But I'll still try because, in this case, I suspect the task is easier. And one doesn't preclude the other:)
In 2008, there was a challenge on gamerhome from Sizon. The task is to defeat the enemy hero. The deadline is the first or second day. In other words, you can attack him yourself or let him attack you.
The feature is: 1. The ability to choose a castle and hero from the start. 2. Different ways to win. I counted 4 ways. This includes the options suggested on the Chinese forum and one of my options, which is an "improved" version of Sizon's, much faster.
The map name is ѕЮБъµДМфХЅ, size - S.

I'll post a recording of my version later:)
