How do you like the OFB-7 tournament format?
There are many different Swiss systems. Which specific version was chosen by the organizer, and what tournament considerations were behind it, is unclear. Why were exactly 7 rounds chosen? After all, if we proceed from the formula for such tournaments
The minimum number of rounds is calculated using the formula: log2 N + log2(k-1), where N is the number of participants, and k is the number of prize-winning places
with N=80, k=7, we get 6.3219+2.5849 = 8.9068
That is, for a more or less fair selection of 7 people, at least 9 rounds should have been played, and as it is, it's like a selection of those who came to "refuel" first. By the way, then there would be an opportunity to correlate the points not earned in random-anarchic matches.
There were no real surprises, as all the templates had been played in other tournaments. And, in fact, in such a tournament, it makes sense to gather under one banner all the more or less popular templates: L, XL, anarchy, blitz, fixed, and indeed some surprising "out of the bag" (or even an unplayed one, or with extremely unusual conditions).
There are other options for Swiss systems. There could even be one where players choose their opponents themselves. The plus is flexible deadlines, the minus is the same deadlines (they can be extended by individual players). There is also the MacMahon system (I haven't studied it in detail, but it exists). You can also fight against draws by awarding 3 points for a win and 1 for a draw – this is very stimulating for players in long tournaments. And it is very bad when a player wins, takes points from someone, and then skips games. In multi-round tournaments, this disrupts the system (in knockout tournaments, this does not affect anything). In this case, you can impose a penalty on the Buchholz score, for example, or cancel the points in the end.
And one more thing. In the last rounds, the standings could have been published more often, and intermediate comments could have been made, so that there would be some intrigue in sight. But as it was, it ended rather weakly and boringly :smile13:
Also, on the panic-balance, control magic should be banned! It's frustrating to lose because of these flaws.
But overall, thanks to Kostya for his efforts – it was fun, and at times, with unexpected strategies, I even enjoyed it!)
2. Regarding the timeframe, it's 900 times.
3. Full P.) The format is cool, but for any other cool tournament, just not for the Fischer Random Chess Championship. It took 3 years to move away from CMs and learn to create templates... And here, it's 3 steps back...

and all sorts of draws and awards are annoying,

By the way, if anyone has any ideas regarding OFB-8, please share them.
I knew from the beginning that 9 rounds were needed, but I deliberately made it 7, because firstly, we don't have an extra month, and secondly, people wouldn't last through 9 rounds. Looking at the reports, it's clear that there are fewer and fewer participants; people are simply losing interest in the tournament. I may be wrong, but I made that decision.

Out of 10 participants, only 4 are top players.
Who is number 4? :confused:

In other words, you believe that FIDE uses an unfair system in chess tournaments at all levels?
I don't remember seeing any Olympic sports using the Swiss system to determine the winner. In tennis, they could easily hold tournaments using the Swiss system (there are many players), but they don't.
Its pros and cons are well described on Wikipedia; what one considers more important is another matter. In this case, I think the knockout system wins because there aren't too many players, and until the very last defeat, everything depends only on your own games, regardless of how other pairs play.

Message from HeLlight:
haven't seen such excellent performance in any tournament for 2 years
largely due to judging game disputes and understanding that you won't be waited for... I think it should be implemented everywhere (at least before the final stages of tournaments); I'm tired of all sorts of latecomers... some people have this chronically.
