you can do a zerg rush on this map but the probability of success is very low mainly because it's a big map. besides, it's not like his enemy's an amateur. Xellos is one of the best terran players in the world (if not the best).
actually, what the commentators are saying isnt that big of a deal, its just basic stuff.
shark didnt seem like he wanted to play, that all in move wasnt necessary, could've tried to make defilers.
