As far as I understand, even if someone cheats extensively in IronAxe, it won't be obvious. Therefore, the only way to check a save for cheating is by looking at the description of the playthrough. So, I suggest adding a rule: "The winning save must be submitted to the organizer along with a description of the playthrough." Otherwise, it will be impossible to verify.

No, there's no need to make everyone write detailed descriptions. In Heroes 4, there's a recording of the player's moves. There's a pause function, and you can use the mouse to explore and see what troops the hero has and how they are positioned. By watching this recording (the organizer will have to watch all the recordings and all the episodes - it'll be like a film festival - Alan! Stock up on beer!), the reviewer can identify any suspicious battles. For example, if a hero suddenly jumps to 10 Chaos Devils and they disappear. And then Alan can say, "Aha, this needs to be checked." He can request the save or a description - but not necessarily for the entire game, only for the suspicious battle. No, the top three players won't be able to get away with just a video recording - they'll have to provide a full description! Both for verification purposes and for sharing tactics.
