Can you win any secenerio ?

That is very good points you make, I think good tactics make for a good chance in most if not all of the games I have played.
Take time look at the map, the roads and buildings, trees and in general the landscape.
Some rivers, you can cross at points that initially you would not notice.
Lots of forest trails lead to good movement where normally its looks like a no go.
The odd hex, gives you brilliant LOS, get a unit in there and keep still, its amazing what you will see.
