- How long did it take to capture the castle, get into the boat, and what was the green hero doing at that time? It wouldn't work for me because the green hero was running around the castle at that time.
2. Pay attention to the hints: a swamp creature will move faster in the swamp than a Pegasus.
3. The green hero can do whatever he wants - there can't be a zugzwang in Heroes, of course, but the game will still force him away from the castle if it considers that Ivor is at a safe distance. Don't forget that you are playing against a rather primitive AI, not a human.:smile13:
Note: Zugzwang is a position in chess where the obligation to make a move is disadvantageous for the player.
