But for this map, the ban on "ambushes" in the rules seems very strange. I'm even afraid to say more – they'll call it a "discussion" and throw it in the well.
P.S. I thought about it, and here's what I decided. Do what you're doing and let whatever happens, happen :) Still, we'll have to discuss something in connection with the map's originality. A closed ambush is prohibited when clearing a clearing using save-load, that is, when the terrain is randomly generated. But if there is no closed ambush during generation on the battlefield, then everything is according to the rules. But if a closed ambush suddenly appears in battle due to some OFFICIALLY permitted actions, which are determined by the specifics of the game on this map, then this is not prohibited by the rules. This is the same as banning the "Force Field" spell in Heroes 3. Definitely – nonsense. Therefore, I suggest that we clarify this issue right now, while the tournament has not progressed too far and while not too many people have signed up. So that no one has any misunderstandings about this issue during the tournament. What will the organizers say?

Dear Undergrounder, the main thing is not to block your own and others' units from all sides, and then there will be no violation.
