Club championship of the CIS countries.

We are waiting for a response from Vik and Sila... The final could be held in Rossone, perhaps even around the New Year, but will the organizers have enough time, and is it worth rushing things?

I really hope you, guys from St. Petersburg, will do it. I've been to your finals twice and know how great everything is. I think that if you decide to do it, Moscow and Minsk will also support the championship.

Regarding the timing, it's up to the organizers of the qualifying tournaments to decide; we'll figure it out together.
I think the most realistic timeframe for the final is:
at the earliest - during the January holidays,
at the latest - during the May holidays.

Within these limits, we can definitely hold all the qualifying tournaments and then the final. We'll decide together where to hold the final.

Yes, it's quite a distance from Siberia to Yekaterinburg. It takes a day by train from Novosibirsk. And the price is accordingly high. But we also have some good Heroes players. Dirty_Player, Dust, and maybe others. Relatively close to us are Barnaul and Kemerovo, and that's Dreamcatcher, Deep Mike... Just off the top of my head. I'm sure they can think of many more. Maybe, if we get a decent number of people interested, we could hold a qualifying tournament in Novosibirsk? I think it would be preferable for the Siberians. And Yekaterinburg has enough of its own Heroes players.

Yes, that would be great. You have so many great Heroes players in your region; it would definitely be a strong qualifying tournament, and it would be easy to organize. Dust came to St. Petersburg, and Dreamcatcher visited me, traveling halfway across the country, if not more.
In general, I ask you to talk to the guys... and we're waiting for an application for the qualifying tournament.

How many people do you need to gather to hold a qualifying tournament? And is there a regulation at all? I mean, 10 people have responded in this thread; does that mean there's no interest or no promotion?

You don't need 10 people; even 6-7 will do, those who can take on organizing championships in their regions. Then, the person uses their personal connections in the local community, talks to friends and neighbors. That's it, the qualifying tournament is ready. Yekaterinburg only needed to post once - "we'll do it," and that was it. And we in Michurinsk are ready to host a qualifying tournament.
Based on experience, I can say: 12 people is the minimum for holding a full-fledged tournament using the Swiss system, which guarantees both sufficient participation (by Heroes standards, of course) and a good atmosphere.
Even better is 14-16 people; it's the most convenient number, proven: it's not too many, but it's not too few; the best tournaments come out of it.
Regarding a larger number of people (not in St. Petersburg and maybe not in Minsk), I don't know. But the organizers can gather at least 10-12 people.

I can definitely come to the St. Petersburg qualifying tournaments (depending on how it all happens - in any case, St. Petersburg is nearby). And since the route to Michurinsk is already known, perhaps in September, with Eric's permission, we can visit again.
And I can also easily get to the final in Moscow, St. Petersburg, Minsk, or Michurinsk (depending on where it ends up being held). I really want to watch the game and cheer!

Tanya, if you knew how much I wanted to see you, Sasha, and Yura. We're waiting in September; this is an official invitation to the championship.
