Walkthroughs for custom maps.

Have you played "The Lone Knight"? I'm currently trying to figure out how to defeat King Lerdes; I've found some clues, but I haven't quite figured out the exact strategy yet.

I don't remember why (it was a long time ago), but I was only able to defeat him in AotD. Then, after forgetting something, I blocked the gate and spent a long (or not so long) time shooting at him. After the king, there's one last battle; I remember spending 1/3 of the total time I spent on the map on it.
Hans C and others praise his maps, but I didn't like Uprising because of its water-and-island design.
