Whose save is this?

It's clearly not a top player's save.

Regarding the topic, in my opinion:
1. It looks very much like a maphack.
2. There's nothing particularly wrong with it. You can run through the desert with a passfight because the game shows that it's the only remaining part of the treasure. Or you can fight. It's up to the author.
3. and 4. I'm not sure. I would take the Pope, although why not leave it for the Loch? The chance of gaining experience is 25% in the first case, and I don't remember how much in the second, something like 33%.
5. I didn't understand the English description, but judging by what I saw, taking the Utopia from under the opponent's nose is a very logical move. Then either bribe or rely on luck in the form of control and that the opponent doesn't have chains. The fact that Tiaz settled in the city is also a logical decision. Returning home means giving up the Utopia and the strategic dungeon to the opponent. The question is, what was Tiaz doing in that area with the crypts?

Yesterday, I talked to the author of the saves, and in some moments, he quite logically explained the reason for his actions. The main thing he's right about is that these saves are taken out of the game; you need to watch the whole game to understand the reason for any actions. If you watch a dozen games of any player, you'll find similar snippets in everyone's games.
There's an article by Vik about recognizing maphacks; it clearly explains that you need to watch many games of a specific character, study their playing style, and only then draw conclusions.
Regarding these saves, I won't say whether there was a maphack or not, but I've known this player for a long time, and he hasn't been caught doing something like this, but he has been caught doing something else: thinking outside the box.
