There are general rules in Heroes3 that apply to every game you play, regardless of the town/hero class you're playing with.
General strategies depend on the size of the map, the difficulty level, the availability of resources and the surroundings of your town.
You may already use some of the strategies described here, as they are always applicable.
Any part of the game that could be considered as a general strategy and that is not mentioned in this section will either be too obvious to be called a strategy or of rather small importance in the game.
At least a basic knowledge of the game is required to be able to understand the meaning of the subsections of this section. (this actually counts for the whole site)
