"Newcomer-2012. Summer"

Let's read the first post of the tournament:

6. Save files of all matches must be saved until the end of the tournament and presented upon first request from the tournament organizers or any member of the AC.

It is essential to make save files, review your own game, and your opponent's game. If you have any questions, contact the judges; in our tournament, these are experienced players, and they will help and explain.

... these actions will reduce the chance of cheating.

Those who want to cheat cannot be stopped by a transponder and "to the fullest extent"; it is easily circumvented.
These actions are like the ban on carrying liquids in airplanes in carry-on luggage. In Europe, airplanes are the cheapest mode of transportation. You fly somewhere for the weekend, there is no luggage, only a small bag with the essentials for 2 days. You cannot take a tube of toothpaste. You squeeze a little into foil for 2 days))) The same goes for a bottle of water, but there are practically no 24-hour stores there. Well, airplanes continue to explode...

This is a tournament for beginners.

Exactly, and

The main goal of the tournament is to get to know each other and gain experience in communication and gameplay.

That is what we are doing now - getting to know each other)
And in the future...
For some, this will be a start in serious tournaments; others will give up on Heroes.

And regarding those who have been known for a long time, they will easily agree to stream, for example, SevenSan; you yourself probably wouldn't mind, etc.

I'm always traveling around the world) And when visiting, you don't choose the internet; sometimes, we can't connect with an opponent for 5 hours, so there's no time for streaming.
I managed to stream from Paris on Thursdays) On other days, it's not very good) From China, they say their internet doesn't allow it. From Moscow, a significant buffer accumulates. In the last half hour, I watch together with the viewers.
I talked to some good players. They say that they don't want to stream serious, responsible games; it distracts too much, and you are already nervous and don't have time... And the viewers sometimes accidentally say something extra in the chat.
Therefore, no, I won't easily agree to it.

And do the Chinese replay the entire match in case of a disconnect?

Oh, they have a funny rule. If you disconnect, you lose. But the opponent can "show nobility" and agree to a replay.
So, good internet is the key to victory for them.
