of them didn't respond at all, 2 of them played just 1 challenge. If the target of the Q stage is to make sure that its survivors will reliably play in the RR, it may be necessary to reject a higher number of players even if you could accomodate, say, all but three.
frank0, on 2017-April-04, 17:19, said:
For the same reason as above, I suggest that players cannot proceed to the RR unless they complete at least 2 challenges; and if someone misses just one challenge, they cannot proceed.
frank0, on 2017-April-04, 17:19, said:
This, on the other side, is very tough and almost cannot work within 24 h unless the challenges are auto-accepted.
For example, the players are announced at 0:00 h, player 1 finds the announcement and issues challenge at 10:00 h. At 18:00 player 2 may find the challenge, accept and play it but player 1 went to bed. At 24:00 the organizers will have no idea what is going on but they need the result immediately for announcing the next round.
frank0, on 2017-April-04, 17:19, said:
I believe if both are inactive, both should be out. That's the target, isn't it?
I'm afraid this will complicate things a lot. But how about the following: Let's say you have 33 people in the Q stage, you want 4n winners. Everyone has 3 opponents announced at 0:00 h. All challenges should be issued and accepted before 24:00. Results must be reported by 72:00. If a challenge is pending at, say, 60:00 h, a player may report to the forum that he played it and the responsibility for playing and reporting the result is now with the opponent. If 7 players fail to complete a challenge, we have 26 successful players of which 24 may be winners and 2 unfortunate losers. This will include some 'winners' who lost all 3 challenges, but why not?
Oh, one more thing: We may have players who don't want to play the fast event but who may want to play the 'side swiss', if there is one. Some of them might decide to do so only after playing the Q stage ...

Now, I understand franks's suggested approaches. However, before making a decision on the system, I always ask the following question: What are we trying to optimize? We are not an official body or something like World Challenge Bridge Organization. We are members of a forum and we want to have fun. Therefore, the best system for me is the one which maximizes the fun while being as fair as possible.
Frank forgets about this and goes to fairness part - he also ignores all these frictions. In a KO, we have so many logistic issues:
>> KO does not let you have a buffer zone, a small problem delays everything at some point.
>> If it goes like 4, 5 or 6 rounds and if you have to play 4 sets in 5 days, you basically need to have BBO as the main part of your life. You have to play during a weekend getaway, because you have to. Youu cannot just send 4 challenges to same person and get done in one day. You have to wait for him to complete, you have to follow the posts etc.
>> Let's say you lost in the first round, you need to wait for others to finish the whole thing.
What are the advantage of RR?
>> Buffer - for example, you can keep up with only playing in the weekend.
>> You play vs. a lot of cool people. Especially if the group is big, it is really cool.
>> You play all the time before the short playoffs.
Note that it took 30 people 13 days to complete a full Round Robin (with 2 groups, so 14 matches). It was near perfect. Imagine that we have something like a 16 x 2 groups again, with most coming from the regular entrants. If somebody wants to join, they must show that they can play a challenge and they can play in a good pace:) I don't want to deal with inactive players - there is no good way of doing this. So, the best strategy is to have players who you are sure that will be active.
Anyway, I somehow convinced Frank that we just list the entrants and then find a cut-off in the MP list, decide on direct qualifiers and then arrange the qualifying stage for others. We will open the registration page soon.
Cheers,
Ovunc

Agree. Auto-accepting challenges makes everything smoother and less frustrating. But doesn't that now happen automatically as long as you are marked as friends?

Then they play the side event. We had like 30 people who played 14 matches in 13 days last time - enough players will be there.

Yes but that does not help in a tournament with one challenge per opponent if you don't know in advance who you will play against; well unless you make all your possible opponents your friends which would make the friends lists kind of absurd. Or well, maybe it does help if you can select someone as a friend and then send a challenge which will be auto-accepted even if they did not select you as a friend. But that's not how I would like auto-accepting to work because you have no control at all on which of your incoming challenges are auto-accepted.

1. I can help you as organizer, if you like. Actually I also can help with the Swiss event. I may use the official program of Hellenic Bridge Federation(I am official TD of HBF) in order to calculate the next rounds and keep it as normal Swiss
2. For the Swiss event we may choose a delayed Swiss format. The first two rounds will be random. Third round will be based on Round one results only. Fourth Round will be based on Rounds 1&2, fifth will be based on Rounds 1,3 & 3 and so on. Last round only will be Danish
3. I do not agree with Qualifying Knockout for the main event. It is possible someone who can play 5-7 challenges per week to be eliminated in favor for a newcomer who will drop in RR realizing that cannot follow the fast pace. It is better to have two separate events. Side event (like 7A) will be open to anyone when Main event (like 7B) will be open to anyone has at least one participation on a past Side event. (So you will be sure that he knows how challenges work and player is able to play a lot of challenges per week)
4. We may create a free web site to host past results and MPs. It is easy to create a blog or a free wordpress site for that purpose. I can do that if you like. I just need to send me in my email the files with the past results.

Thanks for the offer, I am happy to hear. So just shoot me your email address from BBO - I will contact you.

This sounds a good idea, with this we can always announce next two games. We can go with this given we have the software.

Some people really want the big event to be open to anyone in the forum. Last time we put two points that everybody who registered has to comply with by writing it down while registering. And we accommodate our regular participants. We do a similar thing, but if the number is so high, then we may need a KO stage for qualifying - note that our regular participants will play a maximum of one qualifying round vs. a newcomer may play multiple.
For newcomers, I don't think one participation is enough to clear the bar to make it to the main event automatically. That is why those people have to try the Swiss if they cannot pass the qualifying stage. Then they can collect MP there and maybe get directly in next times.

To Ovunc's reply about delayed swiss - I hope I got what you meant correctly BTW
In the delayed swiss you play the first 2 rounds with any (even random) movement. Then the positions are updated after every round, but according to the results as they were 2 rounds before.
Like this:
Round 1. Round 2.
Move according to R1 results.
R3.
Move according to R2 results.
Etc.
Although I have never tried it, it should be possible to play 2 rounds in a row generating the positions according to the results of each odd round, but only if the SW will generate 2 rounds with different matches out of the same result standings. Like:
R1. R2.
Move according to R1 results.
R3. R4.
Move according to R3 results.
Etc.
I think this requires that rounds 4, 6, 8, ... are manually generated right after 3, 5, 7,... and that you're not playing danish. But as said, I have never tried.
Anyway, the delayed concept will let you announce the next round while you're still playing the current, so you get very little advantage in generating and announcing 2 rounds together.
One question regarding the last round.
If you have e.g. 16 players and they're playing 9 rounds, why do you want the last one to be danish? You should have enough new matches available.

Is this some sort of individual with robots?
As a first timer (obviously), what requirements must be met and how would I join.
Do I need a partner or a team?
My apologies in advance for being so clueless ty

What the exact movement and scoring will be is not decided yet. There will be restrictions to register at least for one of the events in planning.
Last time we had a kind of Swiss/Danish competition called 7A.

The second was a round robin followed by a knock out called 7B.

That way a human dictates the hand instead of 3 "artificial intelligence"
Also it is more fun to be creative in bidding - not so much in declare play when I land in totally wrong contract
