I think counter proof is when you're attacking and your enemy doesn't respond back.
eg. You setup tanks along a cliff and attack enemy buildings while your opponent doesn't have anything to hop on the cliffs. Or when you attack at two different fronts at the same time when your opponent can only focus on one-side of the map. Or when you have an invisible unit and they cannot detect it.

It has map hacks. Also, GreenTea is kind of easy actually :/ It doesn't have the proper scout and respond sense like a real player so it can't really figure out how to counter certain situations and it can't attack in two different fronts.
