just watched the replay u are brain dead lol.
He first scouted with his probe on the left side if u had any proxy barracks. Then he scouted with his zealot the right side.
With his Probe he went untill the end of the map and then straight up. He wanted to do the same with his Zealot. Only because u are some fucking shit player that only can cheese doesnt mean he has a maphack.
And only for ur informations. 2 Forums that offered sc2 map hacks are down and u can only get some chinese invite only map hacks for a couple hundred dollars per month. U are just bad
