I posted this guide in ol' forum. But it wasn't finished, because I wanted a map from the map from above (perfect english) before working on. And then my guide was forgotten since I wasn't on the new forum.
I would continue it now, but I have no warcraft 3

Anybody wants to finish it?
This guide is about a scouting strategy for titans.
I don?t know a name for it, so I just invented one myself :] Blockscouting!
Blockscouting uses the path a unit takes if you order it to move to a certain point.
If you order a unit to a point it?ll always take the fastest way. And if there is no way to the target point it?ll go to the nearest accessible point to the targeted point. Now the fact this technique relies on:
If buildings block a path the ordered unit will still walk on the fastest path or to the nearest point EVEN IF THE BUILDING HASN?T BEEN SEEN YET.
If you didn?t get it: No worries, here is an example:
I use this base to show you:

The titan tries to find out if there is some in this lumber camp, but he doesn?t wants to use a pearl to check it.
So he just clicks at the point in the base to move in there.

But what happens?

The titan doesn?t walk north to go around the trees and move into the base. He just moves closer to the trees.
This tells us the titan can?t get in there just by moving. But why? Because the path is blocked.
Now the titan thinks: ?I can?t get in. Hmmmm, but usually I can get in this base. Hmmmm, something blocks my path.
Conclusion: There must be a building of my enemies blocking the path!?
So the titan knows: something is there.
And as we see in last screenshot: it?s true. There is a magnataur inside and a wall is blocking the path

This is the easiest way to use Blockscouting and with this you can check whether something is in a base spot or not without entering.
There are billions of possibilities to use it, but I?ll still post a few of them if Darox gives me the ID map.
If you consider continuing the guide you should know this is only the basic use of the strategy. There are certain spots where it's far more effectiv then this. I know 2 of them. Tell me if you're interested.
