I, as a party with the right to make claims from the judges' point of view, will simply express my modest opinion.
It is simply unfair to lose in a Grand Opening.
There is definitely a shop there, which is a key object in some
martial arts, and therefore the opponents are not on equal terms.
Because one can jump, and the other cannot (as in this game, I had a portal).

I removed the lyrical part; I will answer the rest in substance. I touched upon this issue based on a completely different situation, and in that situation, everything was normal and within the rules. I will take your opinion into account if I decide to hold more Tournaments. I agree that if one Grand Opening has a portal, and the other has nothing, the latter will be in a more pleasant situation in terms of visiting shops (which still need to be captured), and it can simply open the Grand Opening and thus protect itself from the sudden appearance of an opponent (which is important when the city is just a step away). But here's how people are: one has their own quirks, and the other has their own. One is honest and consistent in everything, while the other believes that one can compromise, especially in virtual space, where 99% of us have never seen and will never see each other. And I'm saying all this because, in principle, you can ban anything that might give one an advantage over the other, but that's not the problem. The problem is, who will control all these bans and how? Appealing to conscience? Please, we are not defending our homeland here, nor are we fulfilling our parental duty to our parents (or children). You can't look into everyone's soul, and no one will let you. Appealing to honesty? As I said, everyone has their own concept of it, and no one owes anything to anyone here. Therefore, I am a realist and try to ban what can at least be determined technically and mathematically. The idea of banning scanners was not mine; it was passed down, but as long as there is no anti-scanner, this ban is meaningless, like saying "I said it's forbidden," and convincing myself that everyone obeyed. It is also nonsense to say that you cannot use cheat codes to reveal the map. You can't lose a game for your opponent with your own caravan – great, but who will find out? And this is far from everything – are you feeling sad? I'm also sad, but I'm a realist and perceive crap as a stinky substance, not trying to abstract from it. So, until there are strict mechanisms to combat and counter all of the above, stamping out and multiplying uncontrolled bans is, in my opinion, foolish.
