No SOD!

I don't know how Artem did it, but on the mirror map at turn 113, he was on my side: it seems like this should be prohibited. He didn't respond in chat or to calls. In short, it's up to the judge to decide.

Yes, in tournaments where they started playing this template, there was a rule: "On the 1st week, you cannot move to the other side, so there are no rematches due to this."

Here, this point is not reflected in the rules. But references to the host are inappropriate, because firstly, the players added this template themselves, and secondly, the host immediately warned that he is not familiar with the intricacies of mirror maps.

Therefore, it is necessary to either discuss such issues with the opponent before the game, or to ensure that everything is clearly stated in the rules at the beginning of the tournament. For example, the issue of shifted guards was also not always resolved unambiguously.

Cobra was most likely genuinely mistaken, intentionally moving to the other side at such an early stage of the game. I looked at the rules of the "Mirror for a Hero" tournament, where he is participating - there is also no mention of this in the rules.

If we approach this formally, in order not to continue the game, it would be logical to do a rematch, since there is also nothing said in the tournament rules about its absence. And then you can normally discuss the rules.
